Plant cellular biochemistry is not only an important field of basic science explaining the molecular function of a plant, but is also an applied science that is in the position to contribute to the solution of agricultural and pharmaceutical problems.Plant cellular biochemistry, sometimes called biological chemistry, is the study of chemical processes within and relating to living organisms. By controlling information flow through biochemical signaling and the flow of chemical energy through metabolism, biochemical processes give rise to the complexity of life. Over the last 40 years, biochemistry has become so successful at explaining living processes that now almost all areas of the life sciences from botany to medicine are engaged in biochemical research. Today, the main focus of Plant cellular biochemistry Journals is in understanding how biological molecules give rise to the processes that occur within living cells, which in turn relates greatly to the study and understanding of whole organisms.

Plant Molecular and Cellular Biochemistry is a peer-reviewed scientific journal covering research in cellular biology and biochemistry. Plant Molecular and Cellular Biochemistry Journals was a successor to the journal Enzymologia and was established in 1973 to make it possible to extend the potentialities of the periodical

Molecular biology of plants is the study of biology at the molecular level. The field overlaps with other areas of biology and chemistry, particularly genetics and biochemistry. Molecular biology of plants studies the properties of cells including their physiological properties, their structure, the organelles they contain, interactions with their environment, their life cycle, division and death. Molecular and cellular biology are interrelated, since most of the properties and functions of a cell can be described at the molecular level. Molecular biology of plants Journals encompass many biological fields including: biotechnology, developmental biology, physiology, genetics and microbiology.

Plant stress physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. Closely related fields include plant morphology (structure of plants), plant ecology (interactions with the environment), Plant stress physiology (biochemistry of plants), cell biology, genetics, biophysics and molecular biology. Fundamental processes such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed germination, dormancy and stomata function and transpiration, both parts of plant water relations, are studied in Plant stress physiology Journals.

Plant biotechnology is a field that entails applying technology on life (plants). It is a vast field that entails producing new products in a larger faster way, deviating from the conventional way of doing the same. Plant biotechnology Journals can be divided into several systems depending on what each of these entails.

Plant Biochemistry, sometimes called biological chemistry, is the study of chemical processes within and relating to living organisms. By controlling information flow through biochemical signaling and the flow of chemical energy through metabolism, biochemical processes give rise to the complexity of life. Over the last 40 years, biochemistry has become so successful at explaining living processes that now almost all areas of the life sciences from botany to medicine are engaged in biochemical research. Today, the main focus of pure biochemistry is in understanding how biological molecules give rise to the processes that occur within living cells, which in turn relates greatly to the study and understanding of whole organisms. Plant Biochemistry is closely related to molecular biology, the study of the molecular mechanisms by which genetic information encoded in DNA is able to result in the processes of life. Depending on the exact definition of the terms used, molecular biology can be thought of as a branch of Plant Biochemistry Journals as a tool with which to investigate and study molecular biology.

Plant cell physiology are eukaryotic cells that differ in several key aspects from the cells of other eukaryotic organisms. Their distinctive features include: A large central vacuole, a water-filled volume enclosed by a membrane known as the tonoplast that maintains the cell's turgor, controls movement of molecules between the cytosol and sap, stores useful material and digests wasteproteins and organelles. A cell wall composed of cellulose and hemicellulose, pectin and in many cases lignin, is secreted by the protoplast on the outside of the cell membrane. Plant cell physiology Journals contrasts with the cell walls of fungi (which are made of chitin), and of bacteria, which are made of peptidoglycan. Specialized cell-to-cell communication pathways known as plasmodesmata pores in the primary cell wall through which the plasmalemma and endoplasmic reticulum of adjacent cells are continuous.

Genetics of plant physiology, known as plant growth regulators (PGRs) or phytohormones, are chemicals that regulate a plant's growth. According to a standard animal definition, hormones are signal molecules produced at specific locations, that occur in very low concentrations, and cause altered processes in target cells at other locations. Unlike animals, plants lack specific hormone-producing tissues or organs. Plant hormones are often not transported to other parts of the plant and production is not limited to specific locations. Genetics of plant physiology are chemicals that in small amounts promote and influence the growth, development and differentiation of cells and tissues. Hormones are vital to plant growth; affecting processes in plants from flowering to seed development, dormancy, and germination. They regulate which tissues grow upwards and which grow downwards, leaf formation and stem growth, fruit development and ripening, as well as leaf abscission and even plant death.Genetics of plant physiology Journals deals with the above topics.

Phytochemical Analysis are chemical compounds that occur naturally in plants (phyto means "plant" in Greek). Some are responsible for colour and other organoleptic properties, such as the deep purple of blueberries and the smell of garlic.Phytochemical Analysis may have biological significance, for example carotenoids or flavonoids, but are not established as essential nutrients.There may be as many as 4,000 different phytochemicals.The above all topics are covered in Phytochemical Analysis Journals.

Green chemistry Journals, is also called sustainable chemistry, is a philosophy of chemical research and engineering that encourages the design of products and processes that minimize the use and generation of hazardous substances.

Theoretical Chemistry is an exciting, contemporary and broad field: rooted inchemistry.Theoretical Chemistry Journals straddles the vibrant interfaces between chemistry, physics, materials science and biology, and encompasses any application of mathematical and computational techniques to problems and systems ofchemical and related interest.

Electrochemistry is the study of electricity and how it relates to chemical reactions. In electrochemistry, electricity can be generated by movements of electrons from one element to another in a reaction known as redox reaction, or oxidation-reduction reaction.Electrochemistry Journals deals with electricity and chemical reactions.

Heterocyclic chemistry is the branch of chemistry dealing with the synthesis, properties and applications of these heterocycles. In contrast, the rings of homocyclic compounds consist entirely of atoms of the same element. Although heterocyclic compounds may be inorganic, most contain at least one carbon.Heterocyclic chemistry Journals deals with the synthesisand properties of heterocycles.

Biotechnology-2015 aims to promote the international and national exchange of ideas, promote collaborative research network among academia and industry. Besides this dissemination of knowledge this world congress brings an opportunity for professionals to build up a scientific and professional network as well.

Biochemistry is the chemistry of living systems, or the study of what living systems are composed of and how they function at the molecular level. As a discipline, Biochemistry lies at the nexus of Chemistry and Biology, and seeks to understand the physicochemical basis for the traits of life, including metabolism, heredity, and all aspects of physiology and pathophysiology. The science of Biochemistry broadly includes molecular biology, as well as bioorganic, bioinorganic, and biophysical chemistry; and it relates to all biomedical fields including immunology, neurobiology, cancer biology, pharmacology, and developmental biology.

Fermentation – Wikipedia, the free encyclopedia

Fermentation is a metabolic process that converts sugar to acids, gases or alcohol. It occurs in yeast and bacteria, but also in oxygen-starved muscle cells, as in the case of lactic acid fermentation. Fermentation is also used more broadly to refer to the bulk growth of microorganisms on a growth medium, often with the goal of producing a specific chemical product. French microbiologist Louis Pasteur is often remembered for his insights into fermentation and its microbial causes. The science of fermentation is known as zymology.

Fermentation takes place in the lack of oxygen (when the electron transport chain is unusable) and becomes the cells primary means of ATP (energy) production.[1] It turns NADH and pyruvate produced in the glycolysis step into NAD+ and various small molecules depending on the type of fermentation (see examples below). In the presence of O2, NADH and pyruvate are used to generate ATP in respiration. This is called oxidative phosphorylation, and it generates much more ATP than glycolysis alone. For that reason, cells generally benefit from avoiding fermentation when oxygen is available, the exception being obligate anaerobes which cannot tolerate oxygen.

The first step, glycolysis, is common to all fermentation pathways:

Pyruvate is CH3COCOO. Pi is phosphate. Two ADP molecules and two Pi are converted to two ATP and two water molecules via substrate-level phosphorylation. Two molecules of NAD+ are also reduced to NADH.[2]

In oxidative phosphorylation the energy for ATP formation is derived from an electrochemical proton gradient generated across the inner mitochondrial membrane (or, in the case of bacteria, the plasma membrane) via the electron transport chain. Glycolysis has substrate-level phosphorylation (ATP generated directly at the point of reaction).

Humans have used fermentation to produce food and beverages since the Neolithic age. For example, fermentation is used for preservation in a process that produces lactic acid as found in such sour foods as pickled cucumbers, kimchi and yogurt (see fermentation in food processing), as well as for producing alcoholic beverages such as wine (see fermentation in winemaking) and beer. Fermentation can even occur within the stomachs of animals, such as humans. Auto-brewery syndrome is a rare medical condition where the stomach contains brewers yeast that break down starches into ethanol; which enters the blood stream.[3]

To many people, fermentation simply means the production of alcohol: grains and fruits are fermented to produce beer and wine. If a food soured, one might say it was 'off' or fermented. Here are some definitions of fermentation. They range from informal, general usage to more scientific definitions.[4]

Fermentation does not necessarily have to be carried out in an anaerobic environment. For example, even in the presence of abundant oxygen, yeast cells greatly prefer fermentation to aerobic respiration, as long as sugars are readily available for consumption (a phenomenon known as the Crabtree effect).[5] The antibiotic activity of hops also inhibits aerobic metabolism in yeast[citation needed].

Fermentation reacts NADH with an endogenous, organic electron acceptor.[1] Usually this is pyruvate formed from the sugar during the glycolysis step. During fermentation, pyruvate is metabolized to various compounds through several processes:

Sugars are the most common substrate of fermentation, and typical examples of fermentation products are ethanol, lactic acid, carbon dioxide, and hydrogen gas (H2). However, more exotic compounds can be produced by fermentation, such as butyric acid and acetone. Yeast carries out fermentation in the production of ethanol in beers, wines, and other alcoholic drinks, along with the production of large quantities of carbon dioxide. Fermentation occurs in mammalian muscle during periods of intense exercise where oxygen supply becomes limited, resulting in the creation of lactic acid.[6]

Georgia Tech Chemistry & Biochemistry

Nanoparticles (NPs), in particular noble metal nanoparticles, have been incorporated into many therapeutic and biodiagnostic applications. While these particles have many advantageous physical and optical properties, little is known about their intrinsic intracellular effects in biological environments. Here, we report the possible cell death mechanisms triggered in human oral squamous cell carcinoma (HSC-3) cells after exposure to extracellular, cytoplasm, and nuclear localized AuNPs and AgNPs. NP uptake and localization, cell viability, ATP levels, modes of cell death, ROS generation, mitochondrial depolarization, and the levels and/or translocation of caspase-dependent and caspase-independent proteins were assessed under control and localized metal nanoparticle exposure. Exposure to AuNPs resulted the adoption of a quiescent cellular state, as AuNPs caused a decrease in intracellular ATP, but no change in viability or cell death populations. However, AgNP exposure significantly reduced HSC-3 cell viability and increased apoptotic populations, especially when localized at the cytoplasm and nucleus. Increased cell death populations were linked to an increase in intracellular ROS generation. Western blot analysis indicated cytoplasm localized AgNPs and nuclear localized AgNPs utilized a caspase-independent apoptotic pathway that involved the nuclear translocation of AIF and p38 MAPK proteins. These results demonstrate that the degree of cytotoxicity increases as AgNPs move from extracellular localization to nuclear localization, whereas changing AuNP localization does not trigger any significant cytotoxicity.
