  2. Metabolic pathway - Wikipedia

    en.wikipedia.org/wiki/Metabolic_pathway

    In biochemistry, a metabolic pathway is a linked series of chemical reactions occurring within a cell.The reactants, products, and intermediates of an enzymatic reaction are known as metabolites, which are modified by a sequence of chemical reactions catalyzed by enzymes.

  3. Bioenergetic systems - Wikipedia

    en.wikipedia.org/wiki/Bioenergetic_systems

    The term metabolism refers to the various series of chemical reactions that take place within the body. Aerobic refers to the presence of oxygen, whereas anaerobic means with a series of chemical reactions that does not require the presence of oxygen. The ATP-CP series and the lactic acid series are anaerobic, whereas the oxygen series is aerobic.

  4. Glycosaminoglycan - Wikipedia

    en.wikipedia.org/wiki/Glycosaminoglycan

    The fourth class of GAG, hyaluronic acid (HA), is not sulfated and is synthesized by three transmembrane synthase proteins HAS1, HAS2, and HAS3. HA, a linear polysaccharide, is composed of repeating disaccharide units of →4)GlcAβ(1→3)GlcNAcβ(1→ and has a very high molecular mass, ranging from 10 5 to 10 7 Da. Each HAS enzyme is capable ...

  5. Biochemistry - Wikipedia

    en.wikipedia.org/wiki/Biochemistry

    Biochemistry, or biological chemistry, is the study of chemical processes within and relating to living organisms. [1] A sub-discipline of both chemistry and biology, biochemistry may be divided into three fields: structural biology, enzymology, and metabolism. Over the last decades of the 20th century, biochemistry has become successful at ...

  6. Metabolism - Wikipedia

    en.wikipedia.org/wiki/Metabolism

    Metabolism (/ m ə ˈ t æ b ə l ɪ z ə m /, from Greek: μεταβολή metabolē, "change") is the set of life-sustaining chemical reactions in organisms.The three main functions of metabolism are: the conversion of the energy in food to energy available to run cellular processes; the conversion of food to building blocks of proteins, lipids, nucleic acids, and some carbohydrates; and the ...

  7. Proto-metabolism - Wikipedia

    en.wikipedia.org/wiki/Proto-metabolism

    A proto-metabolism is a series of linked chemical reactions in a prebiotic environment that preceded and eventually turned into modern metabolism.Combining ongoing research in astrobiology and prebiotic chemistry, work in this area focuses on reconstructing the connections between potential metabolic processes that may have occurred in early Earth conditions. [1]

  8. Metabolite - Wikipedia

    en.wikipedia.org/wiki/Metabolite

    In biochemistry, a metabolite is an intermediate or end product of metabolism. [1] The term is usually used for small molecules.Metabolites have various functions, including fuel, structure, signaling, stimulatory and inhibitory effects on enzymes, catalytic activity of their own (usually as a cofactor to an enzyme), defense, and interactions with other organisms (e.g. pigments, odorants, and ...

    Biochemistry is the chemistry of life. Biochemists study the elements , compounds and chemical reactions that are controlled by biomolecules (such as polypeptides , polynucleotides , polysaccharides , lipids and chemical messenger [ disambiguation needed ] s) and take place in all living organisms .
