  2. Enzyme - Wikipedia

    en.wikipedia.org/wiki/Enzyme

    Following Buchner's example, enzymes are usually named according to the reaction they carry out: the suffix -ase is combined with the name of the substrate (e.g., lactase is the enzyme that cleaves lactose) or to the type of reaction (e.g., DNA polymerase forms DNA polymers). [15] The biochemical identity of enzymes was still unknown in the ...

  3. List of enzymes - Wikipedia

    en.wikipedia.org/wiki/List_of_enzymes

    Function: Amylase is an enzyme that is responsible for the breaking of the bonds in starches, polysaccharides, and complex carbohydrates to be turned into simple sugars that will be easier to absorb. Clinical Significance: Amylase also has medical history in the use of Pancreatic Enzyme Replacement Therapy (PERT). One of the components is ...

  4. List of proteins - Wikipedia

    en.wikipedia.org/wiki/List_of_proteins

    At the top level are all alpha proteins (domains consisting of alpha helices), all beta proteins (domains consisting of beta sheets), and mixed alpha helix/beta sheet proteins. While most proteins adopt a single stable fold, a few proteins can rapidly interconvert between one or more folds. These are referred to as metamorphic proteins. [5]

  5. Protein - Wikipedia

    en.wikipedia.org/wiki/Protein

    In vitro studies of purified proteins in controlled environments are useful for learning how a protein carries out its function: for example, enzyme kinetics studies explore the chemical mechanism of an enzyme's catalytic activity and its relative affinity for various possible substrate molecules.

  6. Membrane protein - Wikipedia

    en.wikipedia.org/wiki/Membrane_protein

    Membrane enzymes may have many activities, such as oxidoreductase, transferase or hydrolase. [3] Cell adhesion molecules allow cells to identify each other and interact. For example, proteins involved in immune response

  7. Biomolecule - Wikipedia

    en.wikipedia.org/wiki/Biomolecule

    Examples of these include cytidine (C), uridine (U), adenosine (A), guanosine (G), and thymidine (T). Nucleosides can be phosphorylated by specific kinases in the cell, producing nucleotides. Both DNA and RNA are polymers, consisting of long, linear molecules assembled by polymerase enzymes from repeating structural units, or monomers, of ...

  8. Enzyme catalysis - Wikipedia

    en.wikipedia.org/wiki/Enzyme_catalysis

    Enzyme catalysis is the increase in the rate of a process by an "enzyme", a biological molecule. Most enzymes are proteins, and most such processes are chemical reactions. Within the enzyme, generally catalysis occurs at a localized site, called the active site.

  9. Proteolysis - Wikipedia

    en.wikipedia.org/wiki/Proteolysis

    Different proteins are degraded at different rates. Abnormal proteins are quickly degraded, whereas the rate of degradation of normal proteins may vary widely depending on their functions. Enzymes at important metabolic control points may be degraded much faster than those enzymes whose activity is largely constant under all physiological ...
