Recommendations of the Nomenclature Committee of the International Union of Biochemistry, Academic Press (1992) with later supplements: Enzyme preparations used in food processing are usually named according to the substrate to which the enzyme is applied, such as protease or amylase. Some traditional names are also in use, such as malt, pepsin and rennet.

The synthesised compounds were evaluated for their antidiabetic activity by α amylase and α glucosidase inhibitory methods and all were found to exhibit an effective inhibition against both the enzymes. Out of the four synthesised compounds, KPSV 4 was found to be most effective with percentage growth inhibition of 61.92% and 80. 46% at 1000μg when compared with other three compounds.

Peptide arrays in which peptides were immobilized on cellulose membranes through photolinkers were synthesized. The peptides were subsequently detached from the arrays by ultraviolet (UV) photolysis for 3 h, and were used to search for functional peptides that inhibit the activity of α-amylase derived from human pancreatic juice. Amino acid replacement with high-molecular-size amino acids, Arg (R), Phe (F), Trp (W), or Tyr (Y), for the first and seventh residues of amylase inhibitor peptide, GHWYYRCW, as previous reported, led to enhancement of the inhibitory effect of the peptide on α-amylase. In particular, one of the resulting peptides, RHWYYRYW, showed a stronger inhibitory effect than acarbose (which is used as a hypoglycemic agent) or inhibitor peptide GHWYYRCW.

As it says on this page, enzymes are made of protein. Your body makes many different enzymes, eg. the amylase in your saliva. When cells make enzymes, they use the information in a piece of DNA to join amino-acids together in the correct order: the sequence of amino-acids in a protein determine the 3 dimensional shape of the protein. All enzymes need the correct 3D shape to do their jobs. If the shape of the protein is wrong, it will not work as an enzyme.
