Enzyme
Definition:
(n.) An unorganized or unformed ferment, in distinction from an organized or living ferment; a soluble, or chemical, ferment. Ptyalin, pepsin, diastase, and rennet are good examples of enzymes.
Example Sentences:
(1) In contrast, DNA polymerase alpha, the enzyme involved in chromosomal DNA replication, was relatively insensitive to CA1.
(2) The accumulation of lipids and enzymes such as simple estarase, lipase, beta-HDH, alpha-GDH and NADPH-reductase in those areas, suggests that lipids are not a simple excretory product.
(3) It was found that the skeletal muscle enzyme of the chick embryo is independent of the presence of creatine and consequently is another constitutive enzyme like the creatine kinase of the early embryonic chick heart.
(4) Previous attempts to purify this enzyme from the liquid endosperm of kernels of Zea mays (sweet corn) were not entirely successful owing to the lability of partially purified preparations during column chromatography.
(5) These results demonstrate that increased availability of galactose, a high-affinity substrate for the enzyme, leads to increased aldose reductase messenger RNA, which suggests a role for aldose reductase in sugar metabolism in the lens.
(6) As far as acrophase table is concerned for all enzymes and fractions the acrophase occurred during the night.
(7) This theory was confirmed by product analysis and by measuring the affinity of the substrate for the enzyme by its inhibition of p-nitrophenyl glucoside hydrolysis.
