I. Enzymes and coenzymes. Regulation of metabolism. 1. Enzymes: definition, structure and properties of enzymes. - Enzymes definition are biological catalysts, which determine the rate and pattern of chemical transformations in biological systems that underlie the meta- bolic pathways. According to their chemical nature, all the enzymes are pro- teins. Shortly speaking, enzymes are designated as biological catalysts of a protein nature. Under the catalytic action of enzymes biomolecules (s...
