Different kinds of enzymes have different amino acid sequences, which consist of 2 1 amino acid, including 8 essential amino acids. Protein is generally composed of multiple amino acid molecules.
Enzyme is a special protein with catalytic function, which consists of 200 or 300 amino acids, some of which are very large polymer structures, so enzyme is called active biomacromolecule.
Form and composition:
Because its molecular structure is very small, it is invisible to the naked eye alone, and it must be seen under an electron microscope, which is about one billionth of a centimeter (one millionth of a millimeter). Under the electron microscope, the enzyme is crystalline, colorless and transparent, mostly quadrangular, pentagonal, polygonal, and also round, so it is called crystal.
Therefore, the essence of most enzymes is protein, and protein, like other protein, also has the nature of amphoteric electrolyte, with a primary, secondary, tertiary and quaternary structure. At the same time, it will be denatured or even inactivated by some physical or chemical factors.
