Answer and Explanation:
Enzymes are organic catalysts which are protein in nature. There are two types of naming enzymes:
<h3>Trivial naming</h3>
This method involves giving enzymes names based on the names of the persons who discovered them. The names of such enzymes end with the suffix-in, for example, pepsin, trypsin. Some of these names have been retained to date.
Enzyme Nomenclature by Enzyme Commission
This is the modern method of naming enzymes. The suffix-ase is added to the substrate or the reaction which the enzymes catalyses. Every enzyme code consists of the letters "EC" followed by the enzyme. For example
EC 1 oxidoreductases- oxidoreduction reactions
EC 2 transferases- transfer of a functional group
EC 3 hydrolases- catalyse hydrolytic cleaving
EC 4 lyases - adding groups to double bonds. e.g., C-C,C-O
EC 5 isomerases - catalyse structural changes in a molecule
EC 6 ligases - joining of two molecules
Answer: Retinalogical
Explanation:
Vitamin A is a fat soluble vitamin that can be stored in the body.It belongs to the group of unsaturated organic compound which has nutritional qualities in them. Vitamin A includes retinol, retinal and retinoic acid and few provitamin A.
It has multiple functions in the body. It is very essential for eyes. It acts as the growth factor for the epithelial cells and other cells in the body.
It is also required for a good immune system inside the body.
Hence, retina logical is not an active form of Vitamin A.
