Question

How are the proteins classified?

Answer 1

Hint: Proteins are a class of macromolecules that supply the cell with a number of functions. By supplying structural reinforcement and by acting as enzymes, carriers, or hormones, they assist in metabolism. Amino acids are the building blocks of proteins (monomers).

Complete answer:
Protein classification is categorized on the basis of their solubility and structure, structure, form, and size A. Solubility and Structure Classification According to this classification, proteins are categorized as basic, conjugated and derived proteins into three major classes.
Simple proteins - Simple proteins yield only amino acids on hydrolysis. These proteins are further categorized based on their solubility as well as their heat coagulability in various solvents.

Conjugated proteins: In conjunction with other non-protein compounds, such as prosthetic groups, conjugated proteins or compound proteins, simple proteins are present. The nature of non-protein or prosthetic groups is the basis for the sub-classification of conjugated proteins.

Derived proteins Proteins derived by partial or complete hydrolysis from simple or conjugated proteins by the action of acids, alkalies or enzymes.
The proteins are also subdivided into globular and fibrous proteins depending on size and form. Globular proteins are also water-soluble and fragile in nature, such as enzymes, hormones and antibodies. Fibrous proteins, strong and water-insoluble, are

Note: Haemoglobin, a coloured essential protein, is a conjugated protein composed of globin and haem. It has the capacity to bind to oxygen and transport multiple tissues via the blood. Muscle oxygen is transported by myoglobin, a related protein.
