Proteins: Functions, Structure, Properties and Classification

Explanation:

• Classification of Proteins.

Proteins are nitrogenous organic compounds of high molecular weight which play a vital or prime role in living organisms. They are made up of 20 standard a-amino acids.

• Functions of Proteins:

The main functions of proteins in human body are:

1. They serve as body building units, e.g., muscle proteins.

2. They provide support and protection to various tissues, e.g., collagen and keratin.

3. All chemical reactions in the body are catalysed by proteinaceous enzymes, e.g., trypsin.

4. They transport various molecules and ions from one organ to the other, e.g., hemoglobin, serum albumin.

5. They defend the body from harmful foreign organisms, e.g., immunoglobulin’s, fibrinogen.

6. They help to regulate cellular or physiological activity, e.g., hormones, viz., insulin, GH.

Structures of Proteins:

• Primary Structure of Proteins:

Primary structure of proteins refers to the total number of amino acids and their sequence in that particular protein.
