Two types of protein in the body are protein and protein?

Answer 1

Proteins can be classified on many different bases as:

on the basis of chemical nature and solubility: It is based on the amino acid composition and is divided into three major classes as

SIMPLE PROTEIN: these are made up of amino acids residue only

1 Globular protein: these are spherical and oval in shape, soluble in water and other solvents and digestable

a) albumin e.g. egg

b) globulin: soluble in neutral dilute salt solution e.g. serum globulin

c) proalamines: soluble in 70% alcohol e.g. gliadin and zein maize

d) histones: basic protein soluble in water and dilute acids

On the basis of functions of protien:

1 Structural protein: e.g. keratin

2 Enzyme and catalytic protein: e.g. pepsin

3 Transport protein: Hb, serum albuin

4 Hormonal protein: e.g. hormones as insulin, adrenalin

5 Contractile protein: e.g. actin and myosin

6 Storage protein: e.g. oval albumin, glutamin

7 Genetic protein: e.g. nucleic acid ( DNA & RNA)

8 Defence protein: e.g. Ig, snake venom

9 Receptor protein: hormones and viruses
