Proteins are polypeptides. They are linear chains of amino acids linked by peptide bonds. Each protein is a polymer of Amino acids. Ribulose bisphosphate carboxylase - oxygenase ( RUBISCO) is most abundant protein in whole biosphere. Proteins are of three types based on composition
1) Simple Protein - These are made up of amino acids only. Additional non - amino group are absent ,e.g,histone ,keratin
2)Conjugated Protein - They contain non -amino prosthetic groups. Depending upon prosthetic group, conjugate proteins are of several types i.e., nucleoprotein, chromoprotein glycoprotein, lipoprotein.
3)Derived protein - Are obtained by denaturation or hydrolysis of protein.
Depending on structure they are broadly classified into two categories
1) Fibrous protein
2)Globular protein
