STRUCTURE OF PROTEIN

QUARTENARY STRUCTURE

Protein that has more than one polypeptides has a quaternary structure

TERTIARY STRUCTURE

Is referred as the highly specific 3-D configuration of protein

Four types of bond are involved: a. Disulphide bonds b. Ionic bonds c. H-bonds d. hydrophobic interactions

These bonds stabilize the 3-D configuration of the protein

SECONDARY STRUCTURE

This refers to the unique way of certain protein fold into a 3-D structure which is stabilized by H-bonds only

2 common types of secondary structure: - Alpha-helix - Beta-pleated sheet

Beta - Pleated Sheet

Alpha - Helix

PRIMARY STRUCTURE

Protein molecules are composed of large number up to 20 different amino acids joined together by peptide linkages

Subtopic

Primary Structure is defined as: It is the determination of the sequence of amino acids in polypeptide chains.

All amino acids have amino group (NH2) and a carboxyl group (COOH)
