PROTEIN STRUCTURE

PROTEIN STRUCTURE

BY: Valdemir Mota de Menezes, the Scribe


PRIMARY STRUCTURE
This is the simplest structural level and it derives all other molecular arrangements.

SECONDARY STRUCTURE
Occurs when the alpha carbons and their ligands are repeated segment molecular arrangements are polypeptide chain. There are two main modods: alpha-helix and beta-sheet

TERTIARY STRUCTURE
This structure arises from the pleated sheet or coiled helix, stabilized by hydrogen bonds. The tertiary structure is the long-distance interactions between amino acids.

quaternary structure
This type of structure is exemplified by the protein hemoglobin that has four polypeptide chains, quaternary thus are proteins with two or more chains.
