Primary structure

Definition

The primary structure of a protein is the specific sequence of amino acids in a polypeptide chain, determined by covalent peptide bonds. It dictates the protein's overall shape and function.

Amino Acids:

The building blocks of proteins, consisting of an amino group, carboxyl group, hydrogen atom, and distinctive side chain attached to a central carbon atom.

Peptide Bond:

A covalent chemical bond formed between two amino acid molecules when the carboxyl group of one molecule reacts with the amino group of another molecule, releasing water (dehydration synthesis).

Protein Folding: The process by which a protein structure assumes its functional shape or conformation through interactions among its amino acids driven by the primary structure
