Amino Acids

The building blocks of proteins. They are organic molecules containing an amino group and a carboxyl group.

Biochemistry

The study of the chemical processes that occur within living organisms, focusing on the molecules and reactions involved.

Peptide Bond

The type of covalent bond that joins amino acids in a peptide chain, formed between the amino group (NH2) of one amino acid and the carboxyl group (COOH) of another.

Peptides

Short chains of amino acids, typically with fewer than 50 units.
