Parent topics

• protein [r]: A polymer of amino acids; basic building block of living systems. [e]
• amino acid [r]: In biochemistry, an α-amino acid is an organic monomer consisting of an amino group, a carboxyl group, a hydrogen atom, and a residual group (commonly denoted as simply "R") covalently bonded to a central (alpha) carbon (Cα). [e]
• polymer [r]: A compound of high molecular weight derived either by the addition of many smaller, similar molecules (monomers), or by the condensation of many smaller, similar molecules eliminating water, alcohol, etc. [e]

Subtopics

The 20 common amino acids

• alanine [r]: The second smallest of the twenty common amino acids used by living organisms to build proteins. [e]
• cysteine [r]: One of the twenty common amino acids and one of two that contains a sulfur atom. [e]
