Amino acids are those organic compounds that contain carboxyl (-COOH) and amine (-NH2) functional groups together with a lateral chain (R group) specific to each amino acid. The core rudiments of an amino acid are carbon (C), oxygen (O), hydrogen (H), and nitrogen (N), though other rudiments are discovered in the side chains of some amino acids. Around 500 naturally taking place amino acids are recognized, however only 20 are visible in the genetic code, and can be segmented in countless ways.
