<p><b>New page</b></p><div>Some non-proteinogenic amino acids are not found in proteins. Examples include [[2-aminoisobutyric acid]] and the neurotransmitter [[gamma-aminobutyric acid]]. Non-proteinogenic amino acids often occur as intermediates in the [[metabolic pathway]]s for standard amino acids&nbsp;– for example, [[ornithine]] and [[citrulline]] occur in the [[urea cycle]], part of amino acid [[catabolism]] (see below). A rare exception to the dominance of α-amino acids in biology is the β-amino acid [[beta alanine]] (3-aminopropanoic acid), which is used in plants and microorganisms in the synthesis of [[pantothenic acid]] (vitamin B<sub>5</sub>), a component of [[coenzyme A]].</div>FuzzyBot
