<p><b>New page</b></p><div>Many proteinogenic and non-proteinogenic amino acids have biological functions beyond being precursors to proteins and peptides.In humans, amino acids also have important roles in diverse biosynthetic pathways. [[Plant defense against herbivory|Defenses against herbivores]] in plants sometimes employ amino acids. Examples:<br />
====Standard amino acids====<br />
* [[Tryptophan]] is a precursor of the neurotransmitter [[serotonin]].<br />
* [[Tyrosine]] (and its precursor phenylalanine) are precursors of the [[catecholamine]] [[neurotransmitter]]s [[dopamine]], [[epinephrine]] and [[norepinephrine]] and various [[trace amine]]s.<br />
* [[Phenylalanine]] is a precursor of [[phenethylamine]] and tyrosine in humans. In plants, it is a precursor of various [[phenylpropanoid]]s, which are important in plant metabolism.<br />
* [[Glycine]] is a precursor of [[porphyrin]]s such as [[heme]].<br />
* [[Arginine]] is a precursor of [[nitric oxide]].<br />
* [[Ornithine]] and [[S-Adenosyl methionine|''S''-adenosylmethionine]] are precursors of [[polyamine]]s.<br />
* [[Aspartate]], [[glycine]], and [[glutamine]] are precursors of [[nucleotide]]s. However, not all of the functions of other abundant nonstandard amino acids are known.</div>FuzzyBot
