Metabolite Identification
Common NameTopaquinone
DescriptionTopaquinone belongs to the class of organic compounds known as l-alpha-amino acids. These are alpha amino acids which have the L-configuration of the alpha-carbon atom. Topaquinone is possibly soluble (in water) and a very strong basic compound (based on its pKa). Topaquinone exists in all living organisms, ranging from bacteria to humans. In cattle, topaquinone is involved in a few metabolic pathways, which include the tyrosine metabolism pathway, the beta-alanine metabolism pathway, and the histidine metabolism pathway.
