Metabolite Identification
Common NameBiocytin
DescriptionBiocytin, also known as biotinyl-L-lysine, 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. Biocytin exists as a solid, possibly soluble (in water), and a very strong basic compound (based on its pKa). In cattle, biocytin is involved in the metabolic pathway called the biotin metabolism pathway.
