Metabolite Identification
Common NameL-Furosine
DescriptionL-Furosine, also known as cucurbate, belongs to the class of organic compounds known as alpha amino acids. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Based on a literature review very few articles have been published on L-Furosine.
