Hawkinsinuria is an inherited disorder which is characterized by the inability to break down the amino acid tyrosine. This results in the finding of certain metabolites in the urine, such as hawkinsin. It has a role as a biomarker and a human urinary metabolite. It is a dicarboxylic acid, a cysteine derivative, a cycloalkene, a diol, a tertiary allylic alcohol and a secondary allylic alcohol."}]
