Description
hawkinsin: structure [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]
hawkinsin : A cysteine derivative that is cysteine in which the thiol group is substituted by a [2-(carboxymethyl)-2,5-dihydroxycyclohex-3-en-1-yl]sulfanediyl group. 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.

Drug Classes (6)
| Class | Description |
|---|
| dicarboxylic acid | Any carboxylic acid containing two carboxy groups. |
| cysteine derivative | An amino acid derivative resulting from reaction of cysteine at the amino group, carboxy group, or thiol group, or from the replacement of any hydrogen of cysteine by a heteroatom. The definition normally excludes peptides containing cysteine residues. |
| cycloalkene | An unsaturated monocyclic hydrocarbon having at least one endocyclic double bond. |
| diol | A compound that contains two hydroxy groups, generally assumed to be, but not necessarily, alcoholic. Aliphatic diols are also called glycols. |
| tertiary allylic alcohol | An allylic alcohol in which the carbon atom that links the double bond to the hydroxy group is also attached to two other carbons (R4,R5 =/= H). |
| secondary allylic alcohol | An allylic alcohol in which the carbon atom that links the double bond to the hydroxy group is also attached to one other carbon and one hydrogen. |
