| Common Name | Tyrosine methylester |
|---|
| Description | Tyrosine methylester, also known as Tyrosine methyl ester hydrochloride, (L)-isomer or Tyr-ome, is classified as a tyrosine or a Tyrosine derivative. Tyrosines are compounds containing tyrosine or a derivative thereof resulting from reaction of tyrosine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. Tyrosine methylester is considered to be a slightly soluble (in water) and a very weak acidic compound. Tyrosine methylester can be found in humans. |
