Metabolite Identification
Common Name3-Methoxy-4-hydroxyphenylglycol glucuronide
Description3-Methoxy-4-hydroxyphenylglycol (HMPG) glucuronide is the main form of HMPG in human urine. HMPG is a major metabolite of norepinephrine that is found in urine and cerebrospinal fluid (CSF). It has been determined that 25-50% of it is derived from brain norepinephrine. The conjugated form is reported to be derived mainly from the metabolism of systemic norepinephrine. (PMID 528605 ).

Enzymes

General function:
Involved in transferase activity, transferring hexosyl groups
Specific function:
UDPGTs are of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. This isozyme has glucuronidating capacity with steroid substrates such as 5-beta-androstane 3-alpha,17-beta-diol, estradiol, ADT, eugenol and bile acids. Only isoform 1 seems to be active.

General function:
Involved in transferase activity, transferring hexosyl groups
Specific function:
UDPGT is of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. Its unique specificity for 3,4-catechol estrogens and estriol suggests it may play an important role in regulating the level and activity of these potent and active estrogen metabolites. Is also active with androsterone, hyodeoxycholic acid and tetrachlorocatechol (in vitro).
