Cannabis Compound Identification
Common Name(E)-p-Coumaric acid
Descriptiontrans-4-Coumaric acid or (e)-p-Coumaric acid, the trans-isomer of 4-coumaric acid, also known as 4-hydroxycinnamic acid, belongs to the class of organic compounds known as hydroxycinnamic acids. Hydroxycinnamic acids are compounds containing a cinnamic acid where the benzene ring is hydroxylated. 4-Hydroxycinnamic acid is a neutral compound. 4-Hydroxycinnamic acid exists in all living species, from bacteria to humans. 4-Hydroxycinnamic acid is found in highest concentrations in pepper (c. frutescens), pineapples, and sunflowers and in lower concentration in spinachs, kiwis, and sweet oranges. 4-Hydroxycinnamic acid has also been detected in wild rices, soursops, garden onions, hyssops, and avocado. This could make 4-hydroxycinnamic acid a potential biomarker for the consumption of these foods. 4-Hydroxycinnamic acid is also found in cannabis plants reported by Paris in 1973  (PMID: 6991645 ).

Enzymes

General function:
Involved in oxidoreductase activity
Specific function:
This is a copper-containing oxidase that functions in the formation of pigments such as melanins and other polyphenolic compounds. Catalyzes the rate-limiting conversions of tyrosine to DOPA, DOPA to DOPA-quinone and possibly 5,6-dihydroxyindole to indole-5,6 quinone.
Gene Name:
TYR
Uniprot ID:
P14679
Molecular weight:
60392.69
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. This isoform glucuronidates bilirubin IX-alpha to form both the IX-alpha-C8 and IX-alpha-C12 monoconjugates and diconjugate. Is also able to catalyze the glucuronidation of 17beta-estradiol, 17alpha-ethinylestradiol, 1-hydroxypyrene, 4-methylumbelliferone, 1-naphthol, paranitrophenol, scopoletin, and umbelliferone.

General function:
Involved in hydrolase activity, hydrolyzing O-glycosyl compounds
Specific function:
Glycosidase probably involved in the intestinal absorption and metabolism of dietary flavonoid glycosides. Able to hydrolyze a broad variety of glycosides including phytoestrogens, flavonols, flavones, flavanones and cyanogens. Possesses beta-glycosylceramidase activity and may be involved in a nonlysosomal catabolic pathway of glycosylceramide.
