Cannabis Compound Identification
Common NameUrea
DescriptionUrea, also known as ur or carbamide, belongs to the class of organic compounds known as ureas. Ureas are compounds containing two amine groups joined by a carbonyl (C=O) functional group. Urea is an extremely weak basic (essentially neutral) compound (based on its pKa). Urea exists in all living species, ranging from bacteria to humans. Within humans, urea participates in a number of enzymatic reactions. In particular, urea can be converted into urea through the action of the enzyme urea transporter 2. In addition, urea can be converted into urea; which is mediated by the enzyme urea transporter 2. In humans, urea is involved in torsemide action pathway. Outside of the human body, Urea is found, on average, in the highest concentration within milk (cow). Urea has also been detected, but not quantified in, several different foods, such as thistles, kai-lans, red raspberries, biscuits, and black crowberries. This could make urea a potential biomarker for the consumption of these foods. Urea is a potentially toxic compound. A carbonyl group with two C-bound amine groups. Urea is expected to be in Cannabis as all living plants are known to produce and metabolize it.

Enzymes

General function:

Specific function:
Not Available
Gene Name:
ARG1
Uniprot ID:
P05089
Molecular weight:
34734.655
General function:
Involved in arginase activity
Specific function:
May play a role in the regulation of extra-urea cycle arginine metabolism and also in down-regulation of nitric oxide synthesis. Extrahepatic arginase functions to regulate L-arginine bioavailability to NO synthase. Since NO synthase is found in the penile corpus cavernosum smooth muscle, the clitoral corpus cavernosum and the vagina, arginase II plays a role in both male and female sexual arousal. It is therefore a potential target for the treatment of male and female sexual arousal disorders.
