Metabolite Identification
Common NameBenzodiazepine
DescriptionBenzodiazepine belongs to the class of organic compounds known as benzodiazepines. These are organic compounds containing a benzene ring fused to either isomers of diazepine(unsaturated seven-member heterocycle with two nitrogen atoms replacing two carbon atoms). Benzodiazepine is an extremely strong basic compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Benzodiazepine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Benzodiazepine is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.

Enzymes

General function:
Involved in acyl-CoA binding
Specific function:
Binds medium- and long-chain acyl-CoA esters with very high affinity and may function as an intracellular carrier of acyl-CoA esters. It is also able to displace diazepam from the benzodiazepine (BZD) recognition site located on the GABA type A receptor. It is therefore possible that this protein also acts as a neuropeptide to modulate the action of the GABA receptor

General function:
Signal transduction mechanisms
Specific function:
Responsible for the manifestation of peripheral-type benzodiazepine recognition sites and is most likely to comprise binding domains for benzodiazepines and isoquinoline carboxamides. May play a role in the transport of porphyrins and heme. Plays a role in the transport of cholesterol across mitochondrial membranes in steroidogenic cells
