Metabolite Identification
Common Name1,2-Dihexanoyl-sn-glycero-3-phosphoethanolamine
Description1,2-Dihexanoyl-sn-glycero-3-phosphoethanolamine, also known as 1,2-dihexanoylphosphatidylethanolamine or DHPDE, belongs to the class of organic compounds known as phosphatidylethanolamines. These are glycerophosphoetahnolamines in which two fatty acids are bonded to the glycerol moiety through ester linkages. Based on a literature review very few articles have been published on 1,2-Dihexanoyl-sn-glycero-3-phosphoethanolamine. This compound has been identified in human blood as reported by (PMID: 31557052 ). 1,2-dihexanoyl-sn-glycero-3-phosphoethanolamine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 1,2-Dihexanoyl-sn-glycero-3-phosphoethanolamine 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:
Not Available
Specific function:
Exhibits PLA1/2 activity, catalyzing the calcium-independent hydrolysis of acyl groups in various phosphotidylcholines (PC) and phosphatidylethanolamine (PE). For most substrates, PLA1 activity is much higher than PLA2 activity. Catalyzes N-acylation of PE using both sn-1 and sn-2 palmitoyl groups of PC as acyl donor. Also catalyzes O-acylation converting lyso-PC into PC.

Specific function:
Exhibits PLA1/2 activity, catalyzing the calcium-independent hydrolysis of acyl groups in various phosphotidylcholines (PC) and phosphatidylethanolamine (PE). For most substrates, PLA1 activity is much higher than PLA2 activity. Specifically catalyzes the release of fatty acids from phospholipids in adipose tissue (By similarity). N- and O-acylation activity is hardly detectable. Might decrease protein phosphatase 2A (PP2A) activity.
