Metabolite Identification
Common NameDigalactosyldiacylglycerol
Description1-16:0-2-18:2-digalactosyldiacylglycerol belongs to the class of organic compounds known as glycosyldiacylglycerols. These are diacylglycerols that carry a saccharide moiety linked to the glycerol. Based on a literature review very few articles have been published on 1-16:0-2-18:2-digalactosyldiacylglycerol. This compound has been identified in human blood as reported by (PMID: 31557052 ). Digalactosyldiacylglycerol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Digalactosyldiacylglycerol 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.
