| Common Name | 1,2-Distearoyllecithin |
|---|
| Description | 1,2-Distearoyllecithin, also known as DL-DSPC, belongs to the class of organic compounds known as phosphatidylcholines. These are glycerophosphocholines in which the two free -OH are attached to one fatty acid each through an ester linkage. Based on a literature review very few articles have been published on 1,2-Distearoyllecithin. This compound has been identified in human blood as reported by (PMID: 31557052 ). 1,2-distearoyllecithin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 1,2-Distearoyllecithin 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. |
