Metabolite Identification
Common NameSM C16:1
DescriptionSm c16:1 is classified as a member of the phosphocholines. Phosphocholines are compounds containing a [2-(trimethylazaniumyl)ethoxy]phosphonic acid or derivative. Sm c16:1 is considered to be a practically insoluble (in water) and a moderately acidic compound. Sm c16:1 can be found in blood and urine. Within a cell, Sm c16:1 is primarily located near the membrane (predicted from logp).
