| Common Name | SM C16:1 |
|---|
| Description | Sm 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). |
