| Common Name | 2-Hydroxyhexadecanoylcarnitine |
|---|
| Description | 2-hydroxyhexadecanoylcarnitine, also known as a-Hydroxypalmitoylcarnitine, is classified as a member of the fatty acid esters. Fatty acid esters are carboxylic ester derivatives of a fatty acid. 2-hydroxyhexadecanoylcarnitine is considered to be a practically insoluble (in water) and a weak acidic compound. 2-hydroxyhexadecanoylcarnitine is a fatty ester lipid molecule. 2-hydroxyhexadecanoylcarnitine can be found in blood. Within a cell, 2-hydroxyhexadecanoylcarnitine is primarily located in the extracellular space and near the membrane. |
