Description

The metabolism of SphingoLipids (SLs) in the ER and Golgi apparatus. Sphingolipids, or glycosyl-ceramides, are a class of lipids containing a backbone of sphingoid bases, a set of aliphatic amino alcohols that includes sphingosine. These compounds play important roles in signal transmission and cell recognition.
