Sphingolipid metabolites, such as ceramide, sphingosine and sphingosine-1-phosphate, are lipid second messengers involved in diverse cellular processes. There are two forms of SphK, SphK1 and SphK2.
Sphingolipids, including ceramide, sphingosine, and sphingosine-1-phosphate, act as second messengers in cells, regulating diverse functions. SphK1 and SphK2 are the two types of enzymes involved in sphingolipid metabolism.
