Ceramides are a class of sphingolipids that are abundant in cell membranes. They are
important structural components of the membrane but can also act as second messengers in
various signaling pathways. Until recently, ceramides and dihydroceramides were
considered as a single functional class of lipids and no distinction was made between
molecules with different chain lengths. However, based on the development of high-
throughput, structure-specific and quantitative analytical methods to measure ceramides, it …
