Sphingolipids | Biosynthesis

The video tutorial explains the biosynthesis of sphingolipids, highlighting their importance in cell membranes, particularly in neurons and myelin sheaths. It compares sphingolipids with phospholipids, noting differences in stability and structure. The tutorial details the biosynthetic pathway starting from palmitate, involving various enzymes to produce ceramide and sphingomyelin. It also covers the degradation and recycling processes of sphingolipids, emphasizing the role of ceramide as a branch point in biosynthetic pathways.
