The ins and outs of sphingolipid synthesis
Sphingolipids are a complex family of compounds that share a common structural feature, a sphingoid base backbone that is synthesized de novo from serine and a long-chain fatty acyl-CoA, then converted into ceramides, phosphosphingolipids, glycosphingolipids, and other species, including protein adducts .

Types of glycerolipids and sphingolipids
Prostaglandins are synthesized from arachidonic acid. Cycloxygenase enzyme catalyzes the reaction in which C20 fatty acid is converted to prostaglandins. Leukotrienes are also derived from arachidonic acid.

Synthesis of phospholipids and sphingolipids
Glycerol is the starting material in the synthesis of glycerophospholipids. CDP-diacylglycerol is the activated intermediate of this pathway. Sphingolipids are synthesized from palmitoyl CoA and serine, initially to form ceramide. Sphingomyelins and glycolipids are synthesized from ceramide. Various sphingolipids storage diseases are resulted due to hereditary absence of hydrolytic enzymes.

Separate classes for more complex fatty acids with multiple functional groups (but nonbranched) are designated by the total number of carbon atoms found in the critical biosynthetic precursor.
Overview of Fatty Acid Synthesis • Fatty acids are built in ..
These essential precursor fatty acids are substrates for intracelluar enzymes such as elongases, desaturases, and beta-oxidation type enzymes in the and another organelle, the (involved in oxidative metabolism of straight chain and branched fatty acids, peroxide metabolism, and cholesterol/bile salt synthesis). Animals fed diets high in plant 18:2(n-6) fats accumulate 20:4(n-6) fatty acids in their tissues while those fed diets high in plant 18:3(n-3) accumulate 22:6(n-3. Animals fed diets high in fish oils accumulate 20:5 (EPA) and 22:6 (DHA) at the expense of 20:4(n-6).

Thiols and thioethers are in this class, but the thioesters are placed in the ester class because of the involvement of these and similar esters in fatty acid metabolism and synthesis.

– Serine Palmitoyltransferase (SPT), the enzyme mutated in HSAN1 patients, rings together the amino acid L-serine and Palmitoyl CoA to form the first metabolite in the sphingolipid pathway. Other enzymes then use that first metabolite to make other sphingolipids with distinct structures and biological functions.
