Galabiosylceramide is a non-acidic diglycosphingolipids, i.e. a sphingolipid with two or more carbohydrate moieties attached to a ceramide unit. It is a vital component of cellular membranes of most eukaryotic organisms and some bacteria. Its abundance relative to other lipids is usually low other than in epithelial and neuronal cells. Galabiosylceramide has also been found in small amounts in kidney and pancreas, for example. Galabiosylceramide is one of the lipids that accumulates in excessive amounts in Fabrys disease. It is the precursor of the gala series of oligoglycosylceramides. An animal tissues, biosynthesis involves addition of a second monosaccharides unit from the appropriate sugar nucleotide to a monoglycosylceramide, catalysed by a glycosyl transferase, in the lumen of the Golgi apparatus. Glycolipids are important components of the bodys immune defense system, either in haptenic reactivity or in antibody-producing potency, i.e. as cellular immunogens or antigens. Certain glycolipids are involved in the antigenicity of blood group determinants, while others bind to specific toxins or bacteria. Some also function as receptors for cellular recognition, and they can be specific for particular tissues or tumours.

PC(22:5(4Z,7Z,10Z,13Z,16Z)/24:1(15Z)) is a phosphatidylcholine (PC or GPCho). It is a glycerophospholipid in which a phosphorylcholine moiety occupies a glycerol substitution site. As is the case with diacylglycerols, glycerophosphocholines can have many different combinations of fatty acids of varying lengths and saturation attached at the C-1 and C-2 positions. Fatty acids containing 16, 18 and 20 carbons are the most common. PC(22:5(4Z,7Z,10Z,13Z,16Z)/24:1(15Z)), in particular, consists of one chain of docosapentaenoic acid at the C-1 position and one chain of nervonic acid at the C-2 position. The docosapentaenoic acid moiety is derived from animal fats and brain, while the nervonic acid moiety is derived from fish oils. Phospholipids, are ubiquitous in nature and are key components of the lipid bilayer of cells, as well as being involved in metabolism and signaling.While most phospholipids have a saturated fatty acid on C-1 and an unsaturated fatty acid on C-2 of the glycerol backbone, the fatty acid distribution at the C-1 and C-2 positions of glycerol within phospholipids is continually in flux, owing to phospholipid degradation and the continuous phospholipid remodeling that occurs while these molecules are in membranes. PCs can be synthesized via three different routes. In one route, choline is activated first by phosphorylation and then by coupling to CDP prior to attachment to phosphatidic acid. PCs can also synthesized by the addition of choline to CDP-activated 1,2-diacylglycerol. A third route to PC synthesis involves the conversion of either PS or PE to PC.

LacCer(d18:1/20:0) is a lactosylceramide or LacCer. Lactosylceramides are the most important and abundant of the diosylceramides. Lactosylceramides (LacCer) were originally called cytolipin H. It is found in small amounts only in most animal tissues, but it has a number of significant biological functions and it is of great importance as the biosynthetic precursor of most of the neutral oligoglycosylceramides, sulfatides and gangliosides. In animal tissues, biosynthesis of lactosylceramide involves addition of the second monosaccharides unit (galactose) as its nucleotide derivative to monoglucosylceramide, catalysed by a specific beta-1,4-galactosyltransferase on the lumenal side of the Golgi apparatus. The glucosylceramide precursor must first cross from the cytosolic side of the membrane, possibly via the action of a flippase. The lactosylceramide produced can be further glycosylated or transferred to the plasma membrane. Lactosylceramide may assist in stabilizing the plasma membrane and activating receptor molecules in the special micro-domains or rafts, as with the cerebrosides. It may also have its own specialized function in the immunological system in that it is known to bind to specific bacteria. In addition, it is believed that a number of pro-inflammatory factors activate lactosylceramide synthase to generate lactosylceramide, which in turn activates "oxygen-sensitive" signalling pathways that affect such cellular processes as proliferation, adhesion, migration and angiogenesis. Dysfunctions in these pathways can affect several diseases of the cardiovascular system, cancer and inflammatory states, so lactosylceramide metabolism is a potential target for new therapeutic treatments. beta-D-Galactosyl-1,4-beta-D-glucosylceramide is the second to last step in the synthesis of N-Acylsphingosine and is converted. from Glucosylceramide via the enzyme beta-1,4-galactosyltransferase 6(EC:2.4.1.-). It can be converted to Glucosylceramide via the enzyme beta-galactosidase (EC:3.2.1.23). Lactosylceramide (d18:1/20:0) is a lactosylceramide or LacCer.
