The galactolipids galactocerebroside and sulfatide and the proteolipid protein (PLP) and its splice variant DM20 are the most abundant lipid and protein components of central nervous system myelin.

Qualitative modifications of cerebrosides, sphingomyelin and sulphatides have been detected by mono and two dimensional thin layer chromatography. The proportion of long chain fatty acids (especially CZ4) is greatly diminished, as shown by gas chromatography. Consequently, in relation to prenatal levels galactolipids increased most rapidly in the cerebrum, followed by the cerebellum and finally by the brain stem. These regional differences were in clear contrast to data from the rat, as was the finding that only the cerebrum of undernourished children had a galactolipid concentration significantly decreased with respect to normal values.

The developmental lipid profiles in the human cerebrum, cerebellum and brain stem are presented, with special reference to galactolipids as myelin markers to trace myelination in the three main parts of the human CNS. Brain slices from 14-, 17-, and 21-day-old D2, B6, and F1 mice were incubated with [3H]galactose and [35S]sulfate. After incubation, microsomes, myelin, and oligodendroglial cells were isolated, and the galactolipids were analyzed. Groups of brains from rats of various ages–7 to 275 days–were analyzed for their contents of galactolipids (cerebroside + cerebroside sulfate), cholesterol, and the individual fatty acids of the gangliosides and glycerophosphatides. Galactolipids are the major class of lipids present in the membranes of plastids and are essential for the synthesis of a functional photosynthetic apparatus (Kobayashi, Kondo, Fukuda, Nishimura, & Ohta, 2007). Galactolipids normally exist in cells that produce and maintain the protective coating of nerve cells (myelin).

Ganglioside stearate was found to accumulate at a steady pace during the first 20 days of life, then more slowly for at least 32 days more, then to decrease. 1989-02-01 The fatty acid compositions of galactolipids in neonatal mouse brain gradually changed during the course of myelination.

The relative ratio of 2-hydroxy versus nonhydroxy galactolipids was very low at 2 days of age ( approximately 8% of total galactolipids) and increased 6- to 8-fold by 30 days of age.

It was concluded that galactose in the diet is not required by the human or cat's brain for synthesis of Abstract— Following intracerebral injection, [14C]palmitic acid was rapidly incorporated into a variety of brain lipids. After 12 hr, 78 per cent of the lipid radioactivity was in phospholipids, 15 per cent was in triacylglycerols, 1 per cent each was in free fatty acids and galactolipids, and the remainder was in other neutral glycerides. 1988-06-01 Brain galactolipids increase the transition temperature of PC-containing membranes [27]. In the PC} PS (60: 40) liposomes, the. presence of galactolipids (10–40 mol %) caused an increase in the.
