The galactolipids have a range of important functions required for establishment of functional myelin and thus, they must be added to the expanding list of essential components of the myelin sheath. The multiplicity of functions performed by the myelin proteins and galactolipids indicates that the remarkable structure and function of myelin results from the combined contributions of its individual components.

Myelin in the mammalian nervous system has a high concentration of galactolipids [galactosylceramide (GalCer) and sulfatide] with 2-hydroxy fatty acids. We recently reported that fatty acid 2-hydroxylase (FA2H), encoded by the FA2H gene, is the major fatty acid 2-hydroxylase in the mouse brain. In this report, we show that FA2H also plays a major role in the formation of 2-hydroxy

galactolipids, TG, phospholipids) are hydrolysed, and the FA released (mainly 18:z and 18:3 acids) are progressively hydrogenated to stearic acid (18:o) with the formation of a wide range of geometric and positional isomers (Dawson & Kemp, I 970). These isomers, together with the odd-numbered and branched-chain FA The peribacteroid membrane (PBM) surrounding nitrogen fixing rhizobia in the nodules of legumes is crucial for the exchange of ammonium and nutrients between the bacteria and the host cell. Digalactosyldiacylglycerol (DGDG), a galactolipid abundant in chloroplasts, was detected in the PBM of soybean (Glycine max) and Lotus japonicus.

However, phylogenetic analysis revealed the presence of a candidate ortholog in the red algal genome, suggesting the presence of a potential coding capability for PPT (Weber et al., 2006).

The biosynthesis of galactolipids by these multiple enzyme sets must be tightly regulated to meet the cellular demand in response to changing environmental conditions. The cooperation between MGD and DGD enzymes with a possible substrate channeling from diacylglycerol to MGDG and DGDG is supported by biochemical and biophysical studies and mutant analyses reviewed herein.

Galactolipids are enriched in the chloroplast membranes of plants, where they largely outnumber other lipids such as phospholipids. Chloroplasts contain thylakoid membranes harboring the photosynthetic complexes that convert light into chemical energy. Galactolipids are required for optimal photosynthetic efficiency.

(2.A.a). Galactolipids: In galactolipids the C3 of the glycerol moiety is connected to one or more galactose residues by glycosidic linkages. The C1 and C2 of glycerol are esterified with fatty acids. Galactolipids are predominantly present in the membranes of plant cells. They are particularly abundant in thylakoid membranes of chloroplasts Galactolipids are more bioavailable than free fatty acids, and have been shown to exhibit COX mediated anti-inflammatory activity. Bio-guided fractionation of spinach leaves ( Spinacia oleracea ) revealed alpha-linolenic acid galactolipids (18:3, n-3) were responsible for inhibitory effects on tumor promoter-induced Epstein-Barr virus (EBV Mitochondria Fn : cellular respiration -> oxidizing food & supplying energy to cell Also make important biochems & help recycle PR prods Have extra oxidases Do lots of extra biochemistry endosymbionts Peroxisomes Mitochondria Plastids Plastids Present in all plant cells, but take many forms Chloroplasts do photosynthesis Amyloplasts store Galactosemia ppt 1.
