A. Galactolipids: In the case of galactocerebrosides, the monosaccharide fixed on the ceramide is galactose. Galactose can be esterified by a molecule of sulphuric acid. The compounds are then called sulphatides. In mammals, galactocerebrosides and sulphatides are mainly located in the renal tissue and nervous tissue (myelin sheath).

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

Chloroplasts contain thylakoid membranes harboring the photosynthetic complexes that convert light into chemical energy. Galactolipids are required for optimal photosynthetic efficiency.

1).All truncated genes show high identities to AtPPT1 but low identities to AtPPT2 (Table (TableII). 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.

Abstract.

Green leaf volatiles (GLVs) consisting of six-carbon aldehydes, alcohols, and their esters, are biosynthesized through the action of fatty acid hydroperoxide lyase (HPL), which uses fatty acid hydroperoxides as substrates. GLVs form immediately after disruption of plant leaf tissues by herbivore attacks and mechanical wounding and play a role in defense against attackers that attempt to invade A defining feature of the vertebrate nervous system is the ensheathment of axons by myelin, a multilamellar membrane containing a small group of proteins and an abundance of the galactolipid galactocerebroside (GalC) and its sulfated derivative sulfatide.

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 represent the most abundant lipid class in thylakoid membranes, where oxygenic photosynthesis is performed. The identification of galactolipids at specific sites within photosynthetic complexes by x-ray crystallography implies specific roles for galactolipids during photosynthetic electron transport.
