2006-05-09 · Galactolipids are crucial to establish the proton- and ion-impermeable matrix of chloroplast membranes. An appropriate ratio of βGalDG to αGalβGalDG is required to maintain the intricate bilayer characteristics required for insertion, folding, movement, and conformational changes of membrane proteins ( 6 ). The abnormal myelin structures present in the mutant animals are consistent with the possibility that the galactolipids play a role in regulating or mediating proper axo-glial interactions. The further detailed analysis of these animals should help refine our understanding of galactolipid function in the myelination process. As a result of their multiple functions, they provide direct biochemical links between photosynthesis, chloroplast shape maintenance, jasmonate synthesis, phosphate starvation responses, freezing tolerance and probably other reactions. 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.

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) activation.

Galactolipids make up the bulk of photosynthetic membranes.

Galactolipids were identified in the X-ray structures of photosynthetic complexes. Deficiency of DGDG as observed in the dgd1 mutant of Arabidopsis has severe consequences for the efficiency of the photosynthetic machinery. The amount of DGDG increases when plants are …

An appropriate ratio of βGalDG to αGalβGalDG is required to maintain the intricate bilayer characteristics required for insertion, folding, movement, and conformational changes of membrane proteins ( 6 ). Crystallization and structural analysis of the photosynthetic complexes confirmed that galactolipids have critical functions in photosynthesis. Replacement of DGDG with the alternative glycolipid βGlcβGalDG provided the means to uncover specific functions of the galactolipid in photosynthesis. In photosynthesis: Lipids …compounds such as phospholipids and galactolipids.

These polar lipid molecules have “head” groups that attract water (i.e., are hydrophilic) and fatty acid “tails” that are oil soluble and repel water (i.e., are hydrophobic). When polar lipids are placed in an aqueous environment, they can line up with the fatty Galactolipids are the major lipid component of the internal plastid membrane network at every stage of their development (Selstam and Sandelius, 1984; Douce and Joyard, 1996).

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).

Oxygenic photosynthesis in cyanobacteria and plants depends on the presence of galactolipids. The ratio of the two galactolipids carrying one or two galactoses in the head group is crucial for the maintenance of membrane integrity during stress. Historically, the roles of galactolipids have been studied mainly in relation to photosynthesis, and recent advances in molecular biology with Arabidopsis and other model organisms have revealed an essential role of galactolipids in photosynthesis.

Galactolipids are the major constituents of the thylakoid membrane system, and all the genes involved in galactolipid biosynthesis were recently identified. In this chapter, I summarize recent advances in our understanding of the factors involved in thylakoid development, including regulatory proteins and enzymes that mediate lipid biosynthesis.

Recent advances in understanding the functions of galactolipids as key facilitators of various membrane-associated processes in etioplasts and chloroplasts provide important insights into the complex processes of thylakoid membrane development and photosynthetic activation in plants. Figure 1. composition ofgalactolipids can be definably manipulated in a higher plant with various substituted pyridazinones. Likewise, Chl content may also be manipulated. We suggest that the substituted pyridazinones will be valuable tools for use in clari-fying the role galactolipids andtheir componentfatty acids play in the structure and function of The galactolipids monogalactosyldiglyceride and digalactosyldiglyceride together comprise more than 77% of the photosynthetic membrane lipids of higher plant chloroplasts. We have isolated a lipase from the chloroplasts of runner beans (Phaseolus vulgaris) which is highly specific for these galactolipids. The lipid monogalactosyl diacylglycerol (MGD) is a major structural component of photosynthetic membranes in chloroplasts.

The further detailed analysis of these animals should help refine our understanding of galactolipid function in the myelination process. As a result of their multiple functions, they provide direct biochemical links between photosynthesis, chloroplast shape maintenance, jasmonate synthesis, phosphate starvation responses, freezing tolerance and probably other reactions. 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. Galactolipids are phosphorous‐free glycoglycerolipids in plants.
