The galactolipids monogalactosyldiacyl-glycerol (MGDG) and digalactosyldiacyl-glycerol (DGDG) constitute 80% of total membrane lipids in plants. Gao et al. now show that these galactolipids function nonredundantly to regulate systemic ac-quired resistance (SAR). Furthermore, they show that the terminal galactose on the a-galactose-b-galactose

They differ from glycosphingolipids in that they do not have nitrogen in their composition. They are the main part of plant membrane lipids where they substitute phospholipids to conserve phosphate for other essential processes. Until recently, our concept of GalC and sulfatide functions had been principally defined by immunological and chemical perturbation studies that implicate these lipids in oligodendrocyte differentiation, myelin formation, and myelin stability. Recently, however, genetic studies have allowed us to re-analyze the functions of these lipids.

Until recently, our concept of GalC and sulfatide functions had been principally defined by immunological and chemical perturbation studies that implicate these lipids in oligodendrocyte differentiation, myelin formation, and myelin stability. Recently, however, genetic studies have allowed us to re-analyze the functions of these lipids. Galactolipids, mainly monogalactosyl diglycerides and digalactosyl diglycerides are the main lipids found in the membranes of plants, algae and photosynthetic microorganisms like microalgae and cyanobacteria. As such, they are the main lipids present at the surface of earth. 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. A second function of galactolipids was discovered in the past years.

Nypone is experienced to relieve joint pain and it is the galactolipid GOPO, Vitamin C contributes to the formation of collagen for normal function of bone and

As a graduate student, she studied the role of galactolipids during chloroplast development. She then switched to the plasma membrane and its lipid metabolism

Galactolipids are a type of glycolipid whose sugar group is galactose. They differ from glycosphingolipids in that they do not have nitrogen in their composition.

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. The GALC gene provides instructions for making an enzyme called galactosylceramidase. Through a process called hydrolysis, this enzyme uses water molecules to break down certain fats called galactolipids, which are found primarily in the nervous system and kidneys.

The predominant lipids Oxo-phytodienoic acid-containing galactolipids in arabidopsis: Jasmonate Thus, arabidopsides may have a dual function: as antipathogenic substances and While their precise functions are unclear, esterified oxylipins seem to play important 12-oxo-phytodienoic acid, arabidopsis-thaliana, containing galactolipids, Galactolipids containing the phytohormone 12-oxo-phytodienoic (OPDA), also called Most of the PRRs with known function in plant defense contain. Thylakoid Development and Galactolipid Synthesis in Cyanobacteria Koichiro Awai.

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. 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 Galactolipids were identified in the X-ray structures of photosynthetic complexes.

In addition, mice lacking the ability to synthesize GalC or sulfatide form dysfunctional and unstable myelin. 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.
