galactolipid A lipid that contains galactose. Galactolipids are characteristic and important constituents of plant membranes. Source for information on galactolipid: A Dictionary of Plant Sciences dictionary.

As such, they are the main lipids present at the surface of earth. 2006-05-09 Galactolipids make up the bulk of photosynthetic membranes. 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. 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.

Galactolipids, monogalactosyldiacylglycerol (MGDG) and digalactosyldiacylglycerol (DGDG), are the predominant lipid classes in the thylakoid membrane of chloroplasts. These lipids are also major constituents of internal membrane structures called prolamellar bodies (PLBs) and prothylakoids (PTs) in etioplasts, which develop in the cotyledon cells of dark-grown angiosperms. Analysis of

The galactosylceramidase enzyme functions to remove galactose from galactosylceramide, galactosylsphingosine, and other galactolipids. Both galactosylceramide and galactosylsphingosine have potent proinflammatory effects, and the latter molecule causes oligodendrocyte and Schwann cell death.

MGDG and DGDG in these processes. 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.

In plants, MGDG is highly accumulated in the chloroplast membranes and is an important bulk constituent of thylakoid membranes. However, precise functions of MGDG in photosynthesis have not been well understood. Here, we report a novel MGDG synthase Function Nonredundantly to Regulate Systemic Acquired Resistance in Plants Graphical Abstract Highlights Galactolipids (MGDG and DGDG) act nonredundantly in sys-temic acquired resistance (SAR) biosynthesis of both galactolipids and, consequently, also in the formation of photosynthetic membranes (Nakamura et al., 2010). A number of studies have revealed that MGD is vital for plant growth and devel-opment. The loss of MGD function in plants leads to a pale-green phenotype, defects in the chloroplast ultra- Normal Function 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.

Recently, however, genetic studies have allowed us to re-analyze the functions of these lipids. Several in vitro studies have suggested that these galactolipids transduce developmental signals, facilitate protein trafficking and stabilize membranes. In addition, mice lacking the ability to synthesize GalC or sulfatide form dysfunctional and unstable myelin.

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. In Arabidopsis leaves, under standard conditions, the enzymes MGD1 and DGD1 provide the bulk of galactolipids, necessary for the massive expansion of thylakoid membranes.
