Galactosylceramides have not been found in plants. Monogalactosylceramide is the largest single component of the myelin sheath of nerves. Cerebroside synthesis can therefore give a measurement of myelin formation or remyelination. [1] The sugar moiety is linked glycosidically to the C-1 hydroxyl group of ceramide, such as in lactosylceramide.
Ceramides are a family of waxy lipid molecules. A ceramide is composed of sphingosine and a fatty acid joined by an amide bond. Ceramides are found in high concentrations within the cell membrane of eukaryotic cells, since they are component lipids that make up sphingomyelin, one of the major lipids in the lipid bilayer. [1]
The Lactosylceramides, also known as LacCer, are a class of glycosphingolipids composed of a variable hydrophobic ceramide lipid and a hydrophilic sugar moiety. Lactosylceramides are found in microdomains on the plasma layers of numerous cells. Moreover, they are a type of ceramide including lactose, which is an example of a globoside.
Ceramide glucosyltransferase (or glucosylceramide synthase) is a glucosyltransferase enzyme involved in the production of glucocerebrosides (also called glucosylceramides). ). It is responsible for the first step in synthesis of all glycosphingolipids—critical components of cell membranes—from sphingolipids, attaching a glucose molecule (glycosylation) to produce a glucocerebroside product
Sulfatide has several isoforms, including C16:0, which is found primarily in the secretory granules and toward the surface of the membrane of β cells. Secretory granules and β cells are found in the islet of Langerhans and in rat β TC3 cells. [3] Research has shown that in the pancreases of Type II diabetic mouse models, there is a ...
A second variety of Guizotia abyssinica submitted to the U.S.D.A. for Plant Variety Protection (Application Number 200500140) called 'Earlybird 50' has a crop maturity of 50 days and is a shorter, more dense plant with a higher yield and is less susceptible to lodging than the 'EarlyBird' variety. Both varieties have short enough maturities to ...
An intense blast of cold air shattered records in the central United States this week with temperatures up to 50 degrees below average. The bitter cold is pushing into the South and East to end ...
Glucosinolates occur in various edible plants such as cabbage (white cabbage, Chinese cabbage, broccoli), Brussels sprouts, watercress, arugula, horseradish, capers, and radishes where the breakdown products often contribute a significant part of the distinctive taste. The glucosinolates are also found in seeds of these plants. [1] [3]
