Myelin lipids: A phylogenetic study
Neurochemical Research, 1986The lipid composition of CNS and PNS myelin was studied in rat, Xenopus, trout and Torpedo. The main difference lay in the proportion of cerebrosides, which decreased in the sequence rat greater than Xenopus greater than Torpedo greater than trout. In addition Torpedo CNS and PNS myelins were extremely rich in sulfatides.

Mycobacterial lipids a historical perspective
Frontiers in Bioscience, 1998Mycobacterial lipids have been studied for more than 70 years, due to the fascinating diversity of their structures and biological activities. A historical perspective, and the present status on the structure and activity of major lipids of the outer envelope of mycobacterial cells are presented : mycolic acids, which are main constituents of the cell ...

The lipid A receptor consists of several subunits. Lipopolysaccharide binding protein (LBP) is a serum protein facilitating association of lipid A with CD14. The Lipid A-LBP-CD14 complex is further delivered to Toll-like receptor 4 (TLR4), which is essential for lipid A-mediated cellular activation.

Structural Biology The membranes of eukaryotic cells have different lipid compositions in their inner and outer leaflets. Enzymes known as flippases and floppases use the energy from adenosine triphosphate (ATP) hydrolysis to translocate lipids against a concentration gradient from the outer to inner or inner to outer leaflets, respectively.

Lipid A in Helicobacter pylori
Infection and Immunity, 1992Free lipid A of Helicobacter pylori was characterized with regard to chemical composition, reactivity with anti-lipid A antibodies, and activity in a Limulus lysate assay. The predominant fatty acids of H. pylori lipid A were 3-OH-18:0, 18:0, 3-OH-16:0, 16:0, and 14:0.

Regulation of Lipid Metabolism by a Lipid-Carrying Protein
1984The overall conclusion to be made from the information presented here is that for many reasons SCP is a highly unusual protein. Some of these reasons are, first, SCP serves as cofactor for a number of different membrane-bound enzymes catalyzing specific steps in lipid metabolism.

Recent studies by several groups (46,58,61,63) have revealed that the now “classical” structure of enterobacterial lipid A, the 1,4’-bisphosphorylated β-1,6-linked glucosamine disaccharide with amide- and esterlinked 3-hydroxy fatty acids or 3-acyloxyacyl residues (25a,44), is not universally distributed amongst gram-negative bacteria. It is especially

Vitamin A and Lipid Metabolism
1961Publisher Summary The main aspects of the function of vitamin A in metabolism have been reviewed by Lowe and Morton. Since then, the problem of the functional role of vitamin A in steroid metabolism, already indicated in that review, has been developed further.

Lipid A, a constituent of the outer membrane of gram-negative bacteria, is a structurally unique molecule that does not exist in animal cells. The lipid A of most gram-negative bacteria is structurally similar, with analogous biosynthetic steps. These facts, combined with the fact that lipid A is required for the survival of most, if not all gram ...
