Studies on galactosyl ceramide and lactosyl ceramide β-galactosidase
Chemistry and Physics of Lipids, 1974Abstract Galactosyl ceramide and lactosyl ceramide β-galactosidase activity was measured in extracts of previously frozen human brain. Using the assay methods described here, both galactosyl ceramide and lactosyl ceramide gave Michaelis constants of about 20 μM.

A micromethod for the determination of ceramide
Journal of Neuroscience Methods, 1982An enzymatic micromethod for the determination of ceramide is presented. The enzyme, E. coli diglyceride kinase was used to phosphorylate ceramide, as well as diglyceride with high specific activity gamma-[32P]ATP, and the two products are differentiated by their alkali stability.

Ceramide and Ceramide 1 Phosphate in the Brain
2011Ceramide (N-acylsphingosine) forms the backbone of all complex sphingolipids. It is composed of the long-chain sphingoid base, sphingosine, in N-linkage to a variety of acyl groups (varying in length from C14 to C26) (Fig. 8.1). In addition to serving as a precursor to complex sphingolipids, ceramide is a potent signaling molecule capable of regulating

Analysis and Quantitation of Ceramide
2002It is now well appreciated that many membrane lipids play important roles in the specific responses of cells to various stimuli. The sphingolipid ceramide has emerged as a relatively new addition to the group of bioactive lipid molecules, with suggested roles in the regulation of the stress response.

The occurrence of glycoconjugates (glycosphingolipids and glycoproteins) as integral constituents of membranes and cell walls has recently stimulated research activities [4, 7, 9, 12, 16, 17, 18, 19, 20]. Of special interest is the function of glycosphingolipids as cell-surface antigens, as in the Lewis antigen A-D determinants or the well-known H, A ...

Enzymatic synthesis of ceramide
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1966Abstract An enzyme which catalyzes the biosynthesis of ceramides ( N -acylsphingosines) from sphingosine and acyl-CoA derivatives has been found in chicken liver, rat brain, and guinea-pig brain. The specificity of this enzyme toward sphingosine isomers has been investigated.

INTRODUCTION Prevention of desiccation of the body is a major function of the skin. This function is performed for the most part by skin’s epidermis, with a particularly crucial contribution by the outermost layers, the stratum corneum (SC). At the skin’s surface there is a delicate balance between the water content of the SC and the environment ...
