15 صفحه اولAssessment of Sialic Acid Distribution in Mouse Epididymis
Previous studies have shown that epididymal epithelium and its secretions are critical for sperm maturation. These secretions contain many glycoconjugates with sialic acid terminal sugar. This terminal sugar by interveining in cellular interactions and masking surface receptors, has an important role in sperm maturation and protection. Moreover lectins have been employed as useful probes to det...
متن کاملSialic Acid Content of the Erythrocyte and of an Ascites
92.6 (19). Sialic acids have been found on the eryth rocyte membranes of a number of vertebrate species (5, 7, 192). Viral or bacterial neuramini dases, enzymes which cleave the a-ketosidic link age between a terminal sialic acid group and a sugar or sugar derivative (9), can liberate free sialic acid from such red cell membranes (5, 7). The surface of the mammalian erythrocyte is neg atively c...
متن کاملMeasurement of sialic acid content on recombinant membrane proteins
Background Membrane proteins such as cell adhesion molecules, receptors, transporters and ion channel proteins all have essential roles in cell-growth, migration, and flow of information, cell-cell and cell-protein communication. Membrane proteins are targets of biopharmaceutical companies because they have diverse effects on the progression of many diseases [1]. Ion channels are membrane prote...
متن کاملThe role of sialic acid synthases in sialic acid biosynthesis
Introduction The sialic acids comprise a diverse family of nine-carbon keto-sugars, the majority of which are structural derivatives of neuraminic acid (Fig. 1). Neuraminic acid has an amino moiety at the C-5 position, and carboxylate at C-2 which confers negative charge at physiological pH. Whereas unsubstituted neuraminic acid is not known to exist in nature, over 40 substituted variations (c...
