The lipid A component of lipopolysaccharides from Fusobacterium nucleatum Fev 1 consists of beta-1',6-linked D-glucosamine disaccharides, which carry two phosphate groups: one in glycosidic and one in ester linkage. The amino groups of the glucosamine disaccharides are substituted by D-3-hydroxyhexadecanoic acid. The hydroxyl groups of the disaccharide backbone are acylated by tetradecanoic, he...
Novel chondroitin sulfate (CS) chains with an average molecular mass of 79.6 kDa were purified from squid liver integument. A compositional analysis of the CS chains using chondroitinases (CSases) ABC and AC-I revealed a range of variably sulfated disaccharides with GlcA1-3GalNAc(6-O-sulfate), GlcA1-3GalNAc(4-O-sulfate), and GlcA1-3GalNAc(4,6-O-disulfate) as the major ones, significant amoun...
Chondroitin sulfate (CS) has an important role in cell division, in the central nervous system, and in joint-related pathologies such as osteoarthritis. Due to the complex chemical structure and biological importance of CS, simple, sensitive, high resolution, and robust analytical methods are needed for the analysis of CS disaccharides and oligosaccharides. An ion-pairing, reversed-phase, ultra...
Definitions There are many, sometimes confusing, terms used in the literature. Simple carbohydrate (sugar) refers to monoand disaccharides; complex carbohydrate refers to polysaccharides such as starch. Common disaccharides are sucrose (glucose fructose), found in sugar cane, sugar beets, honey, and corn syrup; lactose (glucose galactose), found in milk products; and maltose (glucose glucose), ...
