Glycosidic bond

The disaccharides differ from one another in their monosaccharide constituents and in the specific type of glycosidic linkage connecting them There are three common disaccharides: maltose lactose and sucrose All three are white crystalline solids at room temperature and are soluble in water We'll consider each sugar in more detail Maltose Maltose occurs to a limited extent in

What can bacteriophages do for us?

this case the lysin carries a N-terminal TMD which acts as a normal signal-arrest-release (SAR) sequence The lysin is transported by the host secretory system and accumulates in the periplasm in a inactive form [14] and its activation requires the release from the bilayer Fig 3 A: Lysis cassette of bacteriophage λ B: Dual-start motif

Conformational Populations of β

Abstract Twelve disaccharides containing β-(1→4) linkages and displaying systematic structural variations in the vicinity of these linkages were selectively labeled with 13 C to facilitate measurements of multiple NMR spin–spin (scalar J) coupling constants (J CH and J CC values) across their O-glycosidic linkages Ensembles of spin-couplings ( 2 J COC 3 J COCH 3 J COCC

Preferred solution conformation of marine natural product

glycosidic bond of an a-(axial)-carbohydrate the conformation I-A is preferred over I-B and I-C (Figure 1) This holds true for both oligosaccharides and simple 0-alkyl glycosides The conformational preference has been attributed to a combination of (a) steric preference (I-A I-B I-C) and (b) electronic stabilization (I-A = I-C I-B)

Glycosidic Linkage

Glycosidic linkage is the type of linkage between adjacent glycosylation on the main chain of polysaccharides [114] In the past three decades many studies have indicated that most polysaccharides isolated from higher plants that displayed immunomodulatory and anticancer activities mainly present as glucans with varying glycosidic linkage on their main-chain structures [64 65 108 113–116]

Glycoside

In chemistry a glycoside / ˈ ɡ l aɪ k ə s aɪ d / is a molecule in which a sugar is bound to another functional group via a glycosidic bond Glycosides play numerous important roles in living organisms Many plants store chemicals in the form of inactive glycosides These can be activated by enzyme hydrolysis which causes the sugar part to be broken off making the chemical available for use
