WebDisaccharides (C 12 H 22 O 11) are sugars composed of two monosaccharide units that are joined by a carbon–oxygen-carbon linkage known as a glycosidic linkage. This linkage is formed from the reaction of the anomeric carbon of one cyclic monosaccharide with the OH group of a second monosaccharide. Web(Choice B) All nucleotides and nucleosides are bonded to nitrogenous bases at the 1′ carbon of the pentose sugar through a glycosidic bond, which is a bond between a carbohydrate and any other group. (Choice D) The H group on the 5′ carbon of the pentose sugar is present in nucleosides and nucleotides. iphone charging off and on

WebSugars make anomeric bonds to become disaccharides or polysaccharides. The anomeric carbon is the carbon that is bonded to two Oxygen atoms, and is the highest priority group for naming. For disaccharides, Sucrose = 1 glucose, 1 fructose. Lactose = 1 glucose, 1 galactose. Maltose = 2 glucoses. WebGlycogen synthase is the rate-limiting enzyme of glycogen synthesis and forms the α-1,4 glycosidic bond. It is stimulated by G6P and insulin and is inhibited by epinephrine and glucagon through a protein kinase casade that phosphorylates and inactivates the enzyme.
