Isomaltose is another isomer of maltose. Both of them are made up of two glucose units joined by a glycosidic bond. Nevertheless, isomaltose differs from maltose based on the glycosidic bond: α-1→4 occurs in a maltose whereas α -1→6, in isomaltose.
WebAmino acids via their various chemical functionalities (carboxyls, amino, and R groups) can undergo numerous chemical reactions. However, two reactions (peptide bond and cysteine oxidation) are of particular importance because of their effect on protein structure. Amino acids can be linked by a condensation reaction in which an ―OH is lost from the … Web•Disaccharides o Glycosidic bonds with oxygen as the bridge between carbon-1 of one monosaccharide unit and a carbon of the second creates disaccharides o 2-alpha-glucose=maltose o Alpha-glucose+fructose=sucrose o Galactose+beta-glucose=lactose o Linkages are designated as alpha or beta depending on the orientation of the – OH …
Web20 jan. 2024 · Saliva contains α-amylase, which randomly hydrolyzes all the (1→4) glycosidic bonds of starch except its outermost bonds and those next to branches. On the other hand glycogen being a highly branched molecule, it is evident that amylase won’t be a good enzyme to digest it due to physical structure constraints.
Web23 nov. 2024 · What are the types of glycosidic bonds? There are are two types of glycosidic bonds – 1,4 alpha and 1,4 beta glycosidic bonds. 1,4 alpha glycosidic bonds are formed when the OH on the carbon-1 is below the glucose ring; while 1,4 beta glycosidic bonds are formed when the OH is above the plane.
