Detailed explanation-1: -A glycosidic bond connects two glucose molecules in a polysaccharide. The procedure of dehydration creates this bond. An ester bond exists between phosphate as well as a pentose sugar molecule in a nucleotide. In a protein molecule, hydrogen bonds exist between consecutive amino acids.
Detailed explanation-2: -Polysaccharides are long chains of monosaccharides linked by glycosidic bonds. Three important polysaccharides, starch, glycogen, and cellulose, are composed of glucose. Starch and glycogen serve as short-term energy stores in plants and animals, respectively. The glucose monomers are linked by glycosidic bonds.
Detailed explanation-3: -Polysaccharides are complex biomacromolecules that are made up chains of monosaccharides. The bonds that form these chains are glycosidic bonds.
Detailed explanation-4: -A glycosidic bond exists in the DNA molecule between sugar and nitrogen base. The glycosidic bond is formed by the nitrogen-carbon linkage between the 9’ nitrogen of purine bases or 1’ nitrogen of pyrimidine bases and the 1’ carbon of the sugar group.
Detailed explanation-5: -Amylose is an unbranched version of starch that only contains alpha-1, 4-glycosidic bonds.
