WebA long chain of monosaccharides linked by glycosidic bonds is a polysaccharide (poly- = “many”). The chain may be branched or unbranched, and it may contain different types of monosaccharides. The molecular weight may be 100,000 daltons or more depending on the number of joined monomers. WebApr 7, 2024 · These bonds have oxygen molecules bridging the two carbon rings. The bond gets created when the carbon of one molecule loses the hydroxyl group, and the hydroxyl group of a different monosaccharide loses the hydrogen. An oxygen molecule connects two carbon rings in these glycosidic linkages. jeedom tv samsung
