Which one of the following statements is true? Amylopectin is composed of (a)pectins joined by (14) linkage (b) D-xylose and D-ribose units (c) D-glucoseunits joined by 1 4 linkage (d) Glucose and fructose joined by 12 linkage
Question
Which one of the following statements is true? Amylopectin is composed of (a)pectins joined by (14) linkage (b) D-xylose and D-ribose units (c) D-glucoseunits joined by 1 4 linkage (d) Glucose and fructose joined by 12 linkage
Solution
The correct statement is (c) Amylopectin is composed of D-glucose units joined by α 1→4 linkage.
Amylopectin is a type of polysaccharide found in plants, specifically in the starch. It is composed of D-glucose units, which are sugar molecules, and these units are joined together by α 1→4 glycosidic linkages. This structure allows it to be easily broken down for energy in the body. The other options are not correct descriptions of the composition of amylopectin.
