- Draw the structure of each of the following compounds: a. a polysaccharide formed by joining D-glucosamine in 1-→6-a-glycosidic linkages b. a disaccharide formed by joining D-mannose and D-glucose in a 1-4-B-glycosidic linkage using mannose's anomeric carbon c. an a-N-glycoside formed from D-arabinose and CgH;CHNH2 d. a ribonucleoside formed from D-ribose and thyminearrow_forwardListed below are descriptions that may belong to amylose, amylopectin, both, or it may not belong to either. Write A if it describes amylose, B if it describes amylopectin, AB if the statement applies to both, or O if it doesn’t apply to either. 1. Its monosaccharides are bound by at least one α-1,4-glycosidic bond. 2. It contains α-1,6-glycosidic bonds. 3. It can be broken down by the enzyme α-amylase. 4. A polysaccharide made up of gulose. 5.

- Galactose can exist as a cyclic hemiacetal because one of the alcohol groups reacts with the aldehyde. 1 2 3 4 он он о Н Он Он о CH2-CH-CH-CH-CH-C-H 6. CH2-OH OH C он 10 он C 8. H. H. OH Which carbon atom of the cyclic hemiacetal was originally a part of the aldehyde group? Carbon: Which alcohol group in the open-chain structure became a part of the cyclic hemiacetal? Alcohol:arrow_forwardThe surface of the eye is wet by tears, and to minimize evaporation, the tear layer is coated with lipids. One of these lipids is built from oleic acid and a 32-carbon fatty acid that has a double bond between carbons 9 and 10 and a hydroxyl group attached to the omega carbon. The carboxyl group of oleic acid condenses with the hydroxyl group in the longer lipid. Draw the structure of the reaction product. It’s OK to draw a condensed structure.arrow_forwardIndicate whether each of the following statements about the structural characteristics of monosaccharides is true or false. a.
