Which molecule shown in Figure 36 is a thiol A B C D E Which

Which molecule shown in Figure 3.6 is a thiol? A B C D E Which molecule shown in Figure 3.6 contains an amino functional group, but is not an amino add? A B C D E Humans can digest starch but not cellulose because the monomer of starch is glucose, whereas the monomer of cellulose is glucose with a nitrogen-containing group. the monomer of starch is glucose, whereas the monomer of cellulose is galactose. humans harbor starch-digesting bacteria in the digestive tract. humans have enzymes that can hydrolyze the alpha glycosidic linkages of starch but not the beta glycosidic linkages of cellulose. Lactose, a sugar in milk, is composed of one glucose molecule joined by a glycosidic linkage to one galactose molecule. How is lactose classified? as a disaccharide as a polysaccharide as a pentose as a monosaccharide The molecule shown in Figure 3.9 is a(n) polysaccharide. saturated fatty acid. triacylglycerol. unsaturated fatty acid.

Solution

Answers :

47. The thiols among all the given molecules is B

48. The molecule that contains amino functional group is A

49. The correct answer is D (starch contains alpha glycosidic linkages where as sellulaose contains beta glycosdic linkages and humans lacks enzymes that can cleaves these beta bonds in cellulose.

50. The correct answer is A ( lactose is disaccaharide)

51. The correct answer D (The mocleule shown in the figure 3.9 is the unsaturated fatty acid) some of the examples of unsaturated fatty acids includes, palmitoleic acid, oleic acid, linoleic acid and arachidonic acid.
