Problem: Which statement is FALSE regarding the disaccharide in Figure 1 shown below?A. Point (A) is an acetalB. Point (B) was an alcohol before becoming part of a glycosidic bondC. Point (C) is an acetalD. Point (D) is a plain alcoholE. Point (A) was a hemiacetal before becoming part of a glycosidic bond

FREE Expert Solution

The shown figure is a disaccharide of glucose molecules connected by an α (1→4) O-glycosidic bond. A hemiacetal forms when an aldehyde group reacts with alcohol in a 1:1 ratio. Additionally, when this hemiacetal further reacts with another free alcohol group, it wouldgrow an acetal.
