Assign the common names for disaccharides to their scientific names. 1) lactose A) α-D-glucopyranosyl (1→ 2) β-D-fructofuranoside 2) maltose B) α-D-glucopyranosyl (1→ 4) α-D-glucopyranose 3) sucrose C) β-D-galactopyranosyl (1→ 4) β-D-glucopyranose 4) cellobiose D) β-D-glucopyranosyl (1→ 4)β-D-glucopyranose

Respuesta :

Answer:

1. Lactose with C. β-D-galactopyranosyl (1-4) β-D-glucopyranose

2. Maltose with B. α-D-glucopyranosyl (1-4) α-D-glucopyranose

3. Sucrose with A. α-D-glucopyranosyl(1-2) β-D-fructofuranoside

4. Cellobiose with D. β-D-glucopyranosyl(1-4) β-D-glucopyranose

Explanation:

Lactose is made of β-D-glucose and β-D-galactose linked via 1→4 glycosidic linkage

Maltose is made of two α-D-glucose molecule linked via 1→4 glycosidic linkage

Sucrose is made of α-D-glucose and β-D-fructose linked via 1→2 glycosidic linkage

Cellobiose is made of two molecule of β-D-glucose linked via 1→4 glycosidic linkage

ajinems

Answer:

1.) Lactose(β-D-Galactopyranosyl-(1→4)-D-glucose)

2.) Maltose: 4-O-α-D-Glucopyranosyl-D-glucose.

3.) Sucrose: β-D-Fructofuranosyl α-D-glucopyranoside

4.) Cellobiose: 4-β-D-glucopyranosyl-D-glucopyranose

Explanation: disaccharides are carbohydrates that are made up of two monosaccharide joined by a glycosidic bond. These include lactose,maltose,sucrose and cellobiose. I hope this helps!
