Glucose, Lactose, and Sucrose all end in-ose. This means they are sugars ____ which group of biomolecules do they belong to?
A
carbohydrates
B
lipids
C
proteins
D
nucleic acids
Explanation: 

Detailed explanation-1: -Simple carbohydrates which are sweet and soluble in water are also known as sugars or disaccharides and the ending of the names of most sugars is-ose. Thus, we have such names as sucrose for ordinary table sugar, glucose for principal sugar in blood and maltose for malt sugar.

Detailed explanation-2: -In short-Monomer is a general term, while monosaccharide is a specific term for the monomer that makes up a carbohydrate. A monosaccharide is a single sugar molecule. This includes glucose, fructose, and galactose. Disaccharides are double sugars, such as sucrose (table sugar).

Detailed explanation-3: -Disaccharides. Disaccharides consist of two monosaccharide units, linked together with glycosidic bonds in the or orientation. The most important of them are sucrose, lactose, and maltose. Sucrose is the most abundant and consists of a molecule of -glucose and -fructose linked together (Figure 2(a)).

Detailed explanation-4: -Sugars belong to the group of one of the major macronutrients called carbohydrates.

Detailed explanation-5: -Answer and Explanation: Glucose, fructose, sucrose, starch, and glycogen are all examples of b. carbohydrates.
