Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The carbohydrate polymers (glucose, sucrose, starches) are made up of which monomer(s)?
A
nucleotides
B
glycerols and fatty acids
C
amino acids
D
monosaccharides
Explanation: 

Detailed explanation-1: -Sucrose (table sugar) is the most common disaccharide, which is composed of the monomers glucose and fructose. A polysaccharide is a long chain of monosaccharides linked by glycosidic bonds; the chain may be branched or unbranched and can contain many types of monosaccharides.

Detailed explanation-2: -The monomers of carbohydrates are the monosaccharide units that are the basic building blocks of all sugars and starches. The polymers of carbohydrates are disaccharides and polysaccharides that consist of two or more monomers respectively. Examples of monosaccharide are: glucose, fructose and galactose.

Detailed explanation-3: -This ranking includes individual monomers (monosaccharides) and the number of bonds. For example, sucrose is comprised of two monomers, glucose and fructose, which are linked by an 1, 2 glycosidic bond, having a degree of polymerisation (DP) of 2.
