Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What are the monomer units of a carbohydrate?
A
Starch
B
Sugar
C
Amino Acid
D
Nucleotide
Explanation: 

Detailed explanation-1: -The monomer of carbohydrates is a monosaccharide with the basic formula of a carbon, two hydrogen and an oxygen molecule (CH 2 0) 12 . Glucose, a product of photosynthesis, is simple sugar and a monomer with the chemical formula C 6 H 12 O 6. Glucose is commonly known as corn sugar or blood sugar.

Detailed explanation-2: -Carbohydrates can also be made up of two monomers called disaccharides. Some examples are lactose, which makes milk sweet; sucrose, which is your regular table sugar; and maltose, which is a product of starch breakdown. Each of these disaccharides is made up of two other monosaccharides.

Detailed explanation-3: -Three of the most important monosaccharides are three sugars known as glucose, fructose, and galactose. Each of these monosaccharides at the same chemical formula: C6H12O6.

Detailed explanation-4: -Simple sugars are monomers called monosaccharides. Monosaccharides contain carbon, hydrogen, and oxygen molecules. These monomers can form long chains that make up polymers known as carbohydrates, the energy-storing molecules found in food.
