Question

The most common monomer of carbohydrates is a molecule of

• A. Glucose
• B. Maltose
• C. Amino acid
• D. Phospholipid

Answer 1

The correct option is A Glucose

Glucose is the simplest 6 carbon molecule that is the most common monomer of carbohydrates. It is the most abundant monosaccharide with the molecular formula C${}_6$H${}_1$${}_2$O${}_6$. It is mostly made by plants and green algae during photosynthesis.

Maltose is a disaccharide made of two molecules of glucose units.

An amino acid is the monomer of the proteins or polypeptide chains.

Phospholipids are mainly present in the cell membrane of animals that are made of phosphate and lipid molecules.

So, the correct option is 'Glucose'.
