Answer :
A single molecule of sugar is called a monosaccharide. Monosaccharides are the simplest form of carbohydrates and cannot be broken down further into simpler sugars. They are made up of carbon, hydrogen, and oxygen atoms in a specific ratio.
For example, glucose is a common monosaccharide found in sugar. It has the chemical formula C6H12O6, which means it has 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms. This specific arrangement of atoms gives glucose its characteristic properties.
Monosaccharides like glucose are essential for providing energy to living organisms. They are quickly absorbed into the bloodstream and used as a source of fuel for cells to carry out various functions in the body.
