Question

What are monosaccharides?

Answer 1

Monosaccharides are carbohydrates that cannot be further broken down into simpler units of other carbohydrates.

Galactose, C5H10O5,  glucose, C6H12O6, and fructose, C6H12O6 are examples of monosaccharides.

On the other hand, cane sugar (sucrose) is a disaccharide as it can be hydrolysed to one unit of glucose and one unit of fructose. Similarly, starch is a polysaccharide as it is composed of infinite number of glucose units.
