Question

Which of the following is an example of monosaccharide?

• A. Galactose
• B. Lactose
• C. Maltose
• D. Sucrose

Answer 1

The correct option is A Galactose

Monosaccharides are the simplest form of sugar and the most basic units of carbohydrates. Example: Glucose, galactose and fructose.

Disaccharides are those carbohydrates which are formed when two monosaccharides are joined together. Example: Maltose, sucrose and lactose.

$\begin{array}{cc}\text{Monosaccharides}& \text{Disaccharides}\\ \text{Glucose}& \text{Maltose - Glucose + Glucose}\\ \text{Galactose}& \text{Lactose - Glucose + Galactose}\\ \text{Fructose}& \text{Sucrose - Glucose + Fructose}\end{array}$
