Question

What type of molecule is the compound shown in the diagram?

monosaccharide
disaccharide
starch
amino acid

Answer 1

Answer : The correct option is, monosaccharide

Explanation :

Monosaccharide : It is the simple form of the carbohydrate and the sugar.

For example : Glucose, fructose and galactose are the examples of monosaccharide.

Disaccharide : it is formed by the two molecules of sugar. That means it is formed by the loss of water molecule for each linkage formed between the two sugar molecule.

For example : Sucrose and lactose are the examples of disaccharide.

Starch : It is a polysaccharide which are formed by the two or more molecules of sugar.

Amino acid : It is an organic compound that contains both amino
`(-NH_2)` and carboxyl
`(-COOH)` groups.

Hence, the given compound is a monosaccharide molecule.

Answer 2

This is a monosaccharide.  Disaccharide is two of this molecule connected by -OH group. Starch is a polymer of monosaccharide.  Amino acid contains NH2-CRH-COOH in its structure.
