Multiple Choice

Which of the following is a monosaccharide?

Previous problemNext problem

Verified step by step guidance

Identify the general structure of a monosaccharide, which typically contains a carbon chain with multiple hydroxyl (OH) groups and either an aldehyde or ketone group.

Examine the first image: it shows a long carbon chain with a carboxylic acid group, which is characteristic of a fatty acid, not a monosaccharide.

Examine the second image: it shows a structure with an amino group and a carboxylic acid group, characteristic of an amino acid, not a monosaccharide.

Examine the third image: it shows a structure with two carbonyl groups, characteristic of a dicarboxylic acid, not a monosaccharide.

Examine the fourth image: it shows a structure with multiple hydroxyl groups and a carbonyl group, fitting the general structure of a monosaccharide.
