Carbohydrates Overview Quiz

The most abundant type of organic molecule found in nature, they are the building blocks of all living organisms.

Large organic molecules, like proteins, nucleic acids, carbohydrates, and lipids, that are essential for life.

Organic molecules that provide energy, act as energy storage, and contribute to cell structure and communication.

Carbohydrates are the primary source of energy for most organisms.

Carbohydrates are used by organisms to store excess energy for later use.

Carbohydrates with only one sugar unit.

Carbohydrates with two sugar units.

Carbohydrates with 3-9 sugar units.

Carbohydrates with 10 or more sugar units.

Sugars that contain three carbon atoms.

Carbohydrate isomers that differ in configuration around only one specific carbon atom (excluding the carbonyl carbon).

Glucose and galactose are C-4 epimers because their structures differ only in the position of the -OH group at carbon 4.

Glucose and mannose are C-2 epimers.

Mirror image isomers of each other.

The form in which the OH group farthest from the carbonyl carbon on a symmetric carbon is on the right.

Carbohydrates containing an aldehyde group, such as glucose, galactose, and mannose.

Carbohydrates containing a ketone group, such as fructose.

Molecules with the same chemical formula but different structural arrangements. For example, glucose, fructose, mannose, and galactose are all isomers with the formula C6H12O6.

The position of the hydroxyl group on the second carbon (C2) determines the structure of these aldose isomers.

Fructose, glucose, mannose, and galactose are all isomers with the formula C6H12O6, but they differ in their structural arrangements.
