Overview

Monosaccharides are the simplest carbohydrates, consisting of single sugar units like glucose and fructose. They play a crucial role in energy production and serve as building blocks for more complex carbohydrates. Understanding their structure and function is essential in biochemistry and related f...

Key Terms

Monosaccharide
The simplest form of carbohydrate, consisting of a single sugar unit.

Example: Glucose is a common monosaccharide.

Optical Isomerism
A form of isomerism where molecules have the same molecular formula but differ in the arrangement of atoms in space.

Example: Lactic acid has two optical isomers.

Chirality
A property of a molecule that makes it non-superimposable on its mirror image.

Example: Many amino acids are chiral.

D and L Configuration
Systems used to denote the configuration of chiral molecules, based on the orientation of the hydroxyl group.

Example: D-glucose and L-glucose are mirror images.

Carbohydrate
Organic compounds made of carbon, hydrogen, and oxygen, typically in a 1:2:1 ratio.

Example: Starch and cellulose are carbohydrates.

Enantiomers
Pairs of molecules that are mirror images of each other.

Example: D and L forms of sugars are enantiomers.
