Ketose

Ketose (pronounced: kee-tohs) is a type of monosaccharide that contains a ketone group. The term is derived from the Greek word "ketos", meaning "horn", due to the structure of the ketone group.

Etymology

The term "ketose" was first used in the late 19th century and is derived from the Greek word "ketos", which means "horn". This is in reference to the structure of the ketone group, which resembles a horn.

Definition

A ketose is a type of monosaccharide, which is a simple sugar. Unlike aldose sugars, which contain an aldehyde group, ketoses contain a ketone group. This group consists of a carbon atom double-bonded to an oxygen atom and bonded to two other carbon atoms.

Examples

Examples of ketoses include fructose, the most common ketose, which is found in many fruits and honey, and psicose, a rare sugar that is used as a low-calorie sweetener.
