Fructose, an example of a ketose. Fructose (also levulose or laevulose) is a simple reducing Sugar ( Monosaccharide) found in many foods and is one of the three The ketone group is the double-
bonded oxygen.

A ketose is a sugar containing one ketone group per molecule. Sugar is a class of edible Crystalline substances mainly Sucrose, Lactose, and Fructose. A ketone (pronounced as key tone) is either the Functional group characterized by a Carbonyl group (O=C linked to two other Carbon atoms or In Chemistry, a molecule is defined as a sufficiently stable electrically neutral group of at least two Atoms in a definite arrangement held together by

With 3 carbon atoms, dihydroxyacetone is the simplest of all ketoses and is the only one having no optical activity. Carbon (kɑɹbən is a Chemical element with the symbol C and its Atomic number is 6 Dihydroxyacetone (also known as DHA) is a simple Carbohydrate that is primarily used as an ingredient in Sunless tanning products Optical rotation or optical activity is the rotation of linearly polarized Light as it travels through certain materials Ketoses can isomerize into an aldose when the carbonyl group is located at the end of the molecule. This article is about the chemical concept For "isomerism" of atomic nuclei see Nuclear isomer. An aldose is a Monosaccharide (a simple Sugar) containing one Aldehyde group per Molecule and having a Chemical formula of the Such ketoses are reducing sugars.

List of ketoses

• Trioses: dihydroxyacetone
• Tetroses: erythrulose
• Pentoses: ribulose, xylulose
• Hexoses: fructose, psicose, sorbose, tagatose

Qualitative reaction

General qualitative reaction for ketoses is Seliwanoff's test. A triose is a Monosaccharide containing three Carbon Atoms There are only two trioses an aldotriose ( Glyceraldehyde) and a Dihydroxyacetone (also known as DHA) is a simple Carbohydrate that is primarily used as an ingredient in Sunless tanning products A tetrose is a Monosaccharide with 4 Carbon atoms They either have an Aldehyde Functional group in position 1 ( aldotetroses) D-Erythrulose (also known as erythrulose) is a Tetrose Carbohydrate with the chemical formula C 4 H 8 A pentose is a Monosaccharide with five Carbon Atoms They either have an Aldehyde Functional group in position 1 ( aldopentoses Ribulose is a Ketopentose &mdash a Monosaccharide containing five Carbon Atoms and including a Ketone Functional group Xylulose is a Ketopentose, a Monosaccharide containing five Carbon Atoms and including a Ketone Functional group. In Organic chemistry, a hexose is a Monosaccharide with six Carbon atoms having the Chemical formula C6H12O6 Fructose (also levulose or laevulose) is a simple reducing Sugar ( Monosaccharide) found in many foods and is one of the three D-Psicose (D-ribo-2-hexulose C 6 H 12 O 6 is an ultralow-energy Monosaccharide Sugar. Sorbose is a Ketose belonging to the group of Sugars known as Monosaccharides The commercial production of Vitamin C ( Ascorbic acid Tagatose is a Functional sweetener. It is a naturally occurring Monosaccharide, specifically a Hexose. Seliwanoff’s test is utilized to differentiate between Aldose and Ketose Sugars The reagents consist of Resorcinol and conc
