D-Fructose

D-Fructose is a naturally occurring monosaccharide with the chemical formula C6H12O6 and a molecular weight of approximately 180.16 g/mol. It is also known as fruit sugar or levulose and is one of the three common dietary monosaccharides, alongside glucose and galactose. D-Fructose is a ketohexose, characterized by a ketone functional group, and commonly exists in cyclic forms called fructofuranose and fructopyranose.

Key chemical and physical properties of D-Fructose include:

Appearance: White crystalline powder

Odor: Odorless

Solubility: Highly soluble in water and soluble in ethanol

Melting point: Around 103 °C (decomposes)

Density: Approximately 1.69 g/cm³

Optical activity: Levorotatory with a specific rotation [α]D between -92° to -93° in aqueous solution

Sweetness: It is one of the sweetest naturally occurring sugars, sweeter than glucose and sucrose

D-Fructose is widely used in the food and beverage industry as a sweetener, often in the form of high-fructose corn syrup or crystalline fructose. It also has applications in pharmaceuticals and biochemical research as an energy source and metabolic substrate.

In summary:

Chemical formula: C6H12O6

White crystalline powder, odorless

Highly water soluble, ketohexose sugar

Used mainly as a sweetener, in food, pharmaceutical, and biochemical applications

This makes D-Fructose an important sugar both nutritionally and industrially.​
