What Is D-Mannose?

It is divided into two types, α-form and β-form. The Α-form is a methyl group crystal with a melting point of 133 °C; the β-form is an ethyl group with a melting point of 132 °C (decomposition point). Sweet and slightly bitter aftertaste. Soluble in water (250%), insoluble in ethanol (0.4%), insoluble in ether.

Usage

1. Used as a biochemical reagent

2. Used for cell culture and molecular biology

D-(+)-mannose, a simple sugar that has many uses, including:

Glycosylation: D-(+)-mannose is used in the formation of glycan structures and glycosylation.

Protein glycosylation: Mannose is a critical sugar for protein glycosylation.

Alternative energy source: The brain can use mannose as an alternative energy source.

Prebiotic: Some studies suggest that D-mannose may help the body by stimulating the growth of “good” bacteria in the digestive system.

Immune system: Mannose has demonstrated benefits for the immune system, being active against metabolic syndrome, diabetes, intestinal diseases, urinary tract infections, and other conditions.

Food industry: Mannose is used as a texture modifier in ice creams, salad dressings, and processed fruits.

Cell culture and microbiology: D-(+)-mannose is suitable for cell culture and microbiology.

Humectant: D-(+)-mannose is used as a humectant.

D-(+)-mannose is a white to almost white powder or crystal. It is recommended to store it in a cool, dark place at a temperature below 15°C.
