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.
