Fructose
The fructose is a Monosaccharide (simple Sucre non-hydrolysable) of the group of the Cétose S, which one finds in abundance in the Fruit S and the Miel. It is a Hexose (sugar with 6 carbons) and presents the same empirical formula as its Isomère S, in particular the Glucose: C6H12O6.
Its semi-developed formula is CH2OH-CHOH-CHOH-CHOH-CO-CH2OH or C4H9O4-CO-CH2OH if one wants to reveal his function Cétone. It rather has tendency to cycliser in its form Furanose (cycle with 4 carbons and 1 oxygen) than in its form Pyranose (cycle with 5 carbons and 1 oxygen).
It is the monomer of the Inuline. It has also a To be able sweetening higher than the Saccharose, which is the Sucre of reference what explains why its use is recommended in certain modes.
When it is in its form D, the optical activity of the fructose is laevogyrous of -93 degrees, of or its other name: levulose.
