The first step is searching out a flower to pick up some nectar. Nectar is a mixture of sugar and water. Specifically, the sugar in nectar used to make honey is sucrose, a disaccharide (see Biochemistry ). A honeybee produces enzymes in its body that Ctm break down the sucrose into monosaccharides, fructose, and glucose as well as gluconic acid. These sugars are the primary constituents of honey. Most of the water evaporates, which is what makes honey so viscous and sticky. 

Disaccharides, the simplest polysaccharides, are formed by condensation of two monosaccharides with the elimination of water. Only three are of importance in biochemistry maltose (10.19a),... 

Insect muscle utilizes the Meyerhof sequence only as far as pyruvate, and the NADH produced during triosephosphate oxidation seems to be reoxidized by the reduction of dihydroxyacetone phosphate to glycerophosphate (Chance and Sacktor, 1958). The major sugar in the plasma is a,a-trehalose, a disaccharide of glucose, and it plays a major part in the glucose transport system of insects (Wyatt and Kalf, 1957). For a review of insect biochemistry, see Goodwin (1965).
