Hexoses (heks-o 1 '-sez) [e£ac, six]. The aldehyd or

 They are formed by the hvdrolytic decomposition of 

 all disaccharids and polysaccharides when they are 

 bailed with dilute acids, or acted upon by ferments. 

 They possess feeble reducing-power. They precipitate 

 cuprous oxid from warm alkaline cupric solutions, one 

 molecule of hexose precipitating about five atoms of 

 copper. This is the basis of the method for the vol- 

 umetric estimation of glucose by means of Fehling's 

 solution. When exposed to Schizomycetes the hexoses 

 readily undergo fermentation. See Carbohydrates,
