SOME CURIOUS CARBOHYDRATES 



The differences between the sweets extracted 

 from the sugar cane and those taken from the 

 sorghum are very obvious and tangible. 



One plant supplies a juice that when boiled 

 and evaporated and refined gives a fine granular 

 product familiar to everyone as sugar. 



The juice of the other plant, somewhat sim- 

 ilarly treated, constitutes a sirup of varying 

 color, which is exceedingly sweet and palatable, 

 but which cannot be reduced to a granular con- 

 dition in which it could by any chance be mis- 

 taken for cane sugar. Yet the chemist tells us 

 that the sugar content of the juices of these 

 plants is in each case a compound made up ex- 

 clusively of three elements carbon, hydrogen, 

 and oxygen and that the differences observed 

 are due to modifications in the proportions in 

 which the different elements are compounded. 



It appears that sugar of the glucose type, as 

 represented in the sirup of the sorghum, is a 

 much more simple compound than cane sugar. 



The glucose has only six atoms of carbon 

 while cane sugar has eighteen; it has twelve
