Dulcite is another of the hexahydric alcohols, and is found 

 in a manna from Madagascar. It is made artificially from 

 lactose or galactose by treating them with nascent 

 hydrogen. It oxidizes to mucic acid. 



Sorbite occurs in mountain-ash berries. With one 

 molecule of water it forms small crystals which dissolve 

 readily in water. 



Asparagine is the monamide of aspartic or amidosuccinic 

 acid. It occurs in many plants (asparagus, beetroot, peas, 

 beans, etc.). It may be crystallized from the pressed 

 juice in rhombic prisms + iH 2 0. It ferments in the 

 presence of albuminoids to ammonium succinate. There 

 are laevo and dextro varieties. 



Inosite (muscle-sugar) is a crystallizable substance, with 

 the same empirical formula as glucose, but it is not a 

 carbohydrate but a hexahydric phenol of the benzene 

 series. It is also found in unripe peas and beans.

Adonite, C 5 H 7 (OH) 5 is a pentite (from Adonis vernalis). 



Salicin (C 18 H 18 7 ) and Coniferin (C 16 H 22 8 '2H 2 0) are 

 glucosides.
