For example, some species hydrolyse came sugar and maltose, and then carry on fermentation at the expense of the simple sugars (hexoses) so formed.
Saccharomyces Marxianus will not hydrolyse maltose, but it does attack cane sugar and ferment the products of hydrolysis.
Fischer next suggested that enzymes can only hydrolyse those sugars which possess a molecular structure in harmony with their own, or to use his ingenious analogy, "the one may be said to fit into the other as a key fits into a lock."
This latter compound may be chlorinated to perchloracetoacrylic chloride (9), from which the corresponding acid (to) is obtained by treatment with water; alkalis hydrolyse the acid to chloroform and dichlormaleic acid (I I).
Heated with acids or alkalis they hydrolyse to acids: RCN + HC1 + 2H 2 O = R COOH NH4C1.
They boil at temperatures somewhat lower than those of the corresponding nitriles; and are stable towards alkalis, but in the presence of mineral acids they readily hydrolyse, forming primary amines and formic acid: RNC+2H 2 O = RNH2+H2C02.
They hydrolyse readily when boiled with solutions of caustic alkalies or mineral acids, yielding the constituent acid and alcohol.
Cocaine in which the benzoyl group is replaced by the cinnamyl group. aand 3-truxillines, named from their isolation from a coca of Truxillo (Peru), are two isomeric alkaloids which hydrolyse to ecgonine, methyl alcohol, and two isomeric acids, the truxillic acids, C18H1604.
