NON-PROTOPLASMIC CELL CONTENTS 103 
INuULASE, found in plants of the Daisy and Bluebell families, 
etc., transforms inulin to levulose. 
ZyMASE, found in yeast, hydrolyzes glucose (dextrose and 
levulose) to alcohol and carbon dioxide according to the follow- 
ing equation: CsH»2Os = 2C,H;OH + 2COr. 
2. Fat AND O1L ENZYME: 
Lipase splits up fats and oils into fatty acids and glycerin. 
It is found in various mildews, molds and numerous oily seeds 
and other fatty-oil storage regions of higher plants. 
3. PROTEINACEOUS ENZYMES: 
PEpsIN converts proteids into proteoses and peptones. 
Trypsin, found in yeast and other fungi, as Boletus edulis, 
Amanita spp., etc., resolves proteins to peptones and amino-acids. 
BROMELW, found in the fruit of the Pineapple, and PAPAYIN 
(Papain), found in the latex of the fruit of the Papaw, act 
similarly to trypsin. 
-Nepentuin, found in the pitchers of Nepenthes species, acts 
similarly to pepsin. 
4, GiucosipE ENZYMES: 
Emutsin (synaptase), found in the seeds of the Bitter Almond, 
Cherry Laurel leaves, in the barks of the Wild Black Cherry and 
Choke Cherry and in other Rosaceous plant parts, in Manihot 
utilissima, Polygala species, etc., hydrolyzes the glucoside present 
(either amygdalin or ]-mandelonitrile glucoside) to hydrocyanic 
acid, benzaldehyde and glucose. 
Myrostn (myronase), found in the seeds of the black mustard 
(Brassica nigra) and other members of the Crucifere, converts 
the glucoside, sinigrin, into allyl-iso-sulphocyanide and glucose. 
RuamnaseE, found in Alder Buckthorn (Rhamnus Frangula) 
and probably other species of Rhamnus, hydrolyzes the anthra- 
glucoside frangulin to rhamnose and emodin. 
GAULTHERASE, found in Wintergreen (Gaultheria procumbens) 
and other Ericaceous plants, resolves the glucoside, gaultherin, 
to methyl-salicylate and glucose. 
5. Orcanic Actp ENZYMES: 
REDUCTASE of yeast decomposes lactic acid to pyrotartaric 
acid and hydrogen. It also decomposes formic acid into carbon 
dioxide and hydrogen. -
