Found in the yeast and in the intestinal juice.

A

INVERTASE OR SUCRASE

25
Bring about in the hydrolysis of sucrose into glucose and fructose.
INVERTASE OR SUCRASE
26
• Also found in yeast and in intestinal juice. • Causes the conversion of maltose into glucose.
MALTASE
27
• Fermenting enzymes causing the conversion of monosaccharides (glucose, fructose) into alcohol and carbon dioxide.
ZYMASE
28
Found in almonds.
EMULSIN
29
Causes the hydrolysis of β-glycosides, thus, amygdalin is hydrolyzed into glucose, benzaldehyde and hydrogen cyanide.
EMULSIN
30
Found in white and black mustard
MYROSIN
31
Hydrolyzes Sinalbin and Sinigrin as well as other glycosides.
MYROSIN
32
Found in the pancreatic juice of animals and in oily seeds.
LIPASE
33
Causes the hydrolysis of fats into glycerin and fatty acids.
LIPASE
34
Splits pectin into pectic acid and methyl alcohol.
PECTASE
35
A lipolytic enzyme capable of digesting dietary fat.
STEAPSIN
36
Obtained from soybeans.
UREASE
37
Used as a laboratory reagent for converting urea to ammonia.
UREASE
38
Found in the gastric juice. • Converts proteins into proteoses and peptones.
PEPSIN
39
Formed when the proenzymes, trypsinogen is acted on by the enterokinase of the intestinal juices.
TRYPSIN
40
Converts proteoses and peptones into polypeptides and amino acids.
TRYPSIN
41
Found in intestinal juices. • Converts proteoses and peptones into amino acids.
