  Supplemental Enzymes
Lactase or beta-galactosidase is an enzyme that is derived from the fungus Kluyveromyces lactis (formerly known as Saccharomyces lactis) or from the fungus Aspergillus oryzae.
Lactase hydrolyzes the lactose beta-D-galactoside linkage, yielding D-galactose and D-glucose.
Trypsin hydrolyzes proteins to oligopeptides, amylase hydrolyzes starch to oligosaccharides and the disaccharide maltose, and lipase hydrolyzes triglycerides to fatty acids and glycerol.

 Food Product Design: Understanding Enzyme Function in Bakery Foods   (Site not responding. Last check: 2007-10-08)
Because starch exists as a tightly packed granule, amylases must act upon starch granules that are damaged (as many are during flour milling) or on granules that have been gelatinized by moisture and heat (such as when a dough is mixed and baked).
Proteases hydrolyze the peptide bond between the amino group of one amino acid and the carboxyl group of the next amino acid in a protein.
If the protease is allowed to hydrolyze a portion of a dough early in the process -- added to the sponge of white pan bread, for example -- it will reduce the mixing time necessary to develop the dough.

Senescence marker protein-30 is a unique enzyme that hydrolyzes diisopropyl phosphorofluoridate in the liver.
Despite the sequence similarity between SMP30 and a serum paraoxonase (PON), the inability of SMP30 to hydrolyze PON-specific substrates such as paraoxon, dihydrocoumarin, gamma-nonalactone, and delta-dodecanolactone indicate that SMP30 is distinct from the PON family.

The case is completely different if the cation is the conjugate acid of a weak base, or if the cation itself can form a complex ion with water.
The same type of reasoning applies here, if the anion is the conjugate base of a strong acid, no hydrolysis will be observed, but if the anion is the conjugate base of a weak acid, hydrolysis will take place.
In the case of NH Cl, now the Cl anion is not hydrolyzing, but NH is hydrolyzing according to the previously shown equation.
