Dictionary » H » Hydrolysis HydrolysisDefinition noun (chemistry) (1) A chemical reaction in which the interaction of a compound with water results in the decomposition of that compound. (2) A chemical reaction wherein a water molecule (HOH) and a reactant exchange functional groups resulting in two end products, one containing the hydrogen cation (H) and the other the hydroxyl anion (OH). An example is the chemical reaction of water with the ions of salt resulting in the formation of an acid and a base, one or both of which is only slightly dissociated. (3) The process of splitting a compound into fragments with the addition of water; a kind of reaction that is used to break down polymers into simpler units, e.g. starch into glucose.
Word origin: Gk. hydor = water + lyein = to loosen, dissolve.

Results from our forumHelp! "Unknown Bacteria" I have no idea where to look =THello Stephanie, M. Luteus does not always give a positive for Gelatin hydrolysis and to make matters worse it can return both results for casein hydrolysis as well. As far as direction to point you in, A litmus milk test would really be the ideal way to get ...
