hydrolysis

 [hi-drol´ĭsis] (pl. hydrol´yses)
the cleavage of a compound by the addition of water, the hydroxyl group being incorporated in one fragment and the hydrogen atom in the other. adj., adj hydrolyt´ic.

hy·drol·y·sis

(hī-drol'i-sis),
A chemical process whereby a compound is cleaved into two or more simpler compounds with the uptake of the H and OH parts of a water molecule on either side of the chemical bond cleaved; hydrolysis is effected by the action of acids, alkalies, or enzymes. Compare: hydration.
Synonym(s): hydrolytic cleavage
[hydro- + G. lysis, dissolution]

hydrolysis

Splitting of a compound into two parts by the addition of water (H2O), the hydrogen atom (H) joining to one part and the hydroxyl group (OH) joining to the other. Hydrolysis is usually effected by a hydrolytic ENZYME.

hydrolysis

a chemical reaction in which large molecules are broken down by the addition of water. For example, fat to fatty acids and glycerol, MALTOSE to glucose, DIPEPTIDE to two amino acids. The reactions are usually enzymically activated. Compare CONDENSATION REACTION.

hy·drol·y·sis

(hī-drol'i-sis)
1. Process by which water slowly penetrates suture filaments and breaks down the suture's polymer chain; hydroxylation produces less tissue reaction.
2. Chemical process in which compound is cloven into two or more simpler compounds; effected by action of acids, alkalis, or enzymes.
