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.
[hydro- + G. lysis, dissolution]

While most researchers have used either alkali treatment or silane treatment or acid hydrolysis individually, it is necessary to attempt using the three methods of treatment in combination, since the mechanisms by which they affect natural fibres are completely different.
First, cellulose fibers were isolated from ATW bagasse fibers by acid hydrolysis and alkaline extraction [2, 24]: briefly, 1 g of ATW bagasse was mechanically dispersed in 19 mL of boiling [H.sub.2]S[O.sub.4] solution (1% vol.) for 1h and subsequently washed with distilled water; then 1 g of the above fibers was mechanically mixed with 10 mL of NaClO solution at room temperature (3.5 vol.%) until reaching a pH of ~9.2 and washed with distilled water until reaching a pH of ~7.
