colipase


Also found in: Wikipedia.

co·lip·ase

(kō'lip-ās),
A small protein in pancreatic juice essential for the efficient action of pancreatic lipase. This cofactor inhibits the surface denaturation of the lipase.
[co- + lipase]

co·lip·ase

(kō'lip-ās)
A small protein in pancreatic juice that is essential for the efficient action of pancreatic lipase.

They are used as energy source, cell membrane recovery, hormones among other functions (Hide et al., 1992); however, the hydrolysis of lipids is highly complex by lipases due the interface water-lipid that implies the necessity for the enzyme to join to colipase and bile salt to break the ester bonds (Gjellesvik et al., 1992).

Olive oil was utilised as substrate in sodium taurodeoxicolate 6mM, NaCl 0.15M, Ca[Cl.sub.2] 1mM, Tris (hydroxymethyl) aminomethane buffer 0.2mol [L.sup.-1] pH 8.0 and partially purified broiler colipase (BROCKMAN, 1981).
(2) However, contemporary lipase assays now contain colipase and bile salts that increase the analytical sensitivity of lipase assays.
All four experimental methods (experimental reagents from Sentinel) contained colipase, but differed from one another in stabilizing proteins and in the size of substrate micelles: two methods contained protein (0.3 g/L) and micelles with either a 250-nn (P250) or 400-nn (P400 method) diameter, respectively; the two methods without added protein used micelles with either a 250-nn (NP250) or 400-nn (NP400) diameter.
Serum lipase activity increased in all our patients without a parallel increase in serum amylase titers; the combination of accurate clinical, biochemical, and instrumental study of these patients allowed us to exclude the possibility of a normoamylasemic pancreatic injury, and the presence of appropriate concentrations of bile salts and colipase in the reagent favors a full and specific action of lipase assay, at the same time inhibiting serum esterase (8).
In the small intestine lipolysis is completed by pancreatic lipase acting with colipase as cofactor and absorption of lipolytic products starts.
