PARTIAL CHARACTERIZATION OF LIPASE FROM COCOA BEANS (Theobroma cacao. L.) OF CLONE PBC 159
ABSTRACT A study was caffied out to characterize the cocoa lipase from cocoa beans (Theobroma cacao, L.) of clone PBC 159. The optimum temperature of cocoa lipase was 30-40 .C and the pH optimum was 7.0-8.0. The moleculer weight of the lipase enzyme was in between 45-66 kOa. The results indicate tha...

description | ABSTRACT
A study was caffied out to characterize the cocoa lipase from cocoa beans (Theobroma cacao, L.) of clone
PBC 159. The optimum temperature of cocoa lipase was 30-40 .C and the pH optimum was 7.0-8.0. The moleculer
weight of the lipase enzyme was in between 45-66 kOa. The results indicate that Kmvalue for cocoa bean lipase was
2.63 mM, when trimyristin was used as a substrate. The incubation of cocoa bean lipase with triolein and tributyrin
(as substrate) yielded Kmof 11.24 and 35.71 mM, respectively. The Vmaxvalue obtained from the incubation of the
lipase with a wide range of substrates, including tributyrin, trimyristin and triolein, are expressed as pmole
acidlmin/mg protein for cocoa lipase. Vmax values decreased with the increase in the triacylglycerol chain-length, with
Vmax values of 27.78, 13.16 and 11.63 pmole acidlmin/mg protein when incubated with tributyrin, trimyristin and
triolein, respectively. Inhibition of lipase occurred in the presence of diisopropyl fIourophosphate, Nbromosuccinimide
and 5,5-dithiobis-(-2-nitrobenzoic acid).
