Comparative study of human intestinal esterase and hepatic esterase for these properties and substrate specificity

Specificity and properties of wheat-germ esterase.

Plant sterol and stanol substrate specificity of pancreatic cholesterol esterase.

Consumption of plant sterols or stanols (collectively referred to as phytosterols) and their esters results in decreased low-density lipoprotein cholesterol, which is associated with decreased atherosclerotic risk. The mechanisms by which phytosterols impart their effects, however, are incompletely characterized. The objective of the present study is to determine if pancreatic cholesterol ester...

Pig liver esterase catalyzed hydrolysis: substrate specificity and stereoselectivity

In order to gain a more detailed insight into the relationship between substrate structure and the stereoselectivity of the enzyme pig liver esterase (E.C. 3.1.1 .I .) a large series of mainly meso and prochiral diesters with an open chain or a cyclic structure has been studied and evaluated. Results obtained with 3substituted cyclopropane-l,2-dicarboxylates are incompatible with the three-dime...

Esterase substrate specificity in the testis of the growing mouse

The age distribution of esterases in the interstitial cell of the mouse testis was studied between birth and the end of the tenth week of postnatal life by using the substrates O-acetyl-s-bromoindoxyl, a-naphthyl acetate, naphthol AS acetate, naphthol AS-LC acetate, and naphthol AS-D acetate. With indoxyl acetate, esterase activity is prominent at birth and wanes over the first 2 weeks of postn...

a comparative study of bilingual schools and language institutes: examining iranian efl students’ knowledge of listening, reading grammar and vocabulary

هدف از پژوهش حاضر مقایسه زبان آموزان مدارس دوزبانه و موسسات آموزش زبان انگلیسی به منظور تعیین هر گونه تفاوت معنادار در مهارت های درک مطلب، درک شنیداری، دانش دستوری و دانش واژگان است. اطلاعات لازم برای این پژوهش از مجموعه 197 نفر دانش آموز پسر در مدارس دوزبانه و موسسات آموزش زبان جمع آوری شده است. تمامی شرکت کنندگان به مدت چهار الی پنج سال در کلاس های زبان انگلیسی شرکت کرده اند. به منظور جمع آور...
