Enzymatic Studies on Cereals. (Part XV.)

Studies on Enzymatic Histochemistry

Extraction experiments demonstrated that choline esterase could be removed from microtome sections of tissue with as great facility by 0.9 per cent NaCl as by 30 per cent glycerol. The quantitative distribution of choline esterase through the wall of the pig stomach was studied, and it was found that the epithelial cell region possessed the greatest activity and muscle tissue the least. Pylorus...

Studies on Echinococcosis Xv : Secondary Multilocular Echinococcosis by Intrahepatic Inoculation

[Quantum chemical studies on enzymatic reaction mechanisms].

Computer modeling of enzymes is a valuable complement to experiments. Quantum chemical studies of enzymatic reactions can provide a detailed description of the reaction mechanism and elucidate the roles of various residues in the active site. Different reaction pathways can be analyzed, and their feasibility be established based on calculated energy barriers. In the present thesis, density func...

Studies on the Enzymatic Synthesis of Glutamine.

Theorell (1942) has reported sedimentation and diffusion measurements on peroxidase: our value for S20 (corr.) is about 10% lower than his (3-85 x 10-13) (cf. Cecil & Ogston, 1948), while our value for D20 (corr.) agrees fairly well with his value of 6 84 x 1o-7. Our value for the molecular weight is lower than Theorell's (44,100), but is in agreement with that calculated by Keilin & Hartree (1...

Studies of Gallbladder Function. Xv. Cholesterol in Human Liver Bile.

The subject of bile drainage in the human has been very thoroughly reviewed by Fox (1) in 1928. Numerous papers have appeared, among which may be mentioned those of Walters, Green and Frederickson (2), Ravdin, Johnston, Riegel and Wright (3), and Elman and Graham (4), describing the changes occurring in hepatic bile obtained from patients with surgical drainage after the release of biliary obst...
