Low-temperature heat capacities of molybdenum tri- and tetrachlorides
(Elsevier, 1975-06)
No thermal anomalies were detected in the heat capacities of MoCl3 and MoCl4 determined by adiabatic calorimetry from 5 to 350 K. The heat capacity Cp(298.15 K), entropy {So(298.15 K) - So(0)}, and the function {Go(298.15 ...
Crystal and molecular structure of 4-amino-4-carboxyl thiapyran
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1975-11)
4-Amino-4-carboxylthiapyran crystallizes in space group P 2 1 / c with a = 10.61, b = 6.55, c = 10.97 Å, β =96.3 °, and Z = 4. The structure was solved by the heavy-atom method, with 897 observed reflections, and refined ...
Preparation of 32P-labeled inositides and their degradation by soluble kidney enzymes
(Elsevier, 1975-07-22)
A method is described for the preparation of radioactive inositol lipids for studies of their enzymic degradation. Kidney cytosol fractions have been used to produce diesteratic cleavage. High voltage electrophoresis at ...
Synthetic inhibitors of glucocerebroside [beta]-glucosidase
(Elsevier, 1975-02)
The glucocerebrosidase of human placenta was studied with various potential inhibitors. Several compounds that resemble the lipoidal product of enzyme action, ceramide, proved to be excellent inhibitors, acting by mixed ...
Low-temperature heat capacities of molybdenum diselenide and ditelluride
(Elsevier, 1975-07)
The low-temperature heat capacities of MoSe2 and MoTe2 have been determined for technological and scientific reasons. Both compounds in their hexagonal form have a lamellar sandwich-layer structure and in confirmation of ...
A theoretical estimate of the energy barriers between stable conformations of the proline dimer
(Wiley Subscription Services, Inc., A Wiley Company, 1975-06)
Semi-empirical energy calculations for an internal Pro-Pro dimer are presented that take into account the nature of the flexibility of the proline ring due to its puckering. Calculations show that three stable conformations ...
On the nature of the iron sulfur cluster in a deuterated algal ferredoxin
(Elsevier, 1975-12-11)
A protonated and a completely deuterated two-iron algal ferredoxin from Synechococcus lividus have been studied by optical, electron paramagnetic resonance, electron-nuclear double resonance, proton magnetic resonance and ...
The effect of proteoglycans on the formation of fibrils from collagen solutions
(Elsevier, 1975)
The precipitation of collagen fibrils from solutions at 37 [deg]C and approximately physiological pH and ionic strength is retarded markedly in the presence of small amounts of proteoglycan monomer (PGS), proteoglycan ...
Activity of prostaglandin E, F, A and B on sphincter, dilator and ciliary muscle preparations of the cat eye
(Elsevier, 1975-02)
Both sphincter and dilator muscle preparations of the cat iris contract to prostaglandins; F2[alpha] and E2 are the most potent and A1 and B1 the least. Ciliary muscle strips relax to PG's provided that the strips are ...
