Role of glucose-1-phosphate and glucose-6-phosphate in glycogen synthesis by pigeon liver homogenate (1976)1. 1. Glucose-1-C14, G-6-P-1-C14 and G-1-P-l-C14 have been incubated with a pigeon liver homogenate. Incorporation of C14 into glycogen and CO2 were measured. 2. 2. The relative incorporation of C14 from G-6-P-1-C14 and ...

(1976)Functional micelles of hexadecyl(2-hydroxyethyl)dimethylammonium bromide (I) are better catalysts than hexadecyltrimethylammonium bromide (CTABr) for the alkaline hydrolysis of diethyl and di-n-hexyl p-nitrophenyl phosphate ...

Aromatic nucleophilic substitution in nucleophilic surfactants. Comparison with alkoxide reactions (1976)The reactions of 2,4-dinitrochloro- and fluorobenzene (DNC and DNF) with the alkoxide ions of choline, propargyl alcohol, and 2,2,2-trifluoroethanol give ether intermediates which react readily with hydroxide ion. The ...

(1976)The endogenous protein synthesis of Xenopus laevis and Calyptocephalella caudiverbera oocytes was studied by measuring the incorporation into acid-precipitable material of radioactive amino acids placed in the extracellular ...
-
(1976)First excited singlet and triplet electric dipole polarizabilities are reported. The π polarizability is calculated by means of a modified Rayleigh–Schrödinger perturbation theory and an SCF‐LCAO basis. The σ contribution ...

(1977)The genetic information of Φx 174 genome (genes and intermediate segments) is analyzed in terms of its independent (D1 index) and dependent information (D2 and D3 Markovian indexes), as well as of its ability to generate ...
-
(1977)Long‐acting sulphonamides are highly bound to plasma proteins; the present study deals with the effects of this binding property upon a vitamin A compound also transported by plasma proteins. Sulphamethoxypyridazine was ...
-
(Kluwer Academic Publishers, 1977)The dietary composition of the antarctic fish Notothenia gibberifrons Lönnberg in a depth gradient was studied, from sea level until 200 meters in South Bay, Doumer Island, West Antarctic. The diet of this species varied ...
-
(Springer-Verlag, 1977)High-alumina basalts from seven High-Andean stratovolcanoes (37 °30′S to 41 °S) have major and trace element (including rare earth elements, REE) that are consistent with derivation by partial melting (typically 10-15%) ...
-
(1977)The role of naturally-occurring soil organic matter (SOM) in the translocation of metal ions from parent materials to biological systems is discussed. To explain the movement of essential elements, a hypothesis or model ...
-
(1977)An experimental technique was devised to measure the maximum binding ability (MBA) of any macromolecule having electron donor groups. It is a dialysis technique wherein polymer portions are isolated in dialysis bags and ...
-
(1977)A soluble enzyme preparation from the flavedo of Citrus limonum transforms [1-3H1]neryl pyrophosphate or [1-3H1]geranyl pyrophosphate into β-pinene, sabinene, α-pinene, and limonene. The enzyme has been partially purified ...
