is apparently 50% regeneration; (b) Ama. is shifted about 8 m,u. towards shorter wavelengths. 2. This result has been obtained with frog, rat and ox rhodopsin, and the amount of regeneration is, within the experimental error, 50%. 3. A working hypothesis concerning the structure of the rhodopsin chromophore and the mechanism of its photodecomposition is presented. One of us (F. D. C.) participated in this work as a holder of a New Zealand National Research Scholarship. We are indebted to the Medical Research Council and the Ministry of Food for a grant.

The role of aneurin in the nutrition of Tetrahymena geleii.

Recent studies of intermediary metabolism emphasize the indispensability of carboxylation-decarboxylation reactions in mediating changes in length of carbon chain in a number of key compounds of the metabolic pool (Ochoa, 1951). That aneurin is needed for at least one such reaction-the decarboxylation of pyruvate-can be inferred from the observations that aneurin-deficient organisms accumulate ...

The localization of aneurin pyrophosphatase in the brain.

Vitamin B1 is nearly exclusively present in animal tissues as aneurin pyrophosphate (Ochoa and Peters, 1938). The vitamin is first converted to aneurin pyrophosphate by the tissues and in this form it enables the oxidative decarboxylation of pyruvic acid to take place allowing glucose metabolism to go beyond the pyruvate stage (Banga, Ochoa, and Peters, 1939). It has been shown more recently th...

The Thermal Destruction of Vitamin B1 3. THE INFLUENCE OF COPPER ON THE RATE OF DESTRUCTION OF ANEURIN IN BUFFER SOLUTIONS

The first recorded statement concerning the influence of copper on the rate of destruction of aneurin is that of Booth (1943), who claims that aneurin is destroyed more rapidly in the presence of Cu than in its absence. Work in these laboratories on the behaviour of aneurin during the manufacture ofyeast extract which contained significant amounts of Cu suggested that, perhaps, this metal was n...

The Effect of Economic Sanctions on Iran's Formal and Informal Economy

Economic infrastructure plays an important role in the economic growth of developing countries. An increase in the informal sector of the economy will lead to lower tax bases, less production of basic public infrastructure and public services, and ultimately lower economic growth. As a developing country in need of economic growth, Iran is currently embroiled in sanctions in various dimensions,...
