ANOMALIES IN THE ABSORPTION SPECTRUM AND BLEACHING KINETICS OF VISUAL PURPLE.

摘要: Visual purple from winter frogs shows an intermediate yellow color during bleaching by light; summer extractions do not. This seasonal effect can be duplicated variations in the hydrogen ion concentration and temperature of solutions. Increasing pH approximates condition, while decreasing condition. Temperature has no on alkaline solutions but greatly influences acid At low temperatures add resembles at higher it A photic decomposition product frog retinal is acid-base indicator: colorless solution. Its not dependent upon light. The visual does change under illumination, nor there a difference extractions. Bile salt are usually slightly acid. conflicting results past workers regarding appearance "visual yellow" may due to variation with its differences temperature, or presence base It also possible that vitamin factor variation. bile salts solution, extracted frogs, follows kinetics first order reaction. conform kinetics. Photic alkaline, equation. Acid, appear second equation, this probably artefact interference yellow.
