| Descripción: | The following data were obtained on the decarboxylation pathways of amino acids in some mammal and bird tissue homogenates: 1. PIG KIDNEY AND LIVER: Three preformed amine-like compounds were observed in the kidney and strong disappearance of added serotonin during anaerobic and aerobic incubation (strong conjugases? and monoamine oxidase activities). No significant disappearance of added histamine was found after anaerobic or aerobic incubation. In the liver serotonin disappeared only after aerobic incubation. Free glucose (reacting with the added amines) was present in the liver but not in the kidney. 2. Ox ADRENALS: Two preformed amine-like compounds were present which are not noradrenalin or dopa amine. Absence of conjugases or amine oxidases. 3. GUINEA PIG LIVER; Strong disappearance of added serotonin after anaerobic incubation.
