The activities of the two enzymes were co... |
231 | Biochemical aspects of renal ammonia formation in metabolic acidosis. | In omnivorous creatures, the diet is acidogenic, especially as a result of the meat content, which gives rise to phosphoric and sulphuric acids, i.e., to metabolic acidosis. In the short term, metabolic acids are buffered by tissue proteins and bicarbonate (the 'alkali reserve'). In the longer term, acid must be excret... |

235 | Hydroxylation of p-Coumaric acid by illuminated chloroplasts. The role of superoxide. | 1. Chloroplasts isolated from leaves of spinach-beet (Beta vulgaris L. ssp. vulgaris) do not catalyse the hydroxylation of p-coumaric acid in the dark unless a reductant (such as ascorbate, NADH or NADPH) is added. Superoxide dismutase has no effect on this reaction. 2. Illuminated chloroplasts catalyse the hydroxylati... |
