I fondamenti chimici e chimico-fisici della microdeterminazione colorimetrica dell'acido fosforico mediante l'azzurro di molibdeno

Abstract: I f o n d a m e n t i chimici e ehimieo-fisiei della m i e r o d e t e r m i n a z i o n e c o l o r i m e t r i c a d e l r a c i d o fosforieo m e d i a n t e r a z z u r r o di molibdeno.* I. Metodi di dosagglo delrione foslorieo. Di Y. Zambotti, (Eingelang~ am 8. Augus~ 1938.) Numerosi sono i metodi di determinazione dell'ione fosforico in materiale biologico elaborati nell'ultimo ventennio. Li possiamo suddividere in quattro gruppi: metodi gravimetriei, vohmetriei, nefelometrici e colorimetrici.A. Meto… Show more

“…ATP-ase activitj' was measured by determining the release of inorganic phosphate in a reaction medium containing ATP, mitochondrial suspension and other addition as indicated in the single experiments. The reaction was stopped hy addition of PCA, to make a final concentration of 5 per cent, the precipitated material centrifuged off, and inorganic phosphate was determined in an aliquot of the clear svipernatant solution hy the method of Briggs (2), in the conditions proposed by Zamhotti (19), and adapted for a final volume of 9 milliliters. In each experiment, all the data were obtained from duplicate samples whose values always agreed within 5 per cent; the values of phosphate split from ATP were ohtained by subtracting the phosphate content of a zero minute reaction time sample.…”
