The Amino Acid Composition of Crystalline Pepsin
The amino acid composition of twice recrystallized pepsin (Worthington Biochemical Corporation) has been determined chromatographically on columns of Amberlite IR 120 resin. The results of the analyses obtained on four different preparations indicate a close agreement in their amino acid composition. Pepsin is unique in that it has a great predominance of acidic amino acids over basic ones. Mor...
متن کاملEfficient one-pot synthesis of pyrazoles catalyzed by nano-crystalline solid acid catalyst
An efficient and green protocol for the synthesis of pyrazoles derivatives by one-pot reaction of different 1,3-dicarbonyl compounds with hydrazines/hydrazides has been developed using nano-sulfated zirconia, nano-structured ZnO, nano-g-alumina and nano-ZSM-5 zeolites, as the catalyst. The optical properties of the nano-structured catalysts and organic molecules were studied. The advantages of ...

متن کاملA crystalline bean seed protein in combination with phytic acid.
A protein combined with phytic acid has been extracted from the dried seeds of Phaseolus vulgaris, variety Great Northern, by the following method. &traction-l00 gm. of bean flour were stirred wit,h 100 ml. of N NaCl, followed by 800 ml. of water. The suspension was centrifuged and the sediment discarded. The pH of the turbid supernatant solution was lowered to 4.6 with about 7.0 ml. of N HCl, ...
