On the contrary, with the development of new methods, the organic chemist obtains the results that he needs for a first orientation on a compound, more quickly and more reliably than ever before.

متن کاملThe Accumulation of Electrolytes Vii. Organic Electrolytes
I t has been suggested that potassium may enter Valonia chiefly as KOH which reacts with an organic acid HA in the sap to form KA, after which A is exchanged for chloride so that potassium accumulates as'KC1. This is not contradicted by any known facts and it is supported by a variety of evidence; inasmuch as this has recently been discussed I it need not be cited here. Other cations may act si...
متن کاملSome Biochemical and Electrophoretic Studies on Purified Prothrombin , Factor VII (
S TUDIES of the chemical nature of prothrombin have indicated a glycoprotein structure.2 Data obtained on purified bovine prothrombin have shown the reducing sugar content to be approximately 5 per cent, based on a reference standard of galactose and mannose.35 Laki et al.5 reported a value of 6.5 per cent in terms of glucose, and 1.6 to 1.7 per cent hexosamine. Alexander6 and colleagues observ...
متن کاملStudies on an antibiotic, albocycline VII. Minor components of albocycline.
As an approach to the search for new potentially useful macrolide antibiotics, we explored the minor components of albocycline (ALB) from the culture broth of Streptomyces bruneogriseus. Eight minor components were isolated and their structures were confirmed as 1 approximately 8. Unexpectedly, they were not glycosidic compounds but only oxidation or reduction products of ALB. Three or four of ...
