Journal ArticleDOI
TL;DR: The analysis outlined below’ is designed to enable one to attain an insight into the composition of proteins by methods which require but small amounts of material and yield approximately quantitative results, indicating the nature of all the nitrogenous products yielded by complete acid hydrolysis.

Journal ArticleDOI
TL;DR: Dogfish were fed by a tube with chopped, coagulated beef, and killed after 6, 12, 24, 48 and 72 hours as mentioned in this paper, and stomach determinations were made of insoluble nitrogen, soluble nitrogen, (c) soluble nitrogen in amino form,1 and (d) soluble amino form after complete hydrolysis.

Journal ArticleDOI
TL;DR: Neubauer et al. as mentioned in this paper constructed a diagram to represent diagrammatically the catabolism of tyrosine and of phenylalanine in the normal organism and showed that not only phenyl-alanine and tyrosines but also homogentisic acid yield aceto-acetic acid and acetone on perfusion through an excised normal liver.


Journal ArticleDOI
TL;DR: It was found and reported that a solution containing copper sulphate, sodium carbonate, and sodium citrate is more sensitive as a test for sugars than is Fehling’s fluid, and unlike this latter solution, is not reduced by uric acid, chloroform, or the simple aldehydes.


Journal ArticleDOI
TL;DR: This study deals with the cultural properties, the products of growth, the pathogenicity, and the toxicity, of two strains of Proteus vulgaris, Hauser.



Journal ArticleDOI
TL;DR: The olive tubercle organism, Bacterium Savastanoi, studied and named by him, forms an acid when grown aerobically in the presence of certain sugars, and an abundant, white, cauliflower-like mass developed that under a hand lens could be seen to consist of aggregates of fine needles.





Journal ArticleDOI
TL;DR: The common saprophytic molds were found to have the power of utilizing a surprisingly large variety of chemical substances as sources of carbon and nitrogen.
