Citric Acid and Bone Metabolism
From the sedimentation and diffusion constant values obtained in a solution containing 1 g./ 100 ml. H substance, and using the determined value of the partial specific volume, the molecular weight was calculated from the usual equation (Svedberg & Pedersen, 1940) giving a value of 320 000. From the same data the frictional ratio f/fo obtained was 4-2. This corresponds to an axial ratio of > 10...
متن کاملCitric acid and calcium metabolism.
Recently there has been increasing realisation of tile important part played by citric acid in the body’s metabolism. Thus administration of pyruvic acid, the intermediate metabolite common to the utilisation of carbohydrate, protein and perhaps fat, causes increased urinary excretion of citrate. Many tissues can form citrate by condensation of pyruvate and oxalacetate followed by reduction, an...
متن کاملCitric Acid Metabolism in Carcinogenesis and Its
Previous studies on the calcium metabolism of epidermis undergoing carcinogenesis (@2,10, 11) have suggested the possibility that the action of one or more calcium-binding substances may ac count for the decreased calcium content in hyper plastic epidermis and in a squamous-cell carcinoma. The present investigation has been devoted to a study, in normal and cancerous tissues of the mouse, of th...
متن کاملCitric acid metabolism in the bovine rumen.
Rumen microorganisms rapidly metabolize citric acid to carbon dioxide and acetic acid. The rate of metabolism varied between 0.00008 and 0.76 mumoles per g per min, the rate becoming higher as the citric acid concentration increased. The addition of potassium chloride to rumen contents decreased the rate of utilization. The results indicate that dietary citric acid is unlikely to accumulate in ...
متن کاملSome Aspects of Citric Acid Metabolism*
In addition to its presence in milk (9) and urine (1) citric acid has, within the past few years, been found in many other body fluids including sweat (12), cerebrospinal fluid (2), aqueous humor (7), follicular fluid (14), and blood (3). Apparently, saliva is the only body fluid tested in which citrate has not been detected.l Although citric acid appears to be so generally distributed and is e...
