The experiment to be described in this paper relates to the influence which the addition of magnesium salts and of magnesium salts plus phosphates to the diet may exert upon calcium metabolism. They may also be interpreted as throwing some light upon the general problem of the mutual relationships which exist among the mineral constituents of the diet, considered from the standpoint of animal n...

As phosphate derivatives form such important intermediates between the functioning of tissues and the metabolism which supports function, we decided to investigate the levels of certain phosphates in brain slices before and during metabolism in vitro. Investigation of this type appeared all the more necessary because there is now an extremely interesting group of observations on the levels of p...

Although milk salts are classified as micronutrients, they strongly affect the behaviour of proteins and physical stability dairy products. This review focuses on heat-induced changes in salts, with particular emphasis salt speciation, precipitation association proteins. In other liquids at neutral pH, heating results calcium phosphates. These precipitates may become stabilised by caseins casei...

• The importance of potassium and various chlorides in the pathogenesis of several experimental cardiac necroses was first suggested by the observation that all the potassium salts (phosphates, sulfates, chloride, etc.) and all the chlorides (of magnesium, potassium, ammonium, etc.) tested were effective in preventing the myocardial lesions, while no other salts had such an effect. In a previou...

Solubil ity is one of the most important properties of calcium phosphate salts. It is the solubil ity that determines the direction of many reactions that involve calcium phosphates such as dissolution, precipitation, hydrolysis, and phase transformation. Calcium phosphate solubil ity also plays a maior role in biological processes that involve formation and resorption ol' hard tissues as well ...

The usual method employed in determining the acidity of milk is to add a few drops of a solution of phenolphthalein as indicator to 100 cc. of milk and then titrate with 6 NaOH. By the use of this method it is found that 100 cc. of milk, when strictly fresh, will require the addition of 15 to 20 cc. of the alkali in order to produce a faint but permanent pink coloration. The acidity of fresh mi...

Abstract This study was done to identify some characteristics of chemical, physical, and the concentrations nutritious salts nitrate, phosphates in groundwater on six wells selected district Al-Shinafiyah during period from June August 2022. The results obtained for temperatures were almost equal between with rates ranging 23-25 C°. pH values ranged (7-7.23). Electrical conductivity (4250-6350)...
