Calcium and Calcium Salts.
Calcium is the most abundant mineral in the body. Bones and teeth contain approx. 99% of calcium. Calcium exists in both plant and animal foods. The best source of calcium is milk. Indian Council of Medical Research (ICMR) recommends 600-800 mg/day of calcium which increases to 1200 mg/day in pregnant and lactating mothers. Inadequate calcium intake for longer duration is responsible for osteop...
متن کاملBioavailability and Solubility of Different Calcium-Salts as a Basis for Calcium Enrichment of Beverages
Background: When usual calcium consumption patterns were analysed most people in the U.S. and Europe consume less than the recommended daily allowance. Supplements and fortified foods offer alternative and additional sources of calcium to traditional food. Calcium carbonate is the most common supplement but it is less soluble in water and, therefore, not suitable for enrichment of beverages. Ne...
متن کاملBile salts and calcium absorption.
1. The study of the effect of bile salts on enhancing calcium absorption in the rachitic chick has been extended to bile salts not present in chick bile, e.g. glycine conjugates and bile alcohol sulphates. 2. Bile and bile salts cause an increase in calcium absorption from sparingly soluble calcium hydrogen phosphate when compared with a suspension of calcium hydrogen phosphate in saline. 3. If...
متن کاملStudies of the Solubility of Calcium Salts
The biological importance of calcium has been recognized since the earliest times, but it has only been comparatively recently, through the stimulus afforded by the growing realization of the close association between some pathological conditions and disturbances of the calcium metabolism of the body, that the element calcium has claimed so much attention and study in biological fields. Being t...
متن کاملSupersaturation Control in Aragonite Synthesis Using Sparingly Dissoluble Calcium Salts as Reactants
Sparingly dissoluble calcium salts were studied as reactants in the synthesis of needlelike precipitated calcium carbonate (PCC). Morphology and aspect ratio of the PCC particle were characterized with SEM. Polymorphs and crystal size were characterized using x-ray diffraction. The counter-ions of the sparingly dissoluble salts influenced growth kinetics of PCC as well as the polymorphs and mor...
