چکیده انگلیسی
Ascorbic acid (AA—Vitamin C) plays a vital role in human body to preserve optimal health. However, high intake may cause the formation of pathological calcium oxalate stones. Calcium oxalate and calcium phosphates are the major crystalline constituents of the urinary calculi and commonly found together. The effect of AA on the crystallization of calcium phosphate was studied in gel matrix under physiological conditions. Calcium phosphates such as hydroxyapatite (HAp), brushite (DCPD) and calcium oxalate dihydrate (COD—Weddellite) were found to crystallize simultaneously in the gel matrix. The formation of HAp is accelerated by AA. A possible reaction scheme for the formation of COD by the metal induced conversion of AA is proposed.
