CALCIUM- NUCLEIC ACID COMPLEX AND PRODUCTION THEREOF

摘要

PURPOSE: A process of preparing the titled complex containing a high molecular weight nucleic acid is provided. The high molecular weight nucleic acid being in the complex inhibits precipitation of calcium in the body and thus permits easy absorption of calcium. CONSTITUTION: A calcium-nucleic acid complex contains nucleic acid which is derived from animals, plants and microorganisms and has a molecular weight of 1,000 to 1,000,000. The complex is prepared by the steps of: dissolving a calcium material in a solvent at 20 to 40deg.C for 1 to 3hr; adding the calcium solution to nucleic acid; controlling pH thereof to 4.0 to 7.5 using an alkaline solution; and filtering an insoluble complex.
