Abstract
A method for improving the stability of amino acid-metal complexes or chelates and enhancing the uptake of these complexes into biological tissues. This method comprises forming the metal complexes with amino acids or hydrolyzed proteins and incorporating into them a buffer system which controls the pH of the complex and its surrounding media. This uptake is accomplished by the system of amino acid active transport into the blood stream from which the complex is then carried throughout the entire body.
Claims16
A stabilized metal proteinate for enhancing the uptake of essential minerals into warm blooded animals comprising a metal coordination complex between a metal ion selected from the group consisting of iron, copper, zinc, manganese, cobalt, chromium, calcium, magnesium and vanadium, and an amino acid selected from group consisting of glycine, alanine, valine, leucine, isoleucine, phenylalanine, tyrosine, tryptophan, serine, threonine, aspartic acid, glutamic acid, lysine, arginine, histidine, cystine, cysteine, methionine, proline, hydroxyproline and mixtures thereof, the proteins made up from said amino acids and hydrolysis products of such proteins in a molar ratio of between two and sixteen moles of amino acid, protein or hydrolyzed protein per mole of metal, said metal being stabilized by a buffering system comprising a member or members selected from the group consisting of amino acid-hydrochloric acid mixtures, or amino acid-sodium hydroxide mixtures and mixtures of alkali or alkaline earth metal salts of acid phthalates, neutralized phthalates, acid phosphates and acid carbonates with hydrochloric acid, sodium hydroxide and alkali or alkaline earth metal salts of acid phosphates, phosphates and carbonates, wherein the buffering system maintains the metal proteinate at a relatively constant pH between about 7 and 11.
A method of aiding in the assimilation of essential metals into warm blooded animals which comprises administering to said warm blooded animals an effective amount of an aqueous solution of a stabilized metal proteinate comprising a metal coordination complex between a metal ion selected from the group consisting of iron, copper, zinc, manganese, cobalt, chromium, calcium, magnesium and vanadium, and an amino acid selected from group consisting of glycine, alanine, valine, leucine, isoleucine, phenylalanine, tyrosine, tryptophan, serine, threonine, aspartic acid, glutamic acid, lysine, arginine, histidine, cystine, cysteine, methionine, proline, hydroxyproline and mixtures thereof;
- the proteins made up from said amino acids and hydrolysis products of such proteins in a molar ratio of between two and sixteen moles of amino acid, protein or hydrolyzed protein per mole of metal, said metal being stabilized by a buffering system comprising a member or members selected from the group consisting of amino acid-hydrochloric acid mixtures, or amino acid-sodium hydroxide mixtures and mixtures of alkali or alkaline earth metal salts of acid phthalates, neutralized phthalates, acid phosphates and acid carbonates with hydrochloric acid, sodium hydroxide and alkali or alkaline earth metal salts of acid phosphates, phosphates and carbonates, wherein the buffered system maintains the metal proteinate at a relatively constant pH between 7 and 11.
