Biological assimilation of metals

Claim 1

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.

Claim 9

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.

Claim 10

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.
