Abstract: A test method using ultra filtration to profile metal proteinates to evaluate their potential efficacy.

Abstract: A method of assaying metal proteinate samples to determine compliance with European Union standard definitions for such products.

Abstract: The method and composition involves preparing a high yield of a metal amino acid complex visible as a source of highly bioavailable transition metal ions, highly bioavailable essential amino acid for a livestock animal is disclosed. The method involves preparing the metal amino acid complex from a protein starting material resulting product in high yield. The protein starting material is hydrolyzed to provide an amino acid hydrolyzate and thereafter a metal oxide corresponding to the desired metal for the metal amino complex is added to the amino acid hydrolyzate to react to form a high yield metal amino acid complex which is thereafter used to form a dose for supplementation of diet to assure adequate trace minerals and adequate essential amino acids in the diet of a livestock animal.

Abstract: Novel salts are prepared wherein the cation of the salt is a divalent or trivalent cation which is an essential trace element comprising a 1:1 ratio of a complex ion formed between a trace mineral and methionine and any suitable anion, either inorganic or organic. The novel salts have the generic formula: ##STR1## Wherein R.sub.1 is methyl or ethyl, R.sub.2 is hydrogen, methyl or ethyl, R.sub.3 is hydrogen or methyl, M is a covalent or trivalent trace mineral cation, X is an anion and w is an integer to balance the anionic charge of X. These novel compounds are useful nutritional supplements, both for animals and humans, in that they provide a readily available source of a highly water soluble methionine which is an essential amino acid.

Abstract: Novel complex salts wherein the cation of the salt is a complex between iron and methionine. These salts are useful for nutritional supplementation to provide iron and methionine, both in a form which effectively increases the bioavailability of these compounds to animals.

Abstract: Novel pharmaceutical compositions containing 1:1 zinc methionine complex salts having the formula:[CH.sub.3 SCH.sub.2 CH.sub.2 CH(NH.sub.2)COO.sup.. Zn.sup.+.sup.+].sub.w Xwherein X is an anion and w is an integer equal to the anionic charge of X. These compounds when administered in dosage form have been found to have therapeutic effect in the treatment of certain epidermal disorders such as acne.

Abstract: 1:1 Zinc methionine complex salts having the formula[CH.sub.3 SCH.sub.2 CH.sub.2 CH(NH.sub.2)COO.Zn.sup.+.sup.+].sub.w Xwherein X is an anion and w is an integer equal to the anionic charge of X. These are useful nutritional supplements, both for animals and humans, in that they provide a readily-available source of the zinc ions necessary for dietary balance and provide methionine, an essential amino acid, in a form which provides for body conversion of more of the methionine to protein than does the simple feeding of the compound methionine.

Abstract: Novel salts are prepared wherein the cation of the salt comprises a 1:1 ratio complex of a complex ion formed between manganese and an alpha amino acid, and any suitable anion, either inorganic or organic but preferably a monovalent inorganic anion. The novel salts have the formula: ##EQU1## wherein X is an anion, W is an integer equal to the anionic charge of X, and R is an alpha position moiety of an essential amino acid. The preferred amino acids are methionine and glycine. These compounds are useful nutritional supplements, both for animals and humans in that they provide a readily available source of manganese ions necessary for dietary balance. In addition, these complexed salts also provide a readily available source for certain amino acids needed in a balanced diet, such as methionine.
