Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
52 words
In an aqueous nutrient infusion solution comprising an effective amount of essential L-amino acids, including L-tryptophan, the improvement therein being that (a) substantially all of said L-tryptophan is in the form of L-tryptophyl-L-alanine or L-tryptophyl-L-leucine or mixtures thereof and (b) wherein said solution does not have a stabilizer as an ingredient thereof.
Claim 2
Dependent Claim
52 words

Claim 3
Dependent Claim
67 words
The nutrient infusion solution according to claim 1 comprising (a) at least one dipeptide selected from the group consisting of L-tryptophyl-L-alanine and L-tryptophyl-L-leucine; and (b) at least one amino acid selected from the group consisting of L-isoleucine, L-leucine, L-lysine, L-methionine, L-phenylalanine, L-threonine, L-valine, L-alanine, L-arginine, L-aspartic acid, L-cysteine, L-glutamic acid, glycine, L-histidine, L-ornithine, L-proline, L-serine and L-tyrosine; and failing to have a stabilizer as an ingredient thereof.
