Page/Page column 6, (2008/12/06)
The present invention provides a composition for oral administration, which comprises at least one kind of dipeptide represented by the formula: ????????X-Y (wherein X represents alanyl, glycyl, arginyl, seryl, α-aspartyl or α-glutamyl, and Y represents valine, leucine or isoleucine), with an object of providing a composition for oral administration which is excellent in nutrition, pharmacological effect and gustation and comprises at least one kind selected from valine, leucine and isoleucine, or providing a composition for oral administration which is excellent in processing characteristics such as solubility and tableting property and comprises at least one kind selected from valine, leucine and isoleucine.
ASYMMETRIC TRANSFORMATION OF AMINO ACIDS IN N-SALICYLIDENE AMINO ACYL-L-ISOLEUCINATOCOPPER(II)

A new asymmetric transformation of amino acids was described.Thus, when N-salicylidene-D-alanyl-, D-phenylalanyl-, or D-phenyl-glycyl-L-isoleucinatocopper(II) was incubated at pH 8.5 and 80 deg C, the resulting mixture at equilibrium contained a complex of L-L-dipeptide in the contents of 63-76percent.The epimerization of dipeptides is based on the enhanced activity of N-terminal amino acids through complex formation.
