A micelle-forming new dipeptide, Boc-Lys(Z)-Tyr-NHNH2, has been synthesised in our laboratory and characterised.The critical micelle concentration (c.m.c.) of this peptide in aqueous solution has been determined at different temperatures using UV-VIS, fluorescence and FTIR spectroscopies, and conductometric techniques.The c.m.c.s obtained by these methods are in good agreement with each other.The effects of sodium dodecyl sulfate (SDS) and cetyltrimethylammonium bromide (CTAB) on the micelle formation of the dipeptide have also been studied.The aggregation numbers of the peptide and peptide-surfactant complexes have been determined by fluorescence techniques using the Mg salt of 8-anilino-1-naphthalenesulfonic acid (ANS) and N-cetylpyridinium chloride (CPC) as probe and quencher, respectively.The enhancement of water IR intensity (at 3410 cm-1) in the peptide at concentrations above the c.m.c. during FTIR measurements suggest the presence of intermolecular H-bonding of the peptide micelles.
Synthesis of PHI (Peptide Histidine Isoleucine) and Related Peptides and Immunochemical Confirmation of Amino Acid Residue in Position 24 of PHI with use of the Synthetic Peptides

An immunochemical approach, using synthetic peptides, was employed to establish the nature of residue 24 in the amino acid sequence of PHI (peptide histidine isoleucine).PHI(20-27) and 24>-PHI(20-27) were synthesized by conventional solutio
