Abstract

Five bifunctional α-amino acid-ε-carboxy bolaamphiphiles [(2-R, S, or RS)-(HOOC)-(CH2) m- CONH-(CH2) n-CH (COOH)(NH2) m= 20, 22, n= 3, 4 labeled (l),(d, l)-C22Orn (l),(d),(d, l)- C22Lys,(d, l)-C24Lys respectively] were synthesized. These molecules were deposited on different aqueous subphases, and studied by means of grazing incidence X-ray diffraction (GIXD). On deionized water, the bolaamphiphiles (d, l)-C22Lys yield a mixture of ...
