ABSTRACT:
Disclosed is a fine fibrous assembly having a molecular structure of a bola-form peptide lipid containing L- or D-valine residues which can be obtained by spontaneous crystallization precipitation when an aqueous solution of the peptide lipid compound of the general formula ##STR1## in which Me is a methyl group, the subscript m is 1, 2 or 3 and the subscript n is a positive integer in the range from 6 to 18, in the form of an alkali metal salt is kept standing over days under an atmosphere of a saturated vapor over a dilute aqueous solution of a vaporizable acid such as acetic acid.
