Biological fluids as chiral anisometric media.
Molecules of dissolved substance in many homochiral solutions are arranged in linear associations forming chiral strings (with length to diameter proportion of 10(1)-10(5)), which leads to solidification of the solution into anisometric gel. This paper describes the formation of the string system in aqueous solution of amino acid phenylalanine, formation of individual strings, weaving of thin strings into thick ones, successive alteration of the solution chirality sign with transition to new levels of the association organization. It seems that biological media are anisometric fluids containing chiral molecular associations and strings, or anisometric gels.
