difference in the crystal structure and growth kinetics of
microtubes formed from l- and d-enantiomers of diphenylalanine
dipeptide is investigated both experimentally and theoretically by
computer simulation. The microtubes of l- and d-enantiomers
grown simultaneously and under identical experimental conditions possess
different crystallographic space groups, have essential difference
in sizes, and demonstrate different growth kinetics. Computer simulation
by molecular mechanics methods revealed a fundamental difference in
the interaction between structural units of microtubes of different
chiralities. A model describing chirality-dependent growth of microtubes
is proposed.
