Effects on proteins
hydrophobic regions of the proteins, par-
ticularly near tryptophan residues (Sikorski
et al.,
1987). Another possibility could be
the incorporation of ARs to a biological
membrane, which can decrease the lipid
ARs are able to inhibit the activity of sev-
eral enzymes. This effect may be mediated
by direct binding of these compounds to the
