A bit like psychopathic
but not at all like amphitheater
. This word seems to only be used for describing chemicals - fatty acid
s or alpha helices
. In these terms, it means that the structure posseses both hydrophobic
groups or atoms. This means that, in bulk, it will tend to assemble
into higher structures.
A relevant example are the toxins produced by some bees, which are simple helices (Mellitin, for example - although other insects, frogs and humans cells produce cytotoxic helices). These assemble into pores when they encounter a membrane, allowing free passage of ions - which affects the working of the cell and can pronote cell death.
