Abstract: | Among the brain areas studied only pars distalis and pars intermedia are found to contain β-lipotropin activating enzyme indicating that these may be the exclusive organs for a physiologically significant conversion of β-lipotropin into β-endorphin. β-Endorphin inactivating enzyme is found to be rather uniformly distributed in all the pituitary and brain regions, α- and γ-endorphins are presumably formed by the action of this enzyme on β-endorphin. |
