Text to Cower Page figure: Animal venoms represent a vast reservoir of bioactive molecules potentially applicable in human medicine. Professor Gubenšek dedicated most of his scientific career to the study of the nose-horned viper (Vipera a. ammodytes) venom components. The structure of one of these, the neurotoxic ammodytoxin, is shown. The group he led also participated in sea anemone (Actinia equina), black widow spider (Latrodectus tridecimguttatus) and marine snail (Conus consors) venom research.
