The ultimate scientific pickup line! While humans get all smiley when told they're attractive, proteins have a more dramatic reaction - they literally unfold under heat. That bottom panel is biochemistry's version of a dad joke. When proteins get "hot" (as in temperature, not Instagram-worthy), their carefully folded structure falls apart faster than my self-control around free conference food. This process, called denaturation, is why egg whites turn from clear goo to solid white when cooked. Next time someone calls you hot, just remember - at least you're not unraveling your tertiary structure!
