### pi bond breaking

I am aware that a pi bond, unlike a sigma bond, cannot rotate and if a pi bond does try to rotate the bond breaks. What are the biological implications of a pi bond breaking in our bodies?

### Re: pi bond breaking

I remember either hearing or reading that the breaking of pi bonds is important in vision, but that’s the only specific example I can recall. The presence of pi bonds is important in determine the shape of a molecule because it is stiffer than a sigma bond, which is likely important for proteins, as they must maintain a certain shape in order to properly function.
