I was wondering about element distribution in the universe, specifically if any inconsistency in the relative distribution of elements would have any significant effects on the chemistry of a galaxy. How likely is it that there could be significant differences in element quantities from one galaxy to another, so that certain common, or 'important' chemical compounds or reactions might not be possible/probable.

For example could a galaxy not have the proper relative quantities of elements used in organic chemistry to allow the sort of organic chemistry we see occurring in many places in our own local space (comets and cosmic dust)?
