Cucurbitacin (C 30 H 42 O 7 ) is a molecule in the MineChem universe which functions primarily as an intermediate.

Uses
Aside from synthesizing the above, Cucurbitacin is a good source of hydrogen, carbon, and to a lesser extent oxygen. Because it comes from pumpkins and melons, it is one method of having an infinite source of hydrogen, oxygen, and carbon (all of which are frequently used elements).
