Effect of a Lindlar catalyst on an alkene?

rblake92

I know a Lindlar catalyst will cause syn addition of hydrogens to an alkyne and then stop at an alkene, but what about a molecule that has both an alkyne and an alkene in it to start. Is the alkene taken to an alkane or is it simply not affected? Thanks for your answers.

Lindlar's catalyst is poisoned so that it do not reduce the double bonds furthur into single bond.
