I am not sure how adcoms would see it but I don't think it would impact your ability to get an interview. My university actually splits biochem into a lecture portion for 3 credit hours and a separate experimental biochem course for 3 credit hours. If my minor wasn't biochem I could easily take the lecture portion as a free elective and forgo the lab portion. I do think that labs are incredibly important though as it allows you to take what you learned from lecture and apply it to the real world.
