Thanks for the reply! Sorry for the confusion : I should have stated biochemistry. I went through this course (below)which was really interesting. However the course focused more on synthetic Chemistry and only briefly touched upon how active compounds are found and extracted from natural compounds. I also read about biotechnology and went through some lecturers on YouTube and MIT intro to bio course. The impression I get is biotech (recombinant DNA) is cheaper than drug discovery? Drug discovery seems to have a lot more factors you need to be concerned about (clearance rate, bioavaibilty, binding to too many proteins )that make seem more expensive https://www.edx.org/course/medicinal-chemistry-the-molecular-basis-of-drug-discovery-0 https://www.edx.org/course/medicinal-chemistry-the-molecular... Would you mind recommending couple of books so I could gain some more knowledge on the subject. I just purchase “organic chemistry or drug design and drug action”
