These are my personal study notes from the EdX online course, MCB63X: Intro to Biochemistry from Harvard-X 
as taught by Dr. Alain Viel and Dr. Rachelle Gaudet in the summer of 2015. They are organized by lecture. 
Please note that these are not the official class lecture notes and are not meant to replace the course in any way. 
Other disclaimers apply.

Suggestion: for each section, open the corresponding lecture slide (they’re numbered the same) and follow along.
