Biochemistry Free For All (BFFA) is a new biochemistry textbook in an Open Educational Resource (OER) format appropriate for all levels of biochemistry. Developed using the Foundational Concepts defined by the American Society for Biochemistry and Molecular Biology (ASBMB) and the associated learning goals as a guide, BFFA was designed with students in mind. The book contains interactive learning modules, a comprehensive glossary, a summary of important points of the book, links to free online video lectures by Kevin Ahern, and dozes of fun items that include verses and recordings of the Metabolic Melodies biochemistry songs.
