Our philosophy was too incorporate the parts of biochemistry likely to be seen on the C/P section in the organic chemistry book. You will encounter text-based review and practice passages on structure and reactivity in the carbonyl chapter, lipid chapter, carbohydrate chapter, and amine and amino acids chapter. You will also encounter a couple lab experiments on sequencing in that book. You will encounter isoelectric points in both our general chemistry and biology books. The parts of biochemistry that have to do with pathways and enzyme behavior (such as Lineweaver-Burke plots and enzyme kinetics) appear in chapters 7 and 8 of our biology book. We aimed to keep the B/B related biochemistry in our biology books. You will even encounter some biochemistry in the physics books with passages on electrophoresis.
Our basic philosophy is to make sure to present the fundamentals in the appropriate chapter readings, but that the passages make you apply aspects of biology, general chemistry, organic chemistry, and physics to biochemistry. This is why biochemistry questions appear in all four of our science books.
