To be honest I'm not really sure what advice to give you. You're probably in a spot where your knowledge/perspective is advanced enough to make you impatient around the fundamentals, and at the same time I'm not sure that you have the background required to take full advantage of more advanced materials. You don't seem to be where most 16 year olds are, is what I'm trying to say.

This is especially tricky in the field of bio / biochem, which feels like it requires memorizing a million facts before one gets to do any real thinking and reasoning. This unfortunately tends to filter out a lot of more mathematically-minded people who are stimulated by puzzles, which I think is a shame.

For what it's worth, I really enjoyed this textbook. I'm not sure you will find in it what you're hoping to find, but I hope it sparks even more curiosity; it's fairly advanced, probably more targeted at late-BSc or MSc/PhD students: https://www.amazon.com/First-Course-Systems-Biology/dp/08153...
