I won't say don't memorize anything, but what I would recommend is to not focus on blatantly memorizing everything. The test is, and always will be, a concept understanding and knowledge incorporation test. So while memorizing all the amino acids might be helpful on the off-chance they ask you to identify it structurally (they can, but the chances of this are highly unlikely), try to shift your thinking more towards which ones are more hydrophobic/philic or better acids/bases, for example.
My first MCAT attempt I thought that memorizing all the formulas would give me a sort of cushion where if I stumbled onto an unfamiliar topic, I could refer to a formula on it for help. Could not be more wrong. You will memorize 100+ formulas and will likely use a handful, if even, on the test. Understanding what they tell you about a concept is far more important (and if you understand the concept, you're more likely to remember them anyway!). The same goes for the various anabolic and catabolic processes. Try to shift your thinking away from this. Memorizing nitty-gritty details like enzymes should be one of the last things you do in your studying.
