Do I need to memorize all 20 amino acids for the DAT?

 

[cyrano]

No. I don't think so.

 

[NyCzPeter]

Absolutely positively not

I agree with everyone else, No def not!!

You definitely don't have to memorize the structures of the amino acids. The only thing I would consider reviewing is isoelectric points, etc. If they give you pKa's of certain groups on an amino acid you should be able to figure out its net charge at a particular pH, or predict a pH at which the total net charge of the molecule is zero.

I think I remember having a similar problem on my DAT. Basically as the pH crosses the pKa of a certain group, that group will become deprotonated. This is just a simple way of using a biochem structure to facilitate a general chem/o-chem principle.

No you dont need to memorize all that, now you can focus on other things 🙂

save that for biochem and/or dschool
