    Amino Acids (e.g. Tyrosine) and their charge

    I recently checked out a document from UCLA a which shows the pKa's of each amino acid. I know that each protein's environment can have a affect on pKa's, or so I was told, but that is besides the point. My question is in regards to figuring out charge, specifically for tyrosine. Assumptions...

    Last Minute Amino Acid Help

    Hello all, my MCAT is this Thursday and I'm feeling good. One thing still befuddles me a lil. So when we're looking at an AAs charge in solution, are we looking at the pka or pI? Take Asparatate for example, it's pI is roughly 2.7 and it's pka is 4, so if a solution had a pH of 3, would it be...

    "pKw = pKa + pKb" formula explanation

    Hi guys, This may be a silly question, but I'm confused about the formula pKw=pKa+pKb (and I guess by extension Kw=Ka*Kb). My confusion came from an Examkrackers question asking "What is the pKb for HSO3-?" when given the pKa of H2SO3 (1.81) and pKa of HSO3- (6.91). The answer for the pKb of...
