(a) Convert the below amino acid (Fischer Projection) to a tetrahedral structure (using the 4-carbon backbone provided below). Draw the predominant ionization states that would exist at
pH1.5
for the amine and carboxylic acid functional groups
pK_(a)(\alpha -CO_(2)H)=2.09,pK_(a)(\alpha -NH_(3)^(+))=9.10
. (b) State whether this is a D or an
L
amino acid (small box). In one sentence explain why (big box)?
