amino acids Flashcards
what amino acids are ketogenic
lysine and leucine
what amino acids are both ketogenic and glucogenic
tryptophan
phenylalanine
tyrosine
isoleucine
(the three aromatic and then isoleucine)
what amino acids are acidic
aspartate and glutamate
side chain is going to be around 4
what amino acids are basic
lysine
arginine
histidine
what amino acids are polar
(these all contain an OH)
serine
threonine
cysteine
(these all contain an amide)
glutamine
asparagine
histidine (think about the extra nitrogen in the ring)
what is the pKa of lysine’s side chain
about 9-10
what is the pKa of arginines side chain
about 12
what is the pKa of histidine side chain
about 6
what is the pKa of the COOH group
about 2-3
what is the pKa of the NH3 group
about 9-10
N
asparagine
R
