1. HYDROPHOBIC: When my Volkswagen has an empty tank, I have to go buy some
hydrophobic fuel at the gas station so I can
F phe
I ile
L leu
M met
Y tyr
V val
W trp (double-U, double ring)
2. POLAR: When the British gave Hong Kong to China, a lot of political polarization was
produced by the Communists, or:
H his
K lys
E glu (5th letter, 5 carbons)
R arg "ARginine"
D asp (4th letter, 4 carbons)
3. ALIPHATIC: The hydrophobic and polar amino acids get all the attention, but there is
something to be said for the "normal" amino acids, which simply have their first letter as the
one letter code. They are "pretty good cats":
P pro
G gly
C cys
A ala
T thr
S ser
4. AMIDES: The two amides are Glutamine (say "Q"-tamine) and Asparagine, which
differs from Aspartate by its amide nitrogen (AsN = "N"). [Not used very often are the
letters B (either D or N) and Z (either E or Q)].
Q Gln "Q-tamine"
N Asn
5. LEFTOVERS. The alphabet has 26 letters. Twenty are used for single amino acids,
two are used for "either or" amino acids, and there are four left over. It is useful to
remember which letters are not used in this scheme. The leftovers have no use, so they are
like toys, or in French:
[In fact "O" is sometimes used for Ornithine, but that's not used in protein synthesis.]
