The atom names on the left correspond to the convention of Greek alphabet,
with alpha being "next to" the highest priority functional group, the C=O,
whose carbon is simply labeled C and whose oxygen is named O.

Beta, "next to that"...etc.

CA = the C alpha carbon
CB= the C beta carbon
CG= the C gamma carbon
CD = the C delta carbon
OE= the O in the epsilon position


Do not confuse those with the atom types...

BTW, you have GLN up there, not GLU...

Good luck...
