The peptide bonds shown above between amino acids connects a C from the carboxyl group of one AA and an N from the amino group of another.

Which atom in the peptide bond keeps the electrons around it for a greater share of the time, and how do you know?

options:

	carbon, because it has a "delta+" near it
	nitrogen, because it has the lower electronegativity
	carbon, because there are more of them
	nitrogen, because it isn't connected to the R-group
	carbon, because it holds onto its electrons tighter than N does
	nitrogen, because it has a "delta-" near it
