When learning about amino acids, the primary things that were pointed out were that they had an amino group and a carboxyl group, and side chain that varies from one to the other.
The amino group of one can attach to the carboxyl group of another, making a peptide bond and water.
Both groups are clearly important, but what is it about the amino group that that's what goes in the name "amino acid"? Is the amino group in some way more important? Is it just something about the way/order in which they were discovered/identified that the name just came about?
Why amino acid? Not carboxyl acid, or some mix of the two, or something else?
