Question

which acts like an acid. amino acids also contain a third functional group, often called the r group. in alanine, the r group is a methyl group (ch3). in serine, the r group is a methyl alcohol (-ch2oh). alanine serine what functional groups will be joined together if alanine and serine molecules combine to form a single molecule? a an amino group and a carboxyl group b two amino groups c an amino group and a methyl group

Explanation:

Amino - acids form peptide bonds through a condensation reaction where the amino group of one amino - acid reacts with the carboxyl group of another. When alanine and serine combine, it is the amino group and the carboxyl group that react to form a peptide bond.

Answer:

A. an amino group and a carboxyl group
