Peptide bond#("a covalent bond")#.

Explanation:

Each amino acid molecule consists of an amino group#(NH_2)# and carboxyl group#(COOH)# and variant side chain#(R)# attached to an alpha carbon#(C)#. When the two amino acid come along each other, the positively charged #alpha#-amino group of one amino acid reacts with the negatively charged carboxyl group of another amino acid releasing water molecule#(H_2O)#. This reaction is called condensation reaction and the linkage formed b/w two amino acids is called peptide linkage or peptide bond.

That's how amino acids join by means of peptides bond to form long polypeptide chains if proteins.

Hope it helps...
