Within a protein, several amino acids are linked together by peptide bonds, forming a long chain. Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid.

2. They have an outer covering of scales
3. They breathe with the aid of lungs
4. Although most reptiles lay eggs, some also give birth to live young (fertilise internally)!
I hope this helps! :)
