Explanation:
Charged amino acid side chains can form ionic bonds, and polar amino acids are capable of forming hydrogen bonds. Hydrophobic side chains interact with each other via weak van der Waals interactions. ... When connected together by a series of peptide bonds, amino acids form a polypeptide, another word for protein.
