What relationship exist between amino acid and protein?

Explanation:

When connected together by series of peptide bonds, amino acids form a polypeptide, another word for protein. The polypeptide will then fold into a specific conformation depending on other interactions (dashed lines) between its amino acid side chains.

It depends on which pet you like more or prefer!!

Explanation:

A puppy is a lot of work, so I think I would choose the 2 ragdoll kittens since they can grow up together :}
