Which molecule is described as being composed of short chains of amino acids?

Explanation:
In this topic, think about how long a chain of amino acids is. A peptide is the basic term for a short chain of amino acids joined by peptide bonds. When the chain gets longer, it’s called a polypeptide, and many polypeptides together form a protein. An amino acid is just a single building block, not a chain. An oligopeptide does describe a short chain as well, but peptide is the more general and commonly used term for short amino acid sequences. So, the description “composed of short chains of amino acids” best fits a peptide.
