Verified step by step guidance

Step 1: Begin by understanding the structure and function of amino acids. Amino acids are the building blocks of proteins and are linked together by peptide bonds to form chains.

Step 2: Learn the terminology associated with chains of amino acids. A chain of amino acids linked by peptide bonds is specifically referred to as a 'polypeptide.'

Step 3: Differentiate between the given options: Triglycerides are fats composed of glycerol and fatty acids, polysaccharides are carbohydrates made of sugar units, and nucleic acids are molecules like DNA and RNA composed of nucleotides.

Step 4: Recognize that the correct term for a chain of amino acids is 'polypeptide,' as it directly describes the peptide bonds connecting amino acids in a linear sequence.

Step 5: Conclude that the other options (triglyceride, polysaccharide, nucleic acid) are unrelated to chains of amino acids and serve different biological functions.
