Verified step by step guidance

Understand the basic structure of amino acids: Amino acids are organic molecules that consist of an amino group (-NH₂), a carboxyl group (-COOH), a hydrogen atom, and a unique side chain (R group) attached to a central carbon atom.

Learn how amino acids link together: Amino acids are joined by peptide bonds, which are formed through a dehydration reaction between the carboxyl group of one amino acid and the amino group of another.

Recognize the role of proteins: Proteins are macromolecules composed of one or more chains of amino acids. These chains fold into specific three-dimensional structures that determine their biological function.

Understand the relationship between amino acids and proteins: Amino acids serve as the building blocks of proteins. Proteins are synthesized by linking amino acids in a specific sequence dictated by genetic information.

Clarify the incorrect options: Proteins are not made of a single amino acid, nor are they unrelated to amino acids. Proteins are synthesized from amino acids, not broken down into them during synthesis.
