Peptide and Protein Structures Quiz

• Peptides are short chains of amino acids, while proteins are longer polymers made up of amino acids
• Amino acids in a peptide are linked together via peptide bonds
• Each amino acid residue in a peptide has an amino-terminal (N-terminal) with a free amino group and a carboxyl-terminal (C-terminal) with a free carboxyl group
• Peptides can range from 2 to 40 amino acids and are named or numbered starting from the amino terminus
• Amino acids can be joined by multiple peptide bonds to form oligopeptides (tripeptides, tetrapeptides, etc.) or a long chain of many amino acids called a polypeptide. Proteins contain one or more polypeptides.
• Peptide bond formation involves the removal of a water molecule and the formation of an amide linkage between the amino group of one amino acid and the carboxyl group of another.
• Amino acids can be represented with their three-letter or single-letter abbreviations, such as Trp (tryptophan), Ala (alanine), and Ser (serine)
• Peptides and proteins have specific structures, including primary, secondary, and tertiary structures, which determine their function in the body.
• Peptides and proteins play essential roles in various biological processes, such as enzyme activity, structural support, and signaling.
