Proteins play a key role in many biological functions. Insulin is a protein hormone that regulates blood sugar levels. Insulin is composed of chains of amino acids, which are linked together through specic covalent bonds during its synthesis in the pancreas. Which of the following represents the type of bonds that connect the monomers in insulin?
- A Monomers in insulin are connected via a peptide bond between the carboxylic groups of two amino acids.
- B Monomers in insulin are connected via a peptide bond between the carboxylic group of one amino acid and the amino group of a neighboring amino acid.
- C Monomers in insulin are connected via a peptide bond between the amino group of two amino acids.
- D Monomers in insulin are connected via a peptide bond between the R group of one amino acid and the amino group of a neighboring amino acid.
