A dipeptide glycylalanine consists of:
Correct answer: B. Glycine and Alanine
- A. Glycine and Glycine
- B. Glycine and Alanine
- C. Alanine and Alanine
- D. Glycine and Valine
Explanation
A dipeptide glycylalanine consists of the amino acids glycine and alanine. The amino acids are linked together by a peptide bond, which is an amide bond formed between the amino group of glycine and the carboxyl group of alanine. The name of the dipeptide is derived from the names of the amino acids, with the suffix "-yl" being added to the name of the first amino acid and the prefix "-yl" being added to the name of the second amino acid. In this case, the dipeptide is named glycylalanine because the glycine is linked to the alanine.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
