Amino Acid Identification: Sulfur Containing

In biochemistry, the structure and function of biological molecules such as proteins, carbohydrates, lipids, and nucleic acids are fundamental to understanding cellular processes. One important aspect of biological molecules is the classification of their structural components. For instance, amino acids, the building blocks of proteins, possess certain functional groups that determine their properties and roles in biological systems.

Which of the following amino acids contains a sulfur atom in its side chain?
