Which amino acid contains sulfur in its side chain?
Step 1: Understand what an amino acid is. Amino acids are the building blocks of proteins.
Step 2: Learn that amino acids have a central carbon atom, an amino group, a carboxyl group, a hydrogen atom, and a side chain (R group).
Step 3: Recognize that the side chain is what makes each amino acid unique.
Step 4: Identify that some amino acids contain special elements in their side chains, such as sulfur.
Step 5: Find out which amino acid has sulfur in its side chain. The amino acid cysteine has a side chain that contains a thiol group (-SH), which includes sulfur.
