Question

Quizplus · Accepted Answer

Pb (lead) is a heavy metal that can react with thiol groups (R-SH), forming a bond between the sulfur atom and the lead ion. This is a common interaction in biochemistry and environmental chemistry, where heavy metals like lead can bind to and potentially inhibit the function of proteins containing thiol groups.
