Verified step by step guidance

Understand the question: A sulfhydryl group is a functional group in biochemistry that consists of a sulfur atom bonded to a hydrogen atom (-SH). It is commonly found in thiol-containing molecules.

Review the options provided: -SH, -COOH, -NH₂, and -OH. Each represents a different functional group in biochemistry.

Identify the correct functional group: The sulfhydryl group is specifically represented by -SH, as it contains sulfur (S) bonded to hydrogen (H).

Compare the other options: -COOH represents a carboxyl group, -NH₂ represents an amino group, and -OH represents a hydroxyl group. None of these contain sulfur, so they cannot represent a sulfhydryl group.

Conclude that the correct answer is -SH, as it matches the definition and structure of a sulfhydryl group.
