KK: /sʌlˈfaɪdrɪl/
A chemical group consisting of a sulfur atom bonded to a hydrogen atom, often found in organic compounds and proteins.
Cysteine contains a sulfhydryl group that can form disulfide bonds, which are important for protein structure.
Sulfhydryl → It is formed from "sulfur" (from Latin *sulfur*, meaning the chemical element sulfur) and "hydryl" (from Greek *hydro-* meaning water and *-yl* indicating a functional group). The word refers to a functional group containing sulfur and hydrogen, often represented as -SH.
Think of 'sulfur' as the key element and 'hydryl' indicating a group related to water, which helps you remember that sulfhydryl refers to a group containing sulfur and hydrogen.
