Wool fiber is considered amphoteric because it contains both acidic and basic functional groups in its protein structure, specifically keratin. This duality allows wool to interact with both acidic and alkaline substances, enabling it to absorb moisture and regulate pH levels. Consequently, wool can effectively balance and respond to varying environmental conditions, making it a versatile material for clothing and insulation.
