The fibrous protein that is responsible for the strength and water resistance of the skin surface is
(a) Collagen
(b) Eleidin
(c) Keratin
(d) Elastin
(e) Keratohyalin
검증된 단계별 안내1
Understand the role of each protein listed in the options in relation to skin structure and function.
Recall that collagen is a fibrous protein primarily responsible for the strength and structural support of connective tissues, but it is located deeper in the dermis rather than the skin surface.
Recognize that elastin provides elasticity to tissues, allowing them to stretch and recoil, but it is not primarily responsible for water resistance.
Identify keratin as a fibrous protein found in the outermost layer of the skin (the epidermis), which provides both mechanical strength and water resistance to the skin surface.
Conclude that keratin is the correct protein responsible for the strength and water resistance of the skin surface.

Fibrous Proteins in the Skin
Fibrous proteins are structural proteins that provide strength, support, and protection to tissues. In the skin, these proteins contribute to its mechanical properties and barrier functions, making them essential for maintaining skin integrity and resilience.

Keratin and Its Role in Skin
Keratin is a tough, fibrous protein found in the outer layer of the skin, hair, and nails. It provides strength and water resistance to the skin surface by forming a protective barrier that prevents water loss and protects against environmental damage.

Other Skin Proteins: Collagen, Elastin, Eleidin, and Keratohyalin
Collagen provides tensile strength deeper in the skin, elastin allows skin elasticity, eleidin is a clear protein in the stratum lucidum aiding transparency, and keratohyalin granules help in keratinization. Each has distinct roles but keratin is key for surface strength and water resistance.
