The 69 pages that link to Keratin, each with the reason it gives.

• CollagenCompared with: Keratin reinforces epithelial structures, while collagen supports connective tissues.

• CarapaceRelated: Keratin forms the scutes covering many turtle carapaces.

• FeatherNarrower topic: Feathers are built primarily from keratin, a durable protein.

• EpidermisRelated: Epidermal keratins provide mechanical strength and vary as cells mature.

• ChitinRelated: Keratin often partners with chitin in arthropod cuticles.

• WoolRelated: Wool fibers consist primarily of keratin, whose structure gives them strength and flexibility.

• TetrapodRelated: Keratinized coverings and structures evolved into diverse adaptations across tetrapod branches.

• ReptileRelated: Keratin forms the scales, scutes, claws, and other protective structures found across reptiles.

• Stratum corneumRelated: Keratin filaments strengthen corneocytes and help them resist mechanical stress.

• Cutaneous respirationRelated: Thick keratinized coverings impede diffusion and restrict reliance on cutaneous respiration.

• Disulfide bondBroader topic: Disulfide crosslinks help determine the mechanical properties of keratin-rich materials.

• Hair shaftRelated: Keratin makes the shaft durable and resistant to ordinary wear.

• CytoskeletonBroader topic: Keratin illustrates how intermediate filaments reinforce cells and tissues.

• DyeRelated: Protein fibers such as wool and silk offer different dye-binding sites from cellulose.

• BaleenRelated: Baleen plates are made of keratin, which forms their durable, flexible structure.

• Composite bowNarrower topic: Horn's keratin structure helps explain its role as a compressive bow layer.

• ClawRelated: Keratin forms the hard material of claws.

• CuticleCompared with: Keratin-based coverings are not built from the chitin-protein matrix of arthropod cuticle.

• HairNarrower topic: Hair’s strength and shape depend on this structural protein.

• KeratinocyteRelated: Keratin filaments reinforce keratinocytes as they mature and strengthen the epidermal barrier.

• CysteineBroader topic: Cysteine-rich keratins gain mechanical strength from extensive disulfide cross-links.

• Cloven hoofRelated: Keratin forms the durable outer material of each hoof half.

• Hair textureRelated: Hair’s keratin-rich composition gives strands their mechanical properties.

• HoofNarrower topic: Hoof walls and soles are built from this durable protein.

• ScuteNarrower topic: Scutes consist of keratin, the same structural material found in reptile scales.

• MoultingRelated: Keratin forms many coverings that animals renew through moulting.

• Snake scaleRelated: Keratin forms the hardened outer material of snake scales.

• Turtle shellRelated: Keratin forms the scutes covering many turtle shells.

• AntlerRelated: It forms the outer material of true horns, not the bone of antlers.

• FeltNarrower topic: Wool’s keratin fibers provide the structure that enables felting.

• FolliculitisRelated: Keratin buildup can obstruct follicular openings and create noninfectious bumps that resemble folliculitis.

• KeratinizationRelated: Its accumulation gives keratinized tissue much of its strength.

• PangolinRelated: Pangolin scales are made of keratin, like mammalian claws.

• Rhinoceros hornNarrower topic: Compacted keratin forms the horn’s main material.

• TerbinafineRelated: Dermatophytes colonize keratin-rich tissues, where terbinafine is commonly used.

• Batrachochytrium dendrobatidisRelated: The fungus grows in keratinized amphibian tissues, including the outer skin layers.

• ReptiliaRelated: Keratinized coverings help limit water loss and protect reptile bodies.

• Guard hairNarrower topic: Keratin gives guard hairs their durable, relatively stiff structure.

• Hair straighteningRelated: Hair’s keratin fibers are reshaped by heat and chemical straightening treatments.

• Intermediate filamentBroader topic: Keratin filaments form tough networks that protect epithelia from stretching and abrasion.

• BleachingRelated: Its protein structure makes animal fibers respond differently from cellulose during bleaching.

• DermatophyteRelated: Dermatophytes digest keratin to obtain nutrients from their characteristic tissues.

• DermatophytosisRelated: Dermatophytes use keratin as their principal nutrient source.

• Hair growthRelated: Hair-shaft cells become durable fibers through keratin production.

• HornsRelated: A keratin sheath covers the bony core and forms the horn’s exposed surface.

• Tinea corporisRelated: Dermatophytes feed on keratin in the stratum corneum.

• BillRelated: Keratin forms the bill’s outer sheath.

• Hair dyeRelated: Hair dyes act on fibers built largely from keratin.

• OnychomycosisNarrower topic: Its abundance in nails helps explain why dermatophytes can persist there.

• Tinea pedisRelated: Dermatophytes exploit keratin, explaining their restriction to these tissues.
