Alpha Keratin
Research
20 / 1000+ resultsresearch Exploring Biological Tissue from Atomic to Macroscopic Scale Using Synchrotron Radiation: Example of Hair
Hair has unevenly distributed proteins and lipids, with lipids mainly in the cuticle and proteins in the cortex and medulla.
research Regulation of Hard Alpha-Keratin Mechanics via Control of Intermediate Filament Hydration: Matrix Squeeze Revisited
Hard α-keratins stay stiff in water because the surrounding matrix keeps them dehydrated and strong.
research In Vitro Evaluation of Changes in Hair Fibers Subjected to Oxidation-Reductive Straighteners Associated with Dyeing
Straightening and dyeing damage hair structure.
research Hard Alpha-Keratin Degradation Inside a Tissue Under High Flux X-Ray Synchrotron Micro-Beam: A Multi-Scale Time-Resolved Study
High flux X-ray beams quickly damage the structure of human hair.
research Morphology and Properties of Hair
Hair is made of strong keratin fibers that protect against the environment.
research The Human Hair: From Anatomy to Physiology
The document concludes that hair is complex, with a detailed growth cycle, structure, and clinical importance, affecting various scientific and medical fields.
research Increased Rate of Hair Keratin Gene Loss in the Cetacean Lineage
Cetaceans lost hair genes to adapt to water.
research Organization of Microfibrils in Keratin Fibers Studied by X-Ray Scattering
The study improved understanding of keratin fiber structure by showing consistent microfibril diameter but varying distances and electron density profiles.
research Female Cadaver in the Han Tomb No. 1: X-Ray Diffraction Studies on Two Kinds of Fibrous Protein
The protein structures in the hair and tendon were preserved, but their molecular arrangements changed.
research Keratinization of Sheath and Calamus Cells in Developing and Regenerating Feathers
Feathers become harder as they develop due to a change in keratin type.
research Molecular Changes in Skin Predict Predisposition to Breast Cancer
Skin changes can indicate a risk for breast cancer.
research Generalized Trichorrhexis Nodosa: A Case Study
The hair disorder was caused by abnormal protein formation, making hair easily damaged.
research The Use of Electron Spin Resonance Techniques to Determine Gamma Ray Exposure of Alpha-Keratin in Human Hair
Whole hair strands can reliably measure gamma ray exposure using ESR techniques, but samples should be analyzed quickly or stored in liquid nitrogen.
research Isolation of Intermediate Filament Assemblies from Human Hair Follicles
Researchers isolated and identified structural components of human hair follicles, providing a model for studying hair formation.
research Ultrastructural Localization of Hair Keratin Homologs in the Claw of the Lizard Anolis Carolinensis
Lizard claws have hair-like keratins similar to those in mammals.
research Attenuated Total Reflection Fourier Transform Infrared Spectroscopy Analysis of Human Hair Fiber Structure
Human hair has different protein structures in its cuticle and cortex.
research A Rapid Extraction Procedure of Human Hair Proteins and Identification of Phosphorylated Species
A new method quickly extracts and identifies proteins from hair and other keratin sources.
research Proteomic Tools for the Investigation of Human Hair Structural Proteins and Evidence of Weakness Sites on Hair Keratin Coil Segments
Hair proteins have weak spots in their α-helical segments.
research The Process of Cornification Evolved From the Initial Keratinization in the Epidermis and Epidermal Derivatives of Vertebrates: A New Synthesis and the Case of Sauropsids
Cornification evolved from keratinization in vertebrates, with differences between mammals and sauropsids.
