Research
300-330 / 1000+ resultsresearch Metabolomic analysis of amino acids and lipids in human hair altered by dyeing, perming and bleaching
Chemical treatments like dyeing, perming, and bleaching damage hair by altering amino acids and lipids.
research The susceptibility of disulfide bonds to modification in keratin fibers undergoing tensile stress
Disulfide bonds in keratin fibers break more easily under stress, especially when wet, affecting fiber strength.
research Disturbed Keratinocyte Differentiation in Transgenic Mice and Organotypic Keratinocyte Cultures as a Result of Spermidine/Spermine N1-Acetyltransferase Overexpression
Overexpression of SSAT causes hair loss and skin issues, but reducing putrescine can help.
research Structural Stability of Wild Type and Mutated α-Keratin Fragments: Molecular Dynamics and Free Energy Calculations
The Glu413Lys mutation in keratin affects hair stability, while Glu413Asp does not.
research Thiazole: A Versatile Standalone Moiety Contributing to the Development of Various Drugs and Biologically Active Agents
Thiazole, a sulfur and nitrogen chemical, is useful in creating potential drugs for conditions like seizures, cancer, bacterial infections, tuberculosis, inflammation, malaria, viruses, Alzheimer's, diabetes, and A1-receptor issues.
research Comment on 'A prospective real world study evaluating serum levels of arginine and cysteine in females with chronic telogen effluvium: do we really need blanket prescription with amino acid supplementation?'
Amino acid supplements may not be necessary for all women with chronic hair loss.
research Demethylation of methionine and keratin damage in human hair
Copper and iron cause keratin damage in hair by converting methionine to homocysteine.
research Application of XANES profiles to X-ray spectromicroscopy for biomedical specimens: Part II. Mapping oxidation state of cysteine in human hair
Perming and bleaching damage hair differently, with bleached hair having more cysteic acid in the cuticle.
research Structural changes in hair follicles and sebaceous glands of hairless mice following exposure to sulfur mustard
Sulfur mustard damages hair follicles and sebaceous glands in mice.
research Acrodermatitis dysmetabolica in an infant with maple syrup urine disease
Increasing isoleucine intake improved skin and health issues in an infant with maple syrup urine disease.
research Steroid sulfatase inhibitors
Steroid sulfatase inhibitors could help treat hormone-related disorders and cancers.
research Hair Keratin Associated Proteins: Characterization of a Second High Sulfur KAP Gene Domain on Human Chromosome 2111In fond memory of Dr Peter Steinert.
A second domain of high sulfur KAP genes on chromosome 21q23 is crucial for hair structure.
research Mutations in Homocysteine Metabolism Genes Increase Keratin N-Homocysteinylation and Damage in Mice
Genetic mutations that disrupt homocysteine breakdown lead to increased damage in mouse hair keratin.
research The Proteins of Normal and Aberrant Hair Keratins
Hair is mostly made of three protein types: helical, high-sulfur, and high-tyrosine.
research Photoinduced formation of thiols in human hair
UV exposure damages hair, increasing thiols and altering protein structure.
research The influence of sulfur and hair growth on stable isotope diet estimates for grizzly bears
Sulfur slightly improved diet estimates for grizzly bears, but hair growth timing varied, affecting results.

Sulphur, phosphorus, and metals are distributed differently in animal skin follicles, with variations in detection speed and location.
research Ultrastructural Localization of S100A3, a Cysteine-rich, Calcium Binding Protein, in Human Scalp Hair Shafts Revealed by Rapid-freezing Immunocytochemistry
S100A3 protein is mainly found in specific parts of human hair cells.
research Acrodermatitis Enteropathica‐like Eruption in an Infant with Nonketotic Hyperglycinemia
A baby with a rare metabolic disorder developed a rash not cured by zinc alone, likely due to both zinc and amino acid deficiencies.
research Sulphation catalysed by the human cytosolic sulphotransferases - chemical defence or molecular terrorism?
Human enzymes can detoxify harmful substances but might also increase their cancer risk.
research Metabolic Engineering of Microorganisms to Produce L-Aspartate and Its Derivatives
Scientists can use engineered microbes to make L-aspartate and related chemicals, but there's still room to improve their efficiency.
