Visao Geral da Pesquisa Glutathione (GSH) is a ubiquitous endogenous tripeptide que serves como o(a) principal intracellular antioxidante and redox buffer in mammalian biology. Composed of L-glutamate, L-cysteine, and glycine, it foi isolado(a) pela primeira vez and named by Frederick Gowland Hopkins in 1921, though its correct tripeptide structure nao foi estabeleceu until 1935 by Harington and Mead. Present at millimolar concentrations (0.5–10 mM) in virtually every cell, GSH participate

How does Glutathione work? What is its mechanism of action?

Mecanismo de Acao Glutathione (GSH) nao function atraves de um(a) single classical receptor-ligand interaction. Instead, it acts como um(a) pervasive biochemical modulator of cellular redox state, enzymatic cofactor, and signaling regulator via post-traducaoal protein modification.[3] Primary Biochemical Targets & Binding Characteristics Target / MechanismDetailEvidence S-GlutathionylationReversible post-traducaoal modification; GSH forms mixed disulfide bonds with reactive cysteine residues

What are the research applications of Glutathione?

Aplicacoes de Pesquisa Glutathione is investigated across a broad spectrum of research domains, with evidence spanning preclinical modelo animals to randomizado controlled ensaios clinicos: 1. Neurodegenerative Diseases (Parkinson's, Alzheimer's) GSH depletion no(a) substantia nigra is one do(a) earliest biochemical changes in Parkinson's disease, preceding mitochondrial Complex I dysfunction and dopaminergic neuron loss. In a Phase IIb RCT, UPDRS Total endpoints were assessed, and a magnetic re

How should Glutathione be stored?

Liofilizado: -20°C ou 2–8°C (estável longo prazo como pó seco); proteja da luz, ar e umidade.

How to Store Glutathione — Storage & Handling Guide

Pó Liofilizado

Store at -20°C for optimal estabilidade a longo prazo, or at 2–8°C for routine storage. The dry powder form is relatively estavel but deve ser kept in tightly sealed, opaque containers para proteger from light and moisture. Glutathione is highly susceptible to oxidation na presenca de air and elevated humidity (water activity >0.3).

Solubilidade

Solúvel em água estéril ou PBS. Aqueous GSH solutions oxidize rapidly to GSSG quando exposto(a) a air.

Quality & Handling

Supplied como um(a) white crystalline powder. Os certificados publicados informam a pureza por HPLC e as endotoxinas quando testadas. Incompatible with strong oxidizing agents. CAS: 70-18-8, PubChem CID: 124886.
