Frequently Asked Questions

: What exactly is glutathione peptide for sale at Apeptide?
A: Glutathione (GSH) is a tripeptide composed of glutamate, cysteine, and glycine. It is the body’s primary intracellular antioxidant and detoxifier. It is supplied strictly for laboratory investigation and research purposes, not for human consumption. Our product is the reduced (active) form with ≥99% purity. glutathione peptide for sale

: What purity levels do you guarantee for glutathione?
A: We guarantee ≥99% purity, verified by HPLC testing with Certificates of Analysis available for every batch. Each COA provides detailed purity analysis, mass spectrometry confirmation (307.32 g/mol expected), and batch-specific data.

: What is the CAS number for glutathione?

: What is the molecular weight of glutathione?
A: The molecular weight is 307.32 g/mol .

: What is the difference between reduced and oxidized glutathione?
A: Reduced glutathione (GSH) is the active antioxidant form with a free sulfhydryl group. Oxidized glutathione (GSSG) is formed when two GSH molecules donate electrons and form a disulfide bond. The GSH:GSSG ratio is a key indicator of cellular redox status .

: Why is glutathione called the “master antioxidant”?
A: Glutathione is the most abundant intracellular thiol antioxidant, directly neutralizes free radicals, and regenerates other antioxidants (vitamins C and E) back to their active forms, making it central to the entire antioxidant network .

The Science Behind Glutathione: The Master Antioxidant

Glutathione was first discovered in 1888 by J. de Rey-Pailhade, who identified a substance in yeast that could reduce elemental sulfur to hydrogen sulfide . Its structure was elucidated in 1929 by Hopkins and colleagues, establishing it as the tripeptide γ-glutamylcysteinylglycine . glutathione peptide for sale

The physiological importance of glutathione was established through decades of research demonstrating its essential role in:

• Redox homeostasis: Maintaining the balance between oxidants and antioxidants

• Thiol protection: Preserving protein thiol groups critical for enzyme function

• Detoxification: Conjugating with xenobiotics via glutathione S-transferase

• Immune function: Supporting lymphocyte proliferation and activity

• Mitochondrial integrity: Protecting mitochondrial DNA and membranes from oxidative damage

The synthesis of glutathione occurs in two ATP-dependent steps: (1) γ-glutamylcysteine formation by glutamate-cysteine ligase (GCL), the rate-limiting step; and (2) addition of glycine by glutathione synthetase (GS) . Cysteine availability is the primary limiting factor, making cysteine supplementation (via N-acetylcysteine) a common strategy to boost GSH levels . glutathione peptide for sale

Glutathione depletion is a hallmark of oxidative stress and is associated with numerous pathological conditions, including:

• Neurodegenerative diseases (Alzheimer’s, Parkinson’s, Huntington’s)

• Cardiovascular diseases (atherosclerosis, heart failure)

• Metabolic disorders (diabetes, fatty liver disease)

• Aging and age-related decline

• Immune dysfunction

The GSH:GSSG ratio is considered one of the most reliable indicators of cellular redox status, making glutathione a critical endpoint in oxidative stress research.
