Conditions & Health

Oxidative stress

An imbalance between free radical production and antioxidant defenses, causing cellular damage. Mitochondrial peptides (SS-31, MOTS-c, Humanin) and GHK-Cu reduce oxidative stress through different mechanisms.

Frequently Asked Questions

What is Oxidative stress?

Why is Oxidative stress important in peptide research?

Understanding oxidative stress is important because it represents a health condition where peptide interventions are being actively researched. Knowledge of the underlying pathology helps inform peptide selection and protocol design.

Related Terms

Mitochondrial dysfunction

Impaired mitochondrial function leading to reduced cellular energy (ATP) production. Contributes to aging, neurodegeneration, and metabolic disease. Targeted by mitochondria-derived peptides SS-31, MOTS-c, and Humanin.

Inflammation

The body’s immune response to injury, infection, or irritation. Acute inflammation is protective; chronic inflammation drives disease. Many peptides (BPC-157, KPV, LL-37, Thymosin Alpha-1) modulate inflammatory pathways.

Oxidation

A chemical reaction that can damage methionine and cysteine residues in peptides, reducing activity. Oxidation is accelerated by light, heat, and oxygen exposure. Prevented by proper storage in amber vials with desiccant.

Related Peptide Profiles

SS-31

Elamipretide, a mitochondria-targeted tetrapeptide that stabilizes cardiolipin in the inner mitochondrial membrane to restore cellular energy production.

MOTS-c

A mitochondria-derived peptide that regulates metabolic homeostasis by activating AMPK. Studied for exercise mimetic effects and metabolic health.

Humanin

A mitochondria-derived peptide with cytoprotective and neuroprotective properties. Studied for Alzheimer’s disease and age-related cellular stress.

GHK-Cu

A naturally occurring copper-binding tripeptide that stimulates collagen synthesis, modulates over 4,000 genes, and declines with age.
