Cysteine peptide
Based on 1 Customer Validation
Cysteine peptide is a tyrosinase inhibitor with skin-whitening, antioxidant and multi-regulatory activities. Cysteine peptide inhibits enzyme activity and blocks melanin transport, effectively reducing UV-B-induced skin erythema and pigmentation. Cysteine peptide synergistically maintains skin health by quenching ROS, resisting oxidative stress and promoting pheomelanin production. Cysteine peptide safely prevents daily ultraviolet damage and supports moderate sun exposure for vitamin D synthesis. Cysteine peptide also acts as a plant signaling factor to regulate vegetative growth, development and stress resistance responses.

Description
In Vitro
Cysteine peptides, including γ-glutamylcysteine and cysteinylglycine, contribute to enhanced DPPH radical scavenging capacity relative to an equivalent amount of GSH alone[1].
Tobacco cysteine peptide RALF inhibits root growth and nutrient uptake in tobacco cells[2].
Tomato cysteine peptide LeRALF induces medium alkalinization in tomato cells via receptor binding, with disulphide bridges essential for activity, and binds to cell surface sites with a dissociation value of 0.8×10-9 M[2].
