Description: AHK-Cu (Copper Tripeptide-3) is a synthetic metallo-peptide coordination complex combining the tripeptide L-alanyl-L-histidyl-L-lysine with copper(II).In biochemical and dermal research models, it is utilized to study extracellular matrix remodeling and vascular endothelial growth factor (VEGF) expression. Laboratory investigations primarily focus on its influence over fibroblast activity, collagen type I synthesis, and the physiological signaling pathways within isolated follicle cell cultures.
