Natural endogenous origin is the essential origin of Humanin.
In 2001, Japanese researchers first isolated this peptide from the undamaged occipital cortex of Alzheimer's patients. Its encoding gene is hidden within the mitochondrial 16S ribosomal RNA gene (mt-rnr2), a special "gene within a gene," and one of the trace peptides directly encoded by the mitochondrial genome. It is mainly synthesized in highly metabolic tissues of the human body, such as the brain, myocardium, and pancreas, and its synthesis location determines its amino acid length-21 amino acids are synthesized in mitochondria, and 24 amino acids are synthesized in the cytoplasm; both forms possess biological activity.https://www.fiercerawsource.com/peptides/premium-high-purity-peptides-humanin.html
It is noteworthy that the expression level of natural humanin decreases with age, and is even lower in patients with chronic diseases, while it is highly conserved in long-lived species such as naked mole-rats and nematodes. This has become an important entry point for its anti-aging research.
Artificial exogenous preparation is currently the main source for industry applications. Due to the difficulty and low purity of natural extraction, the industry mainly uses the FMOC solid-phase synthesis method, which solves the problem of synthesizing "difficult sequences" by precisely controlling the splicing of amino acid sequences to obtain high-purity products; a small amount is produced using gene engineering expression technology, utilizing host cells to achieve large-scale production. Artificially prepared humanin can accurately replicate the activity of natural peptides, with higher purity and stronger stability, and is widely used in neuroprotection, metabolic regulation, and other related scientific research and product development, becoming one of the hot research directions in the peptide industry.
