The nervous system regulates cognition, emotion, and bodily functions through complex neurotransmitter networks and cellular signaling pathways. Damage or degeneration within this system can lead to major health issues such as Alzheimer’s disease, Parkinson’s disease, anxiety, depression, and neural trauma. Core pathways for maintaining neurological and cognitive health—including neuroprotection, cognitive enhancement, emotional regulation, and neural injury repair—rely on precise interventions in neuronal survival, synaptic plasticity, neuroinflammation, and regenerative mechanisms. Peptide substances, with their high biological activity and blood-brain barrier permeability, have emerged as ideal molecules for targeting neural pathways. They delay neurodegeneration at the cellular level and promote functional repair, opening new directions for the prevention and treatment of neurological disorders. Read More

Peptide synthesis refers to the process of constructing amino acid sequences and forming amide bonds (i.e., peptide bonds) through chemical or biological means, essentially enabling the artificial construction of oligopeptide or polypeptide molecules with specific biological functions. As a critical branch of bioorganic chemistry, this technology focuses on the selective activation of amino acid monomers, directional conjugation, and precise control of sequence assembly, spanning the full spectrum from milligram-scale laboratory preparation to kilogram-scale industrial production. Based on divergent synthetic strategies, it is classified into biosynthetic methods relying on biological systems and chemical synthesis methods grounded in organic synthesis principles. Read More

The term "peptide" originates from the Greek word "πέσσειν" (péssein), meaning "to digest." A peptide is a compound formed by amino acids linked through peptide bonds. Peptide bonds, which are amide bonds, arise from the dehydration condensation between the α-carboxyl group of one amino acid and the α-amino group of another. Classified by amino acid count, peptides with 2 to 20 amino acids are termed oligopeptides, those with 20 to 50 are polypeptides, and sequences exceeding 50 amino acids with specific spatial structures are generally categorized as proteins. Peptides typically have a molecular weight below 10 kDa. Read More

Research peptides are functionally designed molecules synthesized in laboratories, whose core value lies in providing instrumental support for life sciences research and being exclusively utilized in in vitro research settings. "In vitro research," derived from the Latin term "in vitro" (meaning "in glass"), specifically refers to studies conducted in artificially controlled experimental environments, such as cell culture, molecular interaction analysis, or biochemical reaction assays.

A peptide bond is a characteristic covalent bond in protein molecules, formed through a dehydration condensation reaction between the α-carboxyl group (α-COOH) of one amino acid and the α-amino group (-NH₂) of an adjacent amino acid. Its chemical nature is an amide bond. Read More
