Overview
Polypeptide tablets consist of short chains of 2–50 amino acids, synthesized or extracted for targeted biological functions. Unlike proteins, their small size allows efficient absorption and precise modulation of cellular processes. In B2B markets, they are supplied as raw materials for cosmetics, dietary supplements, or pharmaceutical formulations. Common types include copper peptides (skin regeneration), glutathione (antioxidant), and collagen peptides (joint health). Their efficacy depends on sequence design, purity, and delivery systems, making sourcing from specialized manufacturers critical.
Physical and Chemical Properties
Polypeptides exhibit properties dictated by their amino acid sequence. Hydrophilic peptides dissolve readily in water, while hydrophobic variants require organic solvents. They are sensitive to temperature, pH, and enzymatic degradation, necessitating lyophilization or enteric coatings for stability. Mass spectrometry and HPLC are standard for verifying molecular weight and purity (typically ≥95%). Shelf life ranges from 6–24 months under refrigerated storage. Tableting often involves excipients like microcrystalline cellulose to enhance stability.
Main Applications
In skincare, polypeptides like palmitoyl pentapeptide-4 stimulate collagen production, reducing wrinkles. Nutraceutical tablets incorporate branched-chain amino acids (BCAAs) for muscle recovery. Medical applications include thymosin alpha-1 for immune modulation. B2B buyers should align peptide selection with end-use: cosmetic-grade peptides prioritize penetration enhancers, while oral supplements focus on bioavailability. Emerging uses include antimicrobial peptides (AMPs) for preservative-free formulations.
Safety and Storage
Most peptides are non-toxic but require allergen testing for topical applications. Avoid prolonged exposure to heat or humidity to prevent hydrolysis. Lyophilized peptides are stable at –20°C; tablets should be stored in blister packs with desiccants. Regulatory compliance varies: FDA-approved peptides (e.g., glucagon) require stringent documentation, while cosmetic peptides follow less rigorous standards. Always request SDS and stability data from suppliers.
B2B Procurement Guide
Key considerations include minimum order quantities (often 1–10 kg for custom sequences), lead times (4–12 weeks for synthesis), and purity certifications. Reputable suppliers provide COAs with HPLC traces and mass spec data. Bulk pricing drops significantly at 10+ kg orders. For cost-sensitive projects, consider generic peptides like glutathione. Audit suppliers for GMP compliance and batch-to-batch consistency.
