Structure and Composition: Peptides are short proteins that can adopt various secondary structures (e.g., \(\alpha \)-helix, \(\beta \)-sheet) necessary for biological activity.
High Purity and Potency: Pharmaceutical-grade peptides (often >98–99% purity) are produced to meet stringent standards, requiring a manufacturer's Certificate of Analysis (COA) to confirm quality.
Physical State: They are commonly supplied as [lyophilized powder] (freeze-dried), which increases stability over long periods compared to liquid form.
Hygroscopicity: Peptide powders often have high moisture absorption, necessitating storage in a cool, dry, and dark place to maintain stability.
Metabolic & Weight Loss Management: Widely used in producing glucagon-like peptide 1 (GLP-1) receptor agonists, such as liraglutide and semaglutide, to treat type 2 diabetes and obesity.
Oncology Research & Therapy: Peptides are used as targeted therapies to treat various cancers, accounting for a significant portion of peptide market applications.
Cosmeceuticals & Anti-Aging: Peptide powders (e.g., GHK-Cu) are added to topical serums and creams to boost collagen synthesis, enhance fibroblast proliferation, reduce pigmentation, and improve skin barrier function.
Infectious Diseases: Used to produce antiviral drugs (e.g., enfuvirtide for HIV-1) and antimicrobial agents (e.g., teicoplanin for MRSA infections).
