Description

N6-(1-Oxooctadecyl)-L-Lysine is a chemically modified amino acid derivative where the ε-amino group of L-lysine is acylated with stearic acid. This molecular design is significant for introducing lipophilic, long-chain fatty acid properties onto the lysine backbone, enhancing its compatibility with non-polar matrices. It is primarily needed by researchers and formulators in the pharmaceutical, cosmetic, and advanced material sectors for applications requiring modified biomolecules with tailored amphiphilic characteristics.

Application

• Pharmaceutical Intermediates: Serves as a key building block for synthesizing novel peptide-based drugs or prodrugs, where the lipophilic chain can improve membrane permeability and bioavailability.
• Cosmetic Actives & Surfactants: Used in the formulation of high-end skincare products as a conditioning agent or a mild, amino acid-derived surfactant with skin-friendly properties.
• Bioconjugation & Protein Modification: Acts as a chemical linker or modifier in bioconjugation chemistry to attach hydrophobic labels or functional groups to proteins and peptides.
• Polymer & Material Science: Employed as a monomer or additive to create functional polymers with specific hydrophobic-hydrophilic balance (HLB) for controlled release or specialty coatings.
• Biochemical Research: Utilized as a standard or reagent in lipid metabolism studies and research on fatty acid-amino acid conjugates.
• Nutraceutical Formulations: Investigated for use in advanced nutrient delivery systems where enhanced lipid solubility is required.
