Lithium dodecyl sulfate
Lithium dodecyl sulfate

Cat. No.: HY-W099535
CAS No.: 2044-56-6
Lithium dodecyl sulfate is an anionic hydrocarbon surfactant with both surface tension reduction and interfacial adsorption capabilities. Lithium dodecyl sulfate induces low surface viscosity; it forms micelles in aqueous solutions through entropy-driven (low temperature) and enthalpy-driven (high temperature) mechanisms. When acting synergistically with tetrabutylammonium bromide, Lithium dodecyl sulfate exhibits cloud point behavior due to micelle aggregation and phase separation. Lithium dodecyl sulfate can form an adsorption layer at the air-water interface with quantifiable surface excess and minimum area per molecule, and it has higher equilibrium surface tension and foamability compared to other dodecyl sulfate counterion variants. The foam stability of Lithium dodecyl sulfate above its critical micelle concentration is low, and its dynamic surface tension pattern changes dynamically with bubble frequency .

Cat. No.: HY-W096983
CAS No.: 112-00-5
Synonyms: Dodecyltrimethylammonium chloride,for IPC,≥99%
DTAC (Dodecyltrimethylammonium chloride), for IPC, ≥99% is a quaternary ammonium cationic surfactant. DTAC, for IPC, ≥99% can form micelles in aqueous media, which interact with and encapsulate Diclofenac sodium (HY-15037) molecules; the micellization process is entropy-driven at lower temperatures and enthalpy-driven at higher temperatures .

Amyloid-Forming peptide GNNQQNY is a biological active peptide. (This is a heptapeptide from the N-terminal prion-determining domain of the yeast protein Sup35 that forms amyloid fibrils. The availability of its detailed atomic oligomeric structure makes it a good model for studying the early stage of aggregation. The GNNQQNY dimer forms three stable sheet structures. in-register parallel, off-register parallel, and anti-parallel. The in-register parallel dimer, which is close to the amyloid beta-sheet structure, has few interpeptide hydrogen bonds, making hydrophobic interactions more important and increasing the conformational entropy compared to the anti-parallel sheet.)
