Lauryldimethylamine oxide Lauryldimethylamine oxide Lauryldimethylamine oxide (LDAO), also known as dodecyldimethylamine oxide (DDAO), is an amine oxide based nonionic surfactant, with a C (dodecyl) alkyl tail. It is one of the most frequently-used surfactants of this type. Like other amine oxide based surfactants it is antimicrobial, being effective against common bacteria such as "S. aureus" and "E. coli", however it is also non-denaturing and may be used to solubilize proteins. At high concentrations, DDAO forms liquid crystalline phases. Despite having only one polar atom that is able to interact with water – the oxygen atom (the quaternary nitrogen atom is hidden from
Dihydrogen bond via dihydrogen bonding. This kind of H−H interaction is distinct from the H−H bonding interaction in transition metal complexes having dihydrogen bound to a metal. So-called hydrogen hydrogen bond interactions have been proposed to occur between two neutral non-bonding hydrogen atoms from Atoms in molecules theory, while similar interactions have been shown to exist experimentally. Many of these types of dihydrogen bonds have been identified in molecular aggregates. Dihydrogen bond In chemistry, a dihydrogen bond is a kind of hydrogen bond, an interaction between a metal hydride bond and an OH or NH group or other proton donor. With a
