It is formed by the ethoxylation chemical reaction of dodecanol (lauryl alcohol) to give a material with 5 repeat units of ethylene glycol. Multilamellar vesicle formation [ edit ]

A classic laboratory method involves Bouveault-Blanc reduction of ethyl laurate. [4] Dodecanol is used to make surfactants, which are used in lubricating oils, and pharmaceuticals. Millions of tons of sodium dodecylsulfate (SDS) are produced annually by sulfation of dodecyl alcohol: [6] SO 3 + CH 3 (CH 2) 10 CH 2 OH → CH 3 (CH 2) 10 CH 2 OSO 3 H
The page provides a comprehensive list of isomers of dodecane, including their chemical structures and properties.
To ensure that the resin is protonated and positively charged, the chromatography should be performed at least 2 pH units below the pKa of the amine group, 10. The strength of the bond between the resin and protein is highly dependent on the pH range in the column and the pI of the protein of interest.
These periodic sequences are generated by internal duplications in both coding and non-coding genomic sequences. Repetitive units of protein tandem repeats are considerably diverse, ranging from the repetition of a single amino acid to domains of 100 or more residues.

Octyldodecanol is a branched-chain primary alcohol used as the isomer 2-octyl-1-dodecanol in cosmetics such as lipstick, [2] or as an anti-blooming agent in facepowder. [3] It is a medium spreading emollient, with equilibrium spreading pressure of 17.0 dyne/cm. [4] Octyldodecanol is in the class of Guerbet alcohols, because it has the branch at the β position. [5]
The enzyme unit, or international unit for enzyme (symbol U, sometimes also IU) is a unit of enzyme's catalytic activity. [ 1 ] 1 U (μmol/min) is defined as the amount of the enzyme that catalyzes the conversion of one micro mole of substrate per minute under the specified conditions of the assay method .
