Hydroxyl Group Stereochemistry Effect on Sugar Surfactant Dialkylchains (bicatenaries)

What is it about?

This paper contains among the most important results of our investigation to screening interfacial properties of Carbohydrate-Bio-based Surfactants (CBS), prepared from renewable resources, in order to search new properties and performances, but also to understand their behavior, and predict their potential uses by means of chemical structure-activity correlation approaches.

Why is it important?

Here, we show and explain differences observed between dimyristoyl (C14/C14) of galacturonic (galA) and glucuronic acid (glcA), two uronic acid (sugar acids) stereoisomers by investigating, in detail, mechanical (compressibility, stability) and optical (morphology, relative thickness) properties of their monolayers spread at the Air-Water interface. Such bio-based compounds with interesting film mechanical and optical properties would be valuable, for instance, in colloidal system areas.
