Structural properties and stability of the Betaine-Urea natural deep eutectic solvent

Betaine as a Functional Ingredient: Metabolism, Health-Promoting Attributes, Food Sources, Applications and Analysis Methods

“…Being an excellent protein stabilizer in various organisms and a hydrogen bond acceptor, betaine is an important component of various mixtures of deep eutectic solvents (DES) and natural deep eutectic solvents (NADES) that have found numerous applications as green alternatives in the extraction procedures of various raw materials, thus replacing organic solvents, which may have harmful effects on humans and the environment [ 118 , 119 , 120 , 121 ]. These are less toxic and highly biodegradable; their preparation is simple and inexpensive; and they have demonstrated a high potential for extracting the natural compounds.…”

Facile green synthesis of a dahlia-like anatase/TiO2(B) phase junction for boosting the photocatalytic degradation of persistent tetracycline

“…These changes are mainly ascribed to the formation of H-bonds between H of –NH 2 in urea and O of carboxylate (COO) in betaine, and between H of –OH in oxalic acid and O of COO in betaine. 22,25 Moreover, Fig. 1b indicates the changes in bond lengths of major functional groups before and after forming the DES.…”
