The Effects of Dissolved Hydrophobic and Hydrophilic Groups on Water Structure

Directional nature of hydrophobic interactions: Implications for the mechanism of molecular recognition

“…As a solute is dissolved into water, the interface can be expected to occur between the solute and water, which undoubtedly affects the structure of water. Based on the structural studies on water and air/water interface [17][18][19][20], hydration free energy is derived, and utilized to investigate the origin of hydrophobic interactions [21][22][23][24][25]. In our recent studies [21,22], with reference to Rc (critical radius), it can be divided into initial and hydrophobic solvation processes.…”

Terahertz Absorption Characteristics of the Sodium Carboxymethyl Cellulose Colloid Based on Microfluidic Technology

“…is electrostatic force is called a hydrogen bond. ere are many carboxyl groups (-COOH) and hydroxyl groups (-OH) in CMC-Na macromolecules [13], and carboxyl and hydroxyl groups can form hydrogen bonds with water molecules [14]. A new hydrogen bond was formed between the CMC-Na macromolecule and the water molecule, which reduced hydrogen bonding between water molecules.…”

“…erefore, in this study, the influence of Na + can be excluded. Sun [14] studied the influence of hydrophobic and hydrophilic groups on the water structure by Raman spectroscopy, and the obtained results showed that adding hydrophilic groups affected hydrogen bonds in water. Wen International Journal of Optics et al [16] determined that a hydrogen bond could be formed between CMC-Na and silk fibroin protein, which reduced hydrogen bonding between silk fibroin protein molecules.…”
