Hydrophobic bonds
WebCovalent bonds are strong and, in many cases, not reversible under biologic conditions. Electrostatic bonds are weaker than covalent bonds, more common, and often reversible. Hydrophobic bonds are the weakest and are probably the most important in the interactions of lipid-soluble drugs and in hydrophobic “pockets” of receptors. Web14 apr. 2024 · Gluten is a natural byproduct derived from wheat starch, possessing ideal biocompatibility. However, its poor mechanical properties and heterogeneous structure are not suitable for cell adhesion in biomedical applications. To resolve the issues, we prepare novel gluten (G)/sodium lauryl sulfate (SDS)/chitosan (CS) composite hydrogels by …
