WebSep 2, 2024 · 3.1. Formation of Disulfide Bonds. Figure 2 summarizes the strategies for constructing disulfide-crosslinked hydrogels. Traditionally disulfide formation results from the oxidation of thiols exposed to molecular oxygen in ambient air or mild oxidizing reagents such as Cu (II)SO 4 ( Figure 2 A). WebThe result is a weak dipole-dipole interaction that can occur in thiols rather than the more powerful hydrogen bond of an alcohol. The properties of thiols are influenced … WebHydrogen bonds are a special type of dipole-dipole forces. In hydrogen bonding, the dipole-dipole attraction occurs between hydrogen and a highly electronegative atom (O,F,Cl,etc). Hydrogen bonds are much stronger than a general dipole-dipole force.These are the only differences, otherwise everything is same. I hope this helps. ( 23 votes) Upvote lynching picnic
