Thiol bonding
WebThiols are nucleophiles meaning they are electron donors. This property gives thiols their antioxidant and anticarcinogen properties. For example, thiols can prevent the carcinogenic effects of aflatoxin B1 “AFB1” which can occur in three ways: The thiol interacts with the 2,3-double bond of AFB1 creating a thiol adduct. WebApr 11, 2024 · In the chemical synthesis of conotoxins with multiple disulfide bonds, the oxidative folding process can result in diverse disulfide bond connectivities, which presents a challenge for determining the natural disulfide bond connectivities and leads to significant structural differences in the synthesized toxins. Here, we focus on KIIIA, a μ-conotoxin …
