Question

The cytoplasm has a reducing environment, while the extracellular space tends to have an oxidizing environment. Based on this information, where would proteins with disulfide bonds most likely be synthesized?

Answer 1

In the extracellular space

Step-by-step explanation:

Disulfide bonds are interconnections between chains (or between parts of a chain) formed by the oxidation of cysteine ​​radicals, this reaction is catalyzed by specific enzymes.

Intracellular proteins have no disulfide bonds, which are more common in proteins secreted into the extracellular environment.

Disulfide bonds do not form in the cytoplasm because there are a lot of reducers in the cytoplasm (intracellular environment) , making the disulfide bonds unstable. The reducing environment of cytoplasm causes disulfide bonds (S-S) to return to the form of cysteine ​​groups (-SH).
