Sulfhydryl and Disulfide Interactions in Proteins of Biological Systems

Edited by Amit Kumar

Proteins

Proteins are polymers of different amino acids found in biological systems which have certain functional properties to perform the predetermined actions in trigger conditions. I shall not discuss the basics of protein and its functionality in this section. Here, I shall give a glimpse of protein structure and the role of sulfhydryl and disulfide groups in the interactions of the protein with surrounding molecules.

As you can see in the above picture, proteins are made of different amino acids. These amino acids are 20 monomers with low molecular weight but specific functionality due to resonating electron cloud forming alpha and pi bonds. Among all the 20 amino acids, Methionine, cysteine, homocysteine, and taurine are the 4 common sulfur-containing amino acids, but only the first 2 are incorporated into proteins. Thus, the presence of Methionine (met, M) and Cysteine (Cys, C) enables the protein to interact through S- linkage. This S- linkage can form S-H or S-S based on the surrounding environmental condition and specific energy of the protein.
