The intensity of the yellow color is directly proportional to the concentration of thiol groups present in the sample
Early studies detected a loss of the antibacterial activity of penicillin induced by cysteine, which was attributed to chemical reactions involving the thiol and/or amino groups of the amino acid ( 1 H-NMR, is the first detectable product in the reaction, which subsequently undergoes hydrolysis to the benzylpenicilloic acid ( Figure 3B ) ( The six-membered ring to which the -lactam is fused in cephalosporins, results in lower tension within the -lactam ring compared to those of penicillins, and therefore less reactivity against thiolate anions ( 2 chemical structure can modulate this reactivity depending on its ability to polarize the electronic binding ( Figure 4 and Figure S5 )
