The sets of amino acids which facilitate chemical modification leading to improved protein functionalities
EXPLANATION
Fish Muscle Proteins & Structural Biochemistr
- Chemical Modification of Fish Proteins:
- The side-chain functional groups of specific amino acids facilitate chemical modifications to improve solubility, emulsification, and gel-forming functional properties:
- Lysine (Lys): Possesses an accessible reactive $\varepsilon$-amino group ($-NH_2$) for acylation, succinylation, and phosphorylation.
- Cysteine (Cys): Possesses a reactive sulfhydryl ($-SH$) group for disulfide cross-linking and redox tailoring.
- Tryptophan (Trp): Contains an electron-rich indole ring susceptible to mild chemical modification.
- Correct Option: Option 3 (Lys, Cys, Trp).
