Role of the Maillard reaction products of oyster peptides and chitosan oligosaccharide in chelation with zinc: restoring testicular injury and the testosterone synthesis pathway

; SOD: 105.60 U per mgprot) and reduced inflammatory gene expression (IL-1β, IL-6, TNF-α). MOCZn also reversed zinc deficiency-induced dysregulation of testosterone synthesis genes (downregulated P450SCC, StARD7, HSD17B3; upregulated StAR), mitigating testicular damage (testosterone levels).
