Cockroach hemolymph exhibited high concentrations of aspartic acid, glutamic acid, and serine, which are essential for arthropod survival and metabolism. This finding contrasts with , who reported an absence of aspartic acid and cystine in Blaberus discoidalis hemolymph. However, differences in cockroach species between the studies may account for this discrepancy. Sankar and Yogamoorthi (2012) also identified 14 amino acids in the hemolymph and muscles of both sexes of Ocypode platytarsis, with findings similar to those in the present study.
