ID 8100
Name peptide derived from oyster (Crassostrea gigas)
sequence
LKQELEDLLEKQE

Function:
Peptide exhibited the higher activity against polyunsaturated fatty acid (PUFA) peroxidation than that of a-tocopherol (84,9%). It was also "effectively quenched radicals in the order of hydroxyl and superoxide radical, with the IC50 values at 28.76 and 78.79 µM, respectively. Hydroxyl radical and superoxide radicals were scavenged at 87.78% and 48.36%, respectively in the presence of 0.1 mg/ml concentration of the purified peptide".
