Scientists found a new small protein piece from a desert plant’s seeds by filtering the broken-down proteins to find the ones that fight oxidation.
Scientific Claim
A novel decapeptide sequence, QITEGEDGGG, was purified from Caragana ambigua seed protein hydrolysate using high-performance liquid chromatography based on antioxidant enrichment.
Original Statement
“A novel decapeptide, identified as QITEGEDGGG, was purified by high‐protein liquid chromotography based on the enrichment of antioxidant fractions...”

Isolation of antioxidative peptide from the protein hydrolysate of <i>Caragana ambigua</i> seeds and its mechanism for retarding lipid auto‐oxidation
Scientists found a tiny protein piece called QITEGEDGGG in a plant’s seeds, pulled it out using a special cleaning method that picks out antioxidant stuff, and proved it fights harmful oxidation — exactly what the claim says.
