Abstract
The present study aimed to characterise anti-oxidant peptides from water-soluble
protein extracts of Hanwoo beef and evaluate their anti-proliferative effect on
human colorectal carcinoma cells (HCT116). Antioxidant peptides were purified
from the low-molecular-weight fraction (<3 kDa) of Hanwoo beef extract.
Antioxidant activity of peptide fractions was determined using the oxygen
radical absorbance capacity (ORAC) assay. Purified peptide (P3) displayed higher
ORAC activity than the low-molecular-weight fraction (202.66 μM TE/g vs
167.38 μM TE/g of dry matter, respectively) (p<0.05). The peptide
sequence of P3 was Cys-Cys-Cys-Cys-Ser-Val-Gln-Lys (888.30 Da). The novel
peptide P3, at 250 μg/mL, also significantly inhibited HCT116 cell
proliferation up to 25.24% through phosphorylation of ERK, JNK, and p38 kinase
(p<0.05). Hence, antioxidant peptide P3 from Hanwoo beef extract can be
used as an antioxidative and anti-cancer agent in the functional food
industry.
