Fish protein hydrolysates: Proximate composition, amino acid composition, antioxidant activities and applications: A review
TL;DR: Fish protein hydrolysates are breakdown products of enzymatic conversion of fish proteins into smaller peptides, which normally contain 2-20 amino acids, and have attracted much attention of food biotechnologists due to the availability of large quantities of raw material for the process.

Antioxidant and free radical-scavenging activities of chickpea protein hydrolysate (CPH)
TL;DR: In this paper, chicken protein hydrolysate (CPH) was fractionated by gel filtration on Sephadex G-25 and the antioxidant and free radical-scavenging activities of four CPH fractions were measured using reducing power, inhibition of linoleic acid autoxidation, and 1,1-diphenyl-2- pycrylhydrazyl (DPPH)/superoxide/hydroxyl radical scavenging assay.

Antioxidative Properties of Histidine-Containing Peptides Designed from Peptide Fragments Found in the Digests of a Soybean Protein
TL;DR: Although the histidine-containing peptides had a quenching activity on singlet oxygen, they did not show antioxidative activity in an 2,2'-azobis(2,4-dimethylvaleronitrile)-induced oxidation system or scavenging effects on 1,1-diphenyl-2-picrylhydrazyl radical and superoxide.

Antioxidation action of indole compounds during the autoxidation of linoleic acid
H Mistuda,K Yuasumoto,K Iwami +2 more
TL;DR: In this article, the authors found that the antioxidative activity of aromatic amino acids and indole compounds for the autoxidation of linoleic acid was correlated with the highest occupied molecular orbital energy which represents the electron donor property of respective molecule.
