Preparation method
Mode of preparation Enzymatic hydrolysis
Enzyme(s)/starter culture Algae protein waste was hydrolyzed with Pepsin.
Stability & Cytotoxicity
Peptide stability
Literature report:

The purified hendeca-peptide completely retained its ACE inhibitory activity at a pH range of 2–10, temperatures of 40–100 °C, as well as after treatments in vitro by a gastrointestinal enzyme, thus indicating its heat- and pH-stability.

Additional information
Additional information

(1) Algae protein waste is a by-product during production of algae essence from Chlorella vulgaris.
(2) The combination of the biochemical properties of this isolated hendeca-peptide and a cheap algae protein resource make an attractive alternative for producing a high value product for blood pressure regulation as well as water and fluid balance.
