Human chorionic gonadotropic (hCG) and human placental latogen (hPL) are peptide hormones produced and excreted by placental trophoblastic cells during pregnancy.

In this study, zein, a very abundant and cheap crop in China was hydrolyzed by thermolysin, chymotrypsin, trypsin and alkaline protease for processing antihypertensive peptides.
Arginine vasopressin(AVP) is a kind of introgenic nine peptide hormone,which was traditional applied in diabetes insipidus and rhexis bleeding caused by acute esophageal varix.
Defensin,existing in the right arm of the second chromosome of drosophila melanogaster,encodes a product which possesses an anti-bacterial peptide activity and resists Gram-positive bacteria.
The assay begins with a standard kinase reaction performed in the provided Reaction Buffer with a provided Bisamide Rhodamine 110 peptide substrate (PKA R110 Substrate).
The “Jinguihuishengyi” contains an antiepileptic peptide separated from ophidic toxin, and can resist the epilepsy of rats caused by cephalosporin and coriamyrtin.
Intein is an intervening polypeptide which can catalytic self-cleavage from a pre-protein accompanied by the concomitant joining of the two flanking polypeptides (the extein) through a peptide bond.
There’s also pancreatic amylase which breaks down carbohydrates into shorter oligosaccharides, and proteases, like trypsin, which cleaves proteins down into smaller peptides.
