Q1. What are the contributions mentioned in the paper "Novel whey-derived peptides with inhibitory effect against angiotensin-converting enzyme: in vitro effect and stability to gastrointestinal enzymes" ?
In this paper, a wheat protein concentrate ( WPC ) was subjected to enzymatic hydrolysis by proteases from the flowers of Cynara cardunculus, and the resulting angiotensin-converting enzyme ( ACE ) -inhibitory effect was monitored.
