Abstract
Biologically active peptides are the general term for different peptides which constitute different compositions and arrangements of natural amino acids. They are known to possess a variety of biological functions such as antioxidant, immune-promoting, hormone-modulating, antibacterial, antithrombotic, antiviral, and antihypertensive activities due to multifunctional compounds derived from animal or plant proteins. Moreover, they have high food safety and high bioavailability which make them potential candidates for the development of functional peptide drugs and functional food additives. ACE (angiotensin-converting enzyme) inhibitory peptides found in nature could be used as antihypertensive ingredients in functional foods or nutraceuticals. These peptides have been found in a variety of plant and animal protein-based foods. The ACE inhibitory peptides produced by enzymatic hydrolysis of protein from various sources are discussed in this work. Some of these peptides have antihypertensive effects in spontaneously hypertensive rats, as well as in vitro ACE inhibitory activity. This review discusses the advances in the enzymatic preparation of bioactive peptides from various sources exhibiting ACE activity, highlighting the growing interest in bioactive peptides as part of the diet and the rising prevalence of the noncommunicable disease of hypertension.
