antimicrobial-peptide-database-apd Antihypertensive peptides represent a fascinating area of research, focusing on naturally occurring short chains of amino acids derived from food proteins that can help regulate blood pressure. These bioactive peptides offer a promising avenue for managing hypertension, a widespread health concern.Natural Antihypertensive Peptides: Emerging Therapeutics ... Their mechanism of action often involves interfering with the renin-angiotensin system (RAS), a key hormonal cascade that controls blood pressure2025年8月10日—Our results suggest that the LC-MS method is an appropriate analytical method to specifically quantify the anti hypertensivepeptides, Val-Pro- .... Specifically, some antihypertensive peptides work by inhibiting angiotensin-converting enzyme (ACE) or by blocking the interaction between angiotensin II and its receptors, thereby promoting vasodilation and reducing blood pressure. The quest for effective and safe antihypertensive peptide sources spans across various food categories, including dairy, meat, eggs, fish, and even plant-based proteins, with ongoing research identifying novel peptides with significant blood pressure-lowering activity.Quantitative analysis of the antihypertensive peptides Val- ...
Antihypertensive peptides are generated through the enzymatic hydrolysis of larger food proteins. This process can occur naturally during digestion or be intentionally induced through industrial methods using enzymes like pepsin, trypsin, or alcalase.
* Animal-Derived Peptides: A significant portion of research focuses on peptides sourced from animal proteins. Dairy products, particularly milk and whey, are rich sources, with well-studied peptides like Valyl-Prolyl-Proline (VPP) and Isoleucyl-Prolyl-Proline (IPP) demonstrating clinically relevant blood pressure-lowering effects. Proteins from meat, eggs, and fish also yield antihypertensive peptides. For instance, studies have identified potent peptides from chicken and bovine casein.
* Plant-Derived Peptides: Plant proteins are increasingly recognized for their potential to yield antihypertensive peptides. Sources include legumes like mung beans and soybeans, as well as cereals and seeds. For example, peptides derived from vicilin, a major storage protein in mung beans, have shown promise. Low molecular weight plant peptides, generally less than 3 kDa, are often considered more effective antihypertensive agents.
* Marine-Derived Peptides: Proteins from marine organisms, including fish, also serve as a source for bioactive peptides with antihypertensive properties.
The primary mechanisms by which antihypertensive peptides exert their effects primarily target the renin-angiotensin system (RAS):
* Angiotensin-Converting Enzyme (ACE) Inhibition: Many antihypertensive peptides function as ACE inhibitors. ACE is responsible for converting angiotensin I to angiotensin II, a potent vasoconstrictor. By inhibiting ACE, these peptides reduce the production of angiotensin II, leading to vasodilation and a decrease in blood pressure. Specific peptides like LAP have been noted for this activity.
* Angiotensin Receptor Blockade: Some peptides can directly block the binding of angiotensin II to its receptors on blood vessels and other tissues.Antihypertensive peptides from animal products, marine ... This blockade prevents angiotensin II from initiating its vasoconstrictive effects, contributing to lower blood pressure.
* Other Mechanisms: Emerging research suggests that antihypertensive peptides may also influence other physiological pathways, such as modulating nitric oxide production, exhibiting antioxidant properties, or influencing lipid metabolism, which can indirectly contribute to cardiovascular healthAntihypertensive Peptides Derived from Bovine Casein ....
