Functions of Bioactive Peptides

Bioactive peptides exhibit numerous physiological activities, including antioxidative, antitumor, antimicrobial effects, cholesterol reduction, lipid lowering, and immune enhancement. Their diverse functions are increasingly discovered with deepening research, highlighting their potential in nutrition and therapeutic applications.

Antioxidative Activity

Bioactive peptides can form a biological antioxidant barrier in the body, combating oxidative stress-induced chronic diseases. Since the initial discovery in 1960, numerous peptides with antioxidative functions have been identified, showcasing their potential in health maintenance and disease prevention.

ACE Inhibitory Activity

With hypertension being a prevalent and harmful condition, ACE inhibitory peptides have been recognized for their potential in safe and effective blood pressure management, offering a promising avenue for therapeutic intervention.

Anti-inflammatory Activity

Chronic inflammation can lead to significant tissue damage and health issues. Anti-inflammatory peptides act by modulating immune responses, suggesting their potential in developing safer anti-inflammatory treatments.

Antimicrobial Activity

Given the rise of antibiotic-resistant bacteria, bioactive peptides with antimicrobial properties present an alternative in combating infectious diseases, with advantages including broad-spectrum activity and low toxicity.

Antitumor Activity

Bioactive peptides are investigated for their roles in specifically targeting cancer cells without harming normal bodily functions, providing a hopeful strategy for cancer therapy.

Mineral Absorption Enhancement

Peptides such as casein phosphopeptides (CPPs) show promise in enhancing the absorption of minerals, indicating their potential in addressing mineral deficiencies.

Probiotic Growth Promotion

Certain peptides have been found to support the growth of beneficial gut bacteria, suggesting a role in improving gastrointestinal health and overall wellbeing.

Sources of Bioactive Peptides

Natural Sources

Bioactive peptides are derived from a wide range of sources, including human tissues, animal proteins, plants, microorganisms, and marine organisms, each offering unique structural and functional attributes.

Artificial Synthesis

Due to the challenges in extracting natural peptides, research has shifted towards artificial synthesis, providing an avenue for producing peptides with specific health benefits.

Pea Research Status

Peas, rich in protein, starch, minerals, and vitamins, have been recognized for their high nutritional value and potential health benefits, including blood sugar regulation, cardiovascular health improvement, and cancer risk reduction.
