#### What are Biologically Active Peptides?

At their core, biologically active peptides are defined by their functional impact. Unlike generic protein fragments, these peptides are recognized for their capacity to influence biological systems. They are typically short, ranging from two to forty amino acids in length, and are formed by amino acids linked by peptide bonds.作者：A Alzaydi·2023·被引用次数：37—Bioactive peptides (BPs) arechains of amino acids linked together by peptide bondsand arranged in a specific way. These small molecules can be found naturally within food sources, released from parent proteins during digestion or processing, or synthesized for specific research and therapeutic purposes. Their significance lies in their ability to positively influence physiological processes, leading to a wide array of health benefits.

#### Sources and Generation of Bioactive Peptides

Bioactive peptides originate from a variety of sources, with food proteins being a particularly rich reservoir. When proteins found in milk, soy, eggs, meat, and fish undergo enzymatic hydrolysis, fermentation, or gastrointestinal digestion, they can release these smaller, active peptide fragments. For instance, milk proteins like casein and whey are well-known sources of bioactive peptides with various health-promoting properties.

Beyond dietary sources, bioactive peptides can also be generated through specific biotechnological processes.Bioactive Peptides: Functional Roles, Mechanisms, and ... Enzymatic hydrolysis, using enzymes derived from plants, microorganisms, or even digestive enzymes, is a common method for releasing these peptides from precursor proteins作者：AA Zaky·2022·被引用次数：423—Bioactive peptides areprotein fragments that benefit the body systems and overall human health. Most bioactive peptides range between two (dipeptides) and 20 .... This controlled generation allows for the isolation of specific peptides with targeted biological activities, making them valuable tools in research and potential therapeutic development.

#### Key Properties and Functions

The "bioactivity" of these peptides stems from their unique amino acid sequences and three-dimensional structures, which allow them to interact with specific biological targets. These interactions can lead to a diverse range of physiological effects, including:

* Antioxidant Activity: Many bioactive peptides can neutralize free radicals, protecting cells from oxidative damage.

* Antihypertensive Effects: Some peptides can inhibit enzymes involved in blood pressure regulation, contributing to cardiovascular health.

* Antimicrobial Properties: Certain peptides can disrupt bacterial cell membranes, offering a natural defense against pathogens.

* Immunomodulation: Bioactive peptides can influence the immune system, enhancing immune competence or regulating inflammatory responses.

* Mineral Binding: They can form complexes with minerals like calcium and zinc, improving their bioavailability and absorption.作者：T Dang·2017·被引用次数：176—This Account predominantly highlights recent discoveries, approaches, and research from our laboratory on RiPPs and NRPSs from bacteria and fungi.

* Hormonal Regulation: Some peptides mimic or influence the action of hormones, impacting processes like satiety and metabolism.

#### Applications and Future Potential
