These peptides can modulate the proliferation of human lymphocytes down regulate the production of certain cytokines and stimulate the phagocytic activities of macrophages.
Bioactive peptides definition. Peptides from greek language peptos peptos digested. Bioactive peptides bp are organic substances formed by amino acids joined by covalent bonds known as amide or peptide bonds. Bioactive peptides are protein fragments which have a positive impact on the functions and conditions of living beings.
Bioactive peptides from caseins and whey proteins are also known to have immunomodulatory effect. Upon oral administration bioactive peptides may affect the major body systemsnamely the cardiovascular digestive immune and nervous systems. Bioactive definition is having an effect on a living organism.
Bioactive peptides are proteins synthesized in the cell in the form of large prepropeptides which are then cleaved and modified to give active products. Bioactive food as dietary interventions for diabetes is the only available scientific resource focused on exploring the latest advances in bioactive food research and the potential benefit of bioactive food choice on the diabetic condition. As signaling molecules the bioactive peptides play important roles in physiological functions and pathogenesis.
The simplest peptides are dipeptides followed by tripeptides tetrapeptides etca polypeptide is a long continuous and unbranched peptide chain. Derived from pessein pessein to digest are short chains of amino acids linked by peptide bonds. Bioactive peptides have been defined as specific protein fragments that have a positive impact on body functions or conditions and may ultimately influence health.
Peptides have shown several useful properties for human health including antimicrobial antifungal antiviral and antitumor activities. How to use bioactive in a sentence. A variety of naturally formed bioactive peptides have been found in fermented dairy products such as yoghurt sour milk and cheese.
The health benefits attributed to peptides in these traditional products have so far not been established however. Although some bp exist free in its natural source the vast majority of known bp are encrypted in the structure of the parent proteins and are released mainly by enzymatic processes.
