Types Of Peptides And Their Physiological And Nutritional Effects

Mar 31, 2015

Peptides from its functionality can simply be divided into 2 types: the functionality of small peptide and nutrition of small peptide. Nutrition of small peptide refers to only as raw materials and conducive to the absorption of amino acids of the protein synthesis but does not have some other bioactive peptides. Bioactive peptides and refers to an organism life activity with special physiological activity of a large class of peptides. Produced by the organism's own tissues or organs on their own have a physiological effect of a peptide called endogenous bioactive peptides; rather than produced by the body itself, in the form of peptide is absorbed by biologically active peptides called exogenous peptides mainly plays a regulating body digestive system, nervous system, endocrine system and immune function of biological activity. Recent studies have shown that small peptide in animal nutrition and Physiology plays an important role:

1.1 small peptide can promote the absorption of amino acids and minerals. Peptide is absorbed differently in the absorption of amino acids, which is faster, less prone to saturation, avoids competing with amino acids, and other characteristics, which helps the body to absorb, this has been proven in many trials. Such as Shi Yonghui small peptides and free amino acids in different proportions when the effects on the absorption of amino acids in chickens found that when fully supplied in the form of small peptides to animals, not fertilization effects of tryptophan absorption rate of lysine. Small peptides is conducive to mineral absorption is due to small peptides and Ca, Fe, Cu, Zn, and other metals in the form of chelates with, through the small intestine brush border, in the form of small peptide promoting the transfer and absorption of these metals.

1.2 functionality also has a lot of small peptides physiological activities, such as antimicrobial activity, antioxidant, immune effects, antihypertensive and cholesterol-lowering effects, these types of realization and the biological activity of peptides, source had a strong link.
