With the increasing popularity of small molecule peptides, more and more people have just begun to accept and consume small molecule peptides. In fact, many people have very little grasp of peptides. So, what is the effect of taking peptides on the absorption of nutrients? Let’s take a look with everyone below!
Peptides-basic nutrients for cells
Food-derived peptides are new-type proteolytic products made from protein taken as raw materials through enzymatic hydrolysis, separation, and purification. Food-derived peptides come from common sources. According to the different sources of protein raw materials, they can be divided into small animal-derived protein peptides and green plant-derived protein peptides. Food-derived peptides are different in terms of relative molecular mass, and are divided into food-derived oligopeptides (molecular weight less than 1000Da) and food-derived peptides (molecular weight greater than 1000Da).
In the past two decades, researchers from all over the world have done a lot of work on the product development level of food-derived peptides. They have isolated and assessed peptides with various biological activities, such as antioxidants, from different food protein enzymatic substances. Peptides, antihypertensive peptides, antithrombotic peptides, lipid-lowering peptides, opioid peptides, immunomodulatory peptides, antibacterial peptides, etc. Food-derived peptides have a high safety factor, have a universal physiological regulation effect, and are a promising factor. They have become a hot spot in the nutrition and health industry in the world.
Many studies have shown that food-derived peptides have a variety of nutritional and health effects. Some active peptides are present in the amino acid sequence of the protein in terms of their activity, but after enzymatic hydrolysis in or outside the body (such as in the digestive tract and the processing of food materials), this peptide is released. Therefore, they may have a variety of physiological activities. In addition, although the active peptide has a small amount of components in the body, its physiological activity is indeed very obvious.
(1) Peptides promote amino acid absorption and protein synthesis
Among the food-derived peptides, the oligopeptide (generally composed of 2-6 amino acids) shipping system has the characteristics of faster speed, low energy consumption, and is not easily saturated, and it is absorbed faster than relatively dispersed amino acids. Because oligopeptides and dispersed amino acids have an unrelated absorption system, the two interfere with each other, so it helps to alleviate the absorption inhibition caused by the competition of dispersed amino acids with each other's absorption domains, thereby promoting the absorption of peptide-form amino acids and high synthesis of proteins. Efficiency also rises.
For example, when lysine and arginine exist in a dispersed form, they will compete with each other for the absorption domain, and when lysine and arginine exist in a peptide form, arginine is not harmful to its absorption. In addition, oligopeptides in the circulatory system can also directly participate in the synthesis of institutional proteins. Studies have shown that when peptides are used as the nitrogen source, the overall protein accumulation is higher than the relative amino acid diet or detailed protein diet.
(2) Peptides promote the absorption of mineral elements
Many studies have reported that food-derived peptides have the effect of promoting the absorption and utilization of mineral elements. Food-derived peptides can generate chelate with chemical elements to improve water solubility, thereby promoting the absorption of mineral elements. For example, the phosphorylated serine residue contained in the hydrolyzed casein phosphopeptide can bind to Ca2+ and Fe2+, thereby improving its solubility.
