The Efficacy Of Collagen Peptides
Jul 27, 2022
Collagen can be subdivided into: macromolecular collagen and small molecular collagen peptides. Usually we eat the jelly of pig’s trotters, which contains collagen (amylase), but it is a macromolecular protein with a molecular weight of 300,000 Daltons. The above can not be directly absorbed by the human body and the absorption rate is very low; and the collagen whose molecular weight is controlled within 6000 Daltons through acid-base, enzyme digestion and other technologies is called collagen peptide. Peptide is between amino acids and macromolecules. In the substance between proteins, two or more amino acids are dehydrated and condensed to form several peptide bonds to form a peptide, and multiple peptides undergo multi-level folding to form a protein molecule. Peptides are precise protein fragments, and their molecules are only nanometer-sized. They are easily absorbed by the stomach, blood vessels, and skin, and their absorption rate is much higher than that of macromolecular proteins.
1. Antioxidant
Free radicals are associated with human aging and many diseases, and the development of antioxidants has received much attention. The collagen peptide solution decomposed by collagenase has antioxidant properties, which can reduce free radicals in the body and inhibit diseases and aging. Studies have shown that protein peptides have good scavenging effects on superoxide anion free radicals, DPPH free radicals and hydroxyl free radicals.
2. Whitening skin care
Collagen peptides have good moisturizing, water-locking, whitening and other effects, so they are widely used in the field of cosmetics. Some scholars have studied the acid leaching-water extraction method to extract salmon gelatin, and obtained protein peptides by enzymatic hydrolysis. Moisturizing, has a certain whitening effect.
3. Protect the liver and stomach
Collagen peptides can repair the gastric mucosa and liver. The inhibition of TNF-α by collagen peptides can reduce the apoptosis of hepatocytes and the release of free radicals and lysosomal enzymes of oxygen by leukocytes, thereby protecting the liver. Collagen peptides can reduce the incidence of bleeding and ulcers in the gastric mucosa.
