Peptide (tai) is a biological molecule composed of amino acids linked together by peptide bonds, and it is a substance that lies between amino acids and proteins. Peptides participate in various important physiological processes in the body and have multiple functions such as regulating immunity, antioxidation, and promoting collagen synthesis.
Definition:
Category:
Based on the number of amino acids, peptides can be classified into dipeptides, tripeptides, tetrapeptides, etc. Peptides composed of three or more amino acids are called polypeptides. Polypeptides with a molecular weight greater than 10,000 daltons are usually referred to as proteins.
Peptides play various important physiological roles in the body, such as:
Immune regulation: Certain peptides can enhance the function of the immune system and help fight diseases.
Antioxidation: Certain peptides have antioxidant properties, which can eliminate free radicals and protect cells from oxidative damage.
Promotion of collagen synthesis: Certain peptides can stimulate the synthesis of collagen, which is helpful for maintaining skin elasticity and joint health.
Regulation of blood sugar: Some studies have shown that specific peptides may help regulate blood sugar levels.
Improvement of sleep: Some peptides participate in the regulation of the sleep cycle and may help improve sleep quality.
Promotion of intestinal health: Some peptides can promote the growth of beneficial bacteria in the intestines and improve the balance of intestinal flora.
Neuroprotective effect: Some research shows that certain peptides may have neuroprotective effects, helping to protect nerve cells from damage.
Applications:
Peptides have wide applications in the fields of medicine, health supplements, and cosmetics.
Medicine: Peptide-based drugs have potential in treating various diseases, for example, peptide-based hormones play an important role in endocrine therapy.
Health supplements: Peptides as a dietary supplement can replenish the deficiency of peptides in the body and enhance physical health.
Cosmetics: Some peptides have anti-aging, moisturizing, whitening and other effects, and are widely used in skin care products.
