What is a Peptide?

Peptides, an organic compound, are formed by the combination of two or more amino acids through the amino group of one amino acid and the carboxyl group of another amino acid. A compound where two amino acids are connected by peptide bonds is called a dipeptide, and a compound where three amino acids are connected by peptide bonds is called a tripeptide.

Peptides are Composed of Amino acids

An amino acid is called an amino acid, and when there are more than 51 amino acids, it forms a protein. And 2-10 amino acids are called small molecule peptides, which can enter the bloodstream within 5 minutes and cells within 10 minutes. Compared to proteins, the human body absorbs small molecule peptides more easily.

Molecular Weight of Peptides

Peptides can only be called peptides if their molecules are nano-sized and have a molecular weight range of 5000 to 180. A peptide with a molecular weight range of 5000 to 10000 is called a large peptide. Peptides with molecular weights between 1000 and 180 are called small peptides, oligopeptides, oligopeptides, and also known as small molecule active peptides. Biologists refer to peptides as "amino acid chains" and collectively refer to small molecule active peptides as "biologically active peptides".

Classification of Peptides

There are many types of peptides, which can be roughly divided into three categories:

Animal peptides: including collagen peptides, thymic peptides, etc

Plant peptides: including soy peptides, walnut peptides, etc. (these peptides generally have a relatively large molecular weight)

Chemically synthesized peptides and drugs: including oxytocin, gastrin tetrapeptide, etc

Effect of "peptide" on Human Body

Peptides play an important role in the human body and can be divided into antioxidant peptides and cholesterol peptides. Peptide elements can serve as transportation tools in the human body, delivering all nutrients and various trace elements to the cells and organ tissues of the human body. They are also important physiological regulatory substances that are easily digested and absorbed by the human body.

1. Promote muscle cell synthesis: Peptides are proteins that can promote muscle cell synthesis, increase the content of muscle tissue in the body, and enhance exercise ability and strength.

2. Promote liver cell regeneration: Peptides have a small molecular weight, are easy to digest and absorb, and can provide comprehensive nutritional support for the repair and regeneration of damaged liver cells. Peptides can directly penetrate into damaged liver cells, stimulate the synthesis of liver cell DNA, promote liver cell regeneration, and thus help restore liver function.

3. Anti lipid peroxidation: Small molecule peptides have anti lipid peroxidation and free radical scavenging effects, which can protect liver cells, mitochondrial membranes, and endoplasmic reticulum from damage caused by alcohol or other chemicals.

4. Regulating immune function: Peptides provide protein nutrition to the human body, which can regulate the body's immune function, increase the body's immune barrier, and improve the body's immune capacity.

5. Regulating cholesterol and fat metabolism: Peptides can improve the function and vitality of liver cells, promote fat metabolism, and eliminate perihepatic fat. Certain peptides can also regulate cholesterol metabolism, regulate hormone and endocrine levels in the human body, and maintain environmental balance in the body.

6. Protecting cardiovascular and cerebrovascular systems: Peptides can enhance the compressive strength of capillaries, continuously eliminate venous thrombosis, and ensure smooth blood flow in blood vessels; The effect of significantly reducing cholesterol and triglycerides, promoting their metabolism and dissolution, and eliminating low-density proteins; To provide services and guarantees for the physical and mental health of cardiovascular and cerebrovascular systems.

Information About Research Grade Peptides:

Searching for invention patents, it was found that there are 49292 studies on bioactive peptides in China, 11515 in the United States, 4473 in Japan, and 950 in the United Kingdom. The number of invention patents in China is five times that of the United States, with the main areas focused on anti-cancer, immunity, beauty, anti-aging, and so on.

At present, global peptide products are growing at a rate of 20% annually. Domestic and international research on active peptides mainly focuses on three areas: medicine, food, and feed (animal food). The main directions include anti infective, immune and immunosuppressive peptides and their derivatives, peptide growth factors, cardiovascular, anti-tumor and anticancer peptides, food peptides, etc.

Antiinfective peptides - including antimicrobial peptides, antiviral peptides, antimicrobial antiviral peptides, etc. - can inhibit or kill pathogenic microorganisms. There are broad prospects in the fields of medicine, food preservation, and alternative antibiotics for feed.

Immune peptides - exert immune regulatory effects. Like thymopentin (TP-5), which has been artificially synthesized; For example, cell wall acyl dipeptide (MDP) can enhance cellular immune response, activate macrophages and L-helper cells. Mainly used for various diseases such as immune deficiency and anti-cancer.

Immunosuppressive peptides and their derivatives - currently used to prevent transplant rejection and treat autoimmune diseases, the most representative of which is cyclosporin A (CSA).

Peptide growth factor - can strongly promote cell growth and has regulatory effects on cell differentiation, growth, proliferation, and function. Such as epidermal growth factor (EGF), insulin-like growth factor (IGG-I), interleukin-converting growth factor (TGF-1), nerve growth factor (NGF), etc. Among them, epidermal growth factor (EGF) has been widely used in fields such as skin diseases, beauty, and skincare.

Cardiovascular active peptides, such as antihypertensive peptides and atrial fibrillation peptides containing angiotensin converting enzyme (ACE), include atrial natriuretic peptide, B-type natriuretic peptide, endothelial vasoconstrictor peptide, relaxin, mediators, etc.

Antitumor and anticancer peptides - More than 100 types of antimicrobial peptides have been found to have anticancer activity. Such as bee venom peptide, RGD (containing arginine aspartate) peptide, polyerga (spleen extracted peptide, anti radiation and chemotherapy), and anti-cancer active peptide.

Peptide vaccines, diagnostic peptides, etc. - Peptide vaccines are vaccines prepared through chemical synthesis techniques based on the amino acid sequence of a known or predicted antigenic epitope in the pathogen antigen gene.

Peptide vaccines have the characteristics of safety, easy preparation, strong specificity, and easy preservation and application. It overcomes many drawbacks of traditional vaccines, can be chemically synthesized on a large scale, is easy to purify, and is very safe for human application.

Antioxidant peptides: eliminate superoxide radicals, hydroxyl radicals, alkane radicals, etc. Such as glutathione, antioxidant peptides derived from soy protein, antioxidant peptides derived from corn protein, antioxidant peptides derived from wheat protein, antioxidant peptides derived from rice bran protein, antioxidant peptides derived from dairy products, and antioxidant peptides derived from marine organisms.

Blood pressure lowering peptides: angiotensin converting enzyme (ACE), soy peptides, corn protein peptides, etc.

Lipid lowering and cholesterol lowering peptides: ginseng peptides, jellyfish peptides, soy peptides, etc.

Immunomodulatory peptides (abbreviated as immune peptides): thymic peptides, spleen peptides, sheep fetal disc peptides, etc.
