Trying to discover more effective functions of bioactive peptides is a priority, as long as mastering the corresponding technologies, such as bio-extraction, artificial synthesis, microbial fermentation, genetic engineering, ghrh hormone, and so on. Scientists have focused on a wide range of fields in peptides research from many aspects, for example, development and production. In terms of food, additives, pharmaceutical research or diagnostic reagents, peptides could embrace a broader development prospect in the future.
The so-called peptides, whose molecular structure is between amino acids and proteins, are known as a class of compounds. Most people are familiar with insulin, which is actually a polypeptide. In fact, such peptide is made up of amino acids. Generally, there are hundreds of peptides in human body. Active peptide, also known as functional peptide and oligopeptid, mainly refers to the polypeptide containing 2-10 amino acids, with molecular weight under 2000D. It is a kind of active substance and functional factor that has important physiological functions.
Polypeptide is a kind of active peptide and its small molecule peptide content is above 88%. Biologically active peptide is a specific protein that has important physiological functions while protein generally doesn’t possess such feature. Polypeptide contains large amounts of functional factors that are beneficial to human health, so intaking polypeptide can improve people’s health level.
In recent years, research in peptides has made a rapid progress. Research shows peptide substances, in addition to a general effect of protein nutrition in bremelanotide, also plays an important and irreplaceable regulating role in human body, which involves almost all the body’s physiological activities, such as nerves, digestion, absorption, metabolism, circulation, growth, reproductive and endocrine.
Effects of Small Peptides on the Human Body:
Inhibit of cell degeneration and enhance human immunity
Activate cell activity and effectively remove harmful free radicals
Repair degeneration of human cells and improve cell metabolism
Promote and maintain normal cell metabolism
Specific Role of Peptides on the Human Body:
1. Provide a variety of amino acids that help the body to produce new tissue replacement necrotic tissue
2. Provide a new organizational structure for amino acids
3. Deliver oxygen and nutrients to the cells through the identification of blood
4. Regulate the body’s water and electrolyte balance
5. Generate antibodies against bacteria and infections under immune system and then improve its immune functions
6. Promote wound healing and wound blood coagulation
7. Produce enzymes to help convert food into energy
8. Repair cells, improve cell metabolism, prevent cell degeneration, and play an anti-cancer role
9. Promote regulatory proteins and enzymes
10. Improve communication of vital chemical messenger information between cells and organs
11. Eliminate cardiovascular and cerebrovascular diseases
12. Improve the endocrine and nervous system
13. Improve the digestive system and chronic intestinal diseases
14. Promote hematopoietic function and anemia, prevent platelet aggregation, and improve the oxygen-carrying capacity of red blood cells
15. Eliminate excess free radicals
16. Improve significant effects in rheumatism, arthritis, diabetes, and other diseases
To be more specific, with custom peptide synthesis, some nutritionists have noted that functional food is emphasizing its components on the human body, which can fully display the body’s defense function. Certainly, other functions like regulating circadian rhythms, disease prevention and the promotion of rehabilitation are also presented in industrialized food, too. As can be seen, peptide is a rare health food and its long-term use can be beneficial to enable improve people’s overall nutrition level.

Editor: Ronald E. Reid
Furthering efforts to simulate the potency and specificity exhibited by peptides and proteins in healthy cells, this remarkable reference supplies pharmaceutical scientists with a wealth of techniques for tapping the enormous therapeutic potential of these molecules-providing a solid basis of knowledge for new drug design.
4. HPLC of Peptides and Proteins: Methods and Protocols
Editor: Marie-Isabel Aguilar
The introduction of high-performance liquid chromatography (HPLC) to the analysis of peptides and proteins some 25 years ago revolutionized the biological sciences by enabling the rapid and sensitive analysis of peptide and protein structure through the exquisite speed, sensitivity, and resolution that can be easily obtained.
5. Peptide Synthesis Protocols
Editor: Michael W. Pennington, Ben M. Dunn
Peptide synthesis has emerged as one of the most powerful tools in biochemical, pharmacological, immunological, and so on.
6. Peptide Hybrid Polymers
Editor: Harm-Anton Klok, Helmut Schlaad
The construction of well-defined hybrid materials consisting of synthetic polymers and (poly)peptides or proteins has attracted much attention in recent years.
7. Antibacterial Peptide Protocols (Methods in Molecular Biology)
Editor: William Schaffer
The topic of this volume of Methods in Molecular Biology, the diverse methods used in research on antibacterial peptides, is thus quite timely. It is essential that reliable techniques and strategies be made available not only to those of us in the field, but also to the newcomers and researchers in complementary disciplines.
8. Peptide and Protein Design for Biopharmaceutical Applications
Editor: Knud Jensen
Peptides serve as effective drugs in the clinic today. However the inherent drawbacks of peptide structures can limit their efficacy as drugs. To overcome this researchers are developing new methods to create ‘tailor-made’ peptides and proteins with improved pharmacological properties.
9. Cell-Penetrating Peptides Methods and Protocols
Editor: GY Wiederschain
The classical view on how peptides enter cells has been changed due to the development in the research field of cell-penetrating peptides (CPPs).
