In recent years, peptide has become a hot word related to human health.
Almost all cells in our body are regulated by peptides, which involve hormones, nerves, cell growth and reproduction. Scientists have confirmed that the occurrence, development, treatment and rehabilitation of all diseases are related to peptides.
So, what is a peptide? As we all know, protein is one of the most important organic substances in cell structure. Protein is the main substance that constitutes the miracle of human tissues and plays an important role in human life activities. It can be said that protein is the material basis of life. Without protein, there would be no life.
Amino acids are the basic components of protein. All living things, from the simplest virus to the most advanced human beings, ever-changing creatures are protein composed of exactly the same 20 amino acids. Protein is a polymer compound formed by combining α -amino acids in a certain order to form polypeptide chains, and then combining one or more polypeptide chains in a specific way.
Modern biology discovered an intermediate substance different from protein when studying protein. This biochemical substance between amino acid and protein is called peptide. The molecular weight of peptide is smaller than that of protein and larger than that of amino acid, which is a fragment of protein. Peptides are compounds formed by two or more α -amino acids linked together by peptide bonds.
As the saying goes, people over the age of 30 consume half of their qi and blood, and people over the age of 50 are riddled with diseases. Hypertension, heart disease, diabetes, coronary heart disease, stomach disease and other diseases have become common diseases and high incidence around us. According to the statistics of the health department, middle-aged and elderly patients over 40 years old have at least three diseases. This is a typical one-in-one disease.
According to the report of the World Health Organization, 65,438+0/3 elderly people died not from natural causes, but from improper medication. According to statistics, the probability of adverse reactions of a person taking three drugs at the same time is 50%, and the probability of adverse reactions of taking more than five drugs at the same time is 100%. People who take several or even a dozen drugs at the same time every day often hurt the spleen and stomach first, and then the liver and kidney. In particular, physical and chemical changes will occur between various drugs, and drugs will contradict each other and "fight" with each other, resulting in reduced efficacy and increased side effects. Finally, drug poisoning will lead to the failure of the main organs of the human body, which is simply worse for the already weak elderly patients.
How can I not get sick or get sick less? How can we spend a healthy and relaxed old age? Who's in control of all this? Who controls cells and genes? Who is protecting our health?
1984, when Dr. Melifeld studied human cells, he found that a special substance in cells participated in the growth and development of human body. It controls the quantity, quality and speed of protein synthesis and protein synthesis, and controls the normal expression and replication of genes, thus controlling human diseases and aging. Dr Melifeld named this substance as an active polypeptide and won the Nobel Prize in Medicine that year.
Professor Gong Yueting, a biochemist of China Academy of Sciences, said: The causes of hypertension, gastrointestinal diseases, diabetes, neuropathy, cancer, low immunity, abnormal sexual development and performance, osteoporosis, deformity and other diseases are directly related to active peptides. Therefore, peptides have become the focus of research all over the world, and the study of active peptides has promoted the application of peptides by human beings.
SARS, a plague that occurred in China in 2003, made everyone familiar with peptides, and therefore let everyone know that peptides can improve immunity. Biopeptide is a kind of protein and amino acid substance quickly absorbed by human body, and its appearance is a major change in the history of human nutrition. Xanthoceras sorbifolia Bunge peptide is the highest content of all plant protein transformants at present, which has advantages, functionality, broad development prospects and huge market potential.
Xanthoceras sorbifolia Bge is a deciduous tree or shrub of Xanthoceras of Sapindaceae, also known as Xanthoceras sorbifolia, longevity fruit, Fairy Fruit, Papaya, Chaenomeles, Monk Deng Mao Road, etc. It is a unique ancient species left over from the prosperous tertiary of angiosperms (about 65 million years ago). Xanthoceras sorbifolia Bunge has a life span of 2000 years, strong adaptability and strong stress resistance (cold resistance, drought resistance and salt and alkali tolerance). Xanthoceras sorbifolia Bunge is a kind of treasure, which has high edible value, medicinal value, ornamental value and ecological value. It is a treasure of trees and China, and a wonderful garden.

It has the functions of lowering cholesterol, softening blood vessels and lowering cholesterol and blood lipid. Xanthoceras sorbifolia Bunge oil is rich in neurogenic acid (2.6%~5%), which is the main element for the health of heart, brain and nervous system. Xanthoceras sorbifolia Bunge tea has antibacterial, anti-inflammatory, hemostatic, diuretic, digestion promoting, lipid-lowering, antioxidant, and anti-aging effects, and can be used for treating insomnia, gout, gastroenteritis, prostatitis, "lowering three highs" and losing weight. Vigorously developing Xanthoceras sorbifolia Bunge industry can solve the ecological crisis and edible oil crisis and promote the harmonious and healthy development of ecological, economic and social benefits.
Xanthoceras sorbifolia Bunge kernel is rich in nutrition, containing 19 amino acids, various trace elements and vitamins, and the crude protein is over 62%. It is of great significance to develop Xanthoceras sorbifolia Bunge polypeptide.
Xanthoceras sorbifolia Bunge can be made into Xanthoceras sorbifolia Bunge peptide nutrition, which contains 1 ~ 80% peptides that can be directly absorbed by human body, as well as linoleic acid, linolenic acid, oleic acid, saponin, VB, W, VE, Busu, calcium, zinc, iron, potassium, magnesium and glucose.
Xanthoceras sorbifolia Bunge-oil cake after oil pressing. Its protein content reaches 69.7%, which is one of the highest in the plant world at present. It contains 18 kinds of amino acids, including essential amino acids, but it is impossible to synthesize 8 kinds of amino acids by itself. The Xanthoceras sorbifolia Bunge peptide processed by this oil cake accounts for 65% of the small peptides below 1000 units, and it is a very high-quality small molecular peptide. It is the best choice for people who are weak, recovering from a serious illness, exhausted physically and mentally, have poor appetite and have difficulty eating.
Hypertension is a global public health problem, which can induce many chronic diseases, such as stroke, myocardial infarction and coronary heart disease. Angiotensin converting enzyme (ACE) is a zinc-containing dipeptide carboxypeptidase, which plays an important role in regulating human blood pressure. ACE inhibitory peptide, commonly known as antihypertensive peptide, is a kind of polypeptide with antihypertensive activity isolated from food-borne protein, which generally contains only 2 ~ 20 amino acid residues and can quickly enter the blood circulation through digestive mucosa. ACE inhibitory peptides can competitively bind to two active functional regions of ACE, inhibit ACE activity, and inhibit the transformation from angiotensin I to angiotensin II, thus playing a role in lowering blood pressure. The antihypertensive peptide extracted from protein has become the focus of domestic and foreign scholars because of its high food safety. Peptides were prepared by enzymatic hydrolysis of Xanthoceras sorbifolia Bunge. The recovery rate of peptides less than 5 kDa was 75%. Among them, the peptide less than 1 kDa has high antihypertensive activity in vitro, and the ACE inhibition rate is 83. 43% and IC50 are 0. 394 mg/ml. ACE inhibitory peptides can be further isolated and purified, and the structure of peptides can be systematically characterized by various spectral techniques. The results showed that the hydrolyzed peptide of Xanthoceras sorbifolia Bunge had significant anti-ACE activity in vitro, and it could be used as a raw material for the development of antihypertensive peptides.
At present, extracting peptides from Xanthoceras sorbifolia Bunge kernel protein is a research hotspot in recent years. The preparation methods of Xanthoceras sorbifolia Bunge peptide include enzymatic hydrolysis, chemical method and fermentation method.
