The smaller the molecular weight of collagen, the easier it is absorbed. This is a well-known common sense. But some businesses claim that too small a molecular weight becomes an amino acid. Experts point out that this is pure nonsense. As long as it is collagen, the smaller the molecular weight, the easier it will be absorbed. Because when the molecular weight is less than 1000 Daltons, it is still collagen instead of ordinary amino acids that some people advocate.
Experts say that all kinds of organisms, from the simplest virus to humans, are composed of the same 20 kinds of amino acids. These more than 20 kinds of amino acids make up the protein world in various ways. One amino acid is connected to another amino acid by a peptide bond, and the compound formed is called a peptide. Peptides containing less than 10 amino acids are called oligopeptides, and those with more than 10 amino acids are called polypeptides. The di- and tripeptides in oligopeptides (also known as oligopeptides) are often referred to as small peptides. This is the smallest molecular weight carrier on the market and it is the easiest to be fully absorbed.
And collagen supplementation is actually supplementing collagen fragments (ie collagen peptides, or collagen peptides)! The body's absorption rate of collagen is only 1%! Generally, the molecular weight of collagen is about 300,000 Daltons, and the molecular weight of collagen peptides is 2,000 to 10,000 Daltons, and the molecular weight of less than 1,000 Daltons is the collagen oligopeptide (not 2000 to 3,000 Daltons).
In fact, there are many ways to supplement collagen, including diet. But why do you still need to drink collagen products? This is mainly because the molecular weight of collagen in food supplements is too large, and the human body absorbs too little. Similarly, many collagen products on the market have large molecular weights and are not conducive to absorption. Of course, some unscrupulous merchants will create a concept and say that the collagen with a large molecular weight is a product with a small molecular weight. At present, there are not many collagen products on the market with a molecular weight of less than 1,000 Daltons. Only marine collagen peptides developed by the China Food Fermentation Industry Research Institute and sold by Shangou Bar are available.
Some people advocate that the molecular weight of collagen is too small, then it becomes an ordinary amino acid, not the role of collagen. This is totally nonsense. Imagine, if so, why the academic session still called collagen oligopeptides, rather than amino acids, with molecular weights less than 1000 Daltons. Obviously, this statement does not hold. The smaller the molecular weight of collagen, the more easily it is absorbed. Businesses are so advocating because the level cannot be reached and small molecule collagen cannot be achieved.
In recent years, collagen has rapidly become popular. Under the banner of collagen, major brands have developed various collagen beauty drinks and collagen skin care products. Everyone knows that crazy supplementation is not enough, but collagen is actually yellow and dull The culprit.
This is definitely not alarmist. Collagen will become collagen egg yolk with age and saccharification, which will make the skin yellow and age.
From the age of 18, the body's collagen loss, year after year, to less than 40% at the age of 40, whether you eat VC every day, eat fruit, you can only make up less than 1/4. Aging approaches you step by step! Youth is gone! Therefore, supplementing collagen has become an indispensable thing for everyone, especially for female friends. But there are many types of collagen in the market, how to choose?
Experts suggest that you must choose carefully and not be fooled by the propaganda of the business. When choosing collagen, be sure to choose a product with a small molecular weight.
