For "hyaluronic acid", you may know only the tip of the iceberg.
An Irreplaceable natural substance in the human body
"Hyaluronic acid, which is hyaluronic acid, is actually a natural component in the human body. It is a natural linear polysaccharide present in human and animal tissues. It is mainly distributed in the vitreous, joint, umbilical cord, skin and other parts of the human body. To play important physiological functions.
Hyaluronic acid is an irreplaceable natural substance in the human body. It is high in the body during embryonic period, and its body content decreases with age. If the relative content of hyaluronic acid in the human body at the age of 20 is 100%, it will decrease to 65%, 45%, 25% at 30, 50, and 60 years old, skin aging, joint deterioration, arteriosclerosis, and old eyes. The symptoms are closely related to the gradual decrease in hyaluronic acid content in the body. The amount of hyaluronic acid contained in the same age group is also different, and the content of the body of the premature aging is significantly reduced, showing many symptoms of aging.
Hyaluronic acid was first discovered in 1934 by Meyer, a professor of ophthalmology at Columbia University in the United States, who first isolated hyaluronic acid from the vitreous vitreous and analyzed its structure. In addition to the bull's eye, the highest content of hyaluronic acid in nature is the cockscomb and the human baby's umbilical cord. In the 1970s, people began to extract hyaluronic acid from the cockscomb. However, the hyaluronic acid extracted from animal tissues has a good effect, but the extraction rate is extremely low, the separation process is complicated, and the yield is limited, which also makes the hyaluronic acid expensive. , up to $5,000 / kg.
In the 1990s, the domestic research on the fermentation technology of hyaluronic ac
