Hyaluronan is synthesized by a class of integral membrane proteins called hyaluronan synthases, of which there are three types in vertebrates: HAS1, HAS2, and HAS3. These enzymes prolong hyaluronic acid by repeatedly adding D-glucuronic acid and N-acetyl-D-glucosamine to nascent polysaccharides as i

Cell migrationCell migration is critical for the formation of granulation tissue. [20] The early stages of granulation tissue are dominated by HA-rich extracellular matrix, which is thought to be a favorable environment for cell migration into this temporary wound matrix. [20] HA provides an open h

Hyaluronic acid (/ˌhaɪ.əljʊəˈrɒnɪk/;[2][3] abbreviated as HA; conjugated group hyaluronate), also known as hyaluronic acid, is an anionic, nonsulfated glycosaminoglycan, widely Distributed in connective tissue, epithelial tissue and nervous tissue. It is unique among glycosaminoglycans in that it is

The skin is the organ with the largest surface area of the human body, and it bears various external pressures daily, such as environmental pollution, UV damage, oxidative stress,etc.As the metabolism rate decreases, all kinds of "cell garbage" accumulate unknowingly.At this time, autophagy comes in
