Hyaluronic acid is a naturally occurring glycosaminoglycan.
It is a constituent of the intercellular matrix of connective tissue that exists in almost all vertebrates. HA is found at high concentrations in the umbilical cord, in the aqueous and vitreous humor of the eye, in synovial fluid in joints, in group A and C hemolytic streptococci , and in rooster combs. It plays an important role in a number of physiological functions, including protection and lubrication of cells, maintenance of the structural integrity of tissues, transport of molecules and cells, and fluid retention and regulation. The molecular structure of hyaluronic acid is shown below.
