Structure

Thus proteoglycan aggregates composed of coiled turns, forming a sieve-like microporous structure, called molecular sieves. Zeolite molecular sieve allowing only its micro-pores is less than the material molecular sieve separation through its pores large macromolecules, the bacteria has a barrier function. The matrix becomes the limiting diffusion of bacteria and other harmful substances defensive barrier. Hemolytic streptococcus and cancer cells can produce hyaluronidase, decomposition proteoglycan matrix structure damage, to be spread. The proteoglycan aggregates molecular sieve adsorbent further combined with a plurality of hydrophilic groups capable of binding to a large number of water molecules, forming extracellular "reservoirs."
