hyaluronic acid

 [hi″ah-loo͡-ron´ik]
a glycosamino-glycan found in lubricating proteoglycans of synovial fluid, vitreous humor, cartilage, blood vessels, skin, and the umbilical cord.

hy·a·lu·ron·ic ac·id

(hī'ă-lū-ron'ik as'id),
A mucopolysaccharide consisting of alternating β1,4-linked residues of hyalobiuronic acid, forming a gelatinous material in the tissue spaces and acting as a lubricant and shock absorbant generally throughout the body; it is hydrolyzed to disaccharide or tetrasaccharide units by hyaluronidase.

hyaluronic acid

/hy·al·uron·ic ac·id/ (hi″ah-ldbobr-ron´ik) a glycosaminoglycan found in lubricating proteoglycans of synovial fluid, vitreous humor, cartilage, blood vessels, skin, and the umbilical cord. It is a linear chain of about 2500 repeating disaccharide units.

hyaluronic acid

(hī′ə-lo͝o-rŏn′ĭk)
n.
A glycosaminoglycan that is found in extracellular tissue space, the synovial fluid of joints, and the vitreous humor of the eyes and acts as a binding, lubricating, and protective agent.

hyaluronic acid

[hī′əlyoo͡ron′ik]
a mucopolysaccharide formed by the polymerization of acetylglucosamine and glucuronic acid, which occurs in vitreous humor, synovial fluids, and various tissues. Known as the cement substance of tissues, it forms a gel in intercellular spaces.

hy·a·lu·ron·ic ac·id

(hī'ă-lūr-on'ik as'id)
A mucopolysaccharide forming a gelatinous material in the tissue spaces and acting as a lubricant and shock absorbant; hydrolyzed by hyaluronidase.

hyaluronic acid

Hyaluronate, a long polymer glycosaminoglycan, consisting of repeating disaccharide units, found in basement membranes, mature oocytes, skin, cartilage, the vitreous body of the eye and the synovial fluid of joints.

hyaluronic acid

glycosaminoglycan promoting cell proliferation (including fibroblasts)

hy·a·lu·ron·ic ac·id

(hī'ă-lūr-on'ik as'id)
A mucopolysaccharide forming a gelatinous material in the tissue spaces and acting as a lubricant and shock absorbant.

hyaluronic acid (hī´əlŏŏron´ik),

n a mucopolysaccharide that forms the gelatinous substance in the tissue spaces. Hyaluronic acid is the intercellular cementing substance found throughout the tissues of the body.

hyaluronic acid

a sulfate-free mucopolysaccharide in the intercellular substance of various tissues, especially the skin; also isolated from the vitreous humor, synovial fluid, umbilical cord, etc. Used therapeutically in degenerative joint disease and in solution as a tear film replacement.
