Hyaluronic acid is a naturally occurring polysaccharide, a glycosaminoglycan that is a component of the "ground substance" or extracellular matrix of the dermis (Lupton and Alster 2000).
Whereas its cousins take mere minutes or hours to decay, only half of the carbon-14 component of a given substance is gone after 5730 years, having become nitrogen-14.
Both vitamin D and a component of bile called lithocholic acid (LCA)—a substance implicated in colorectal cancer that is produced during the breakdown of fats in the digestive tract bind to the same cellular receptor.
The published reports used as safety evidence for three of the four chemicals evaluated not the specific chemical at hand, but a component of it or a structurally related substance.
This protein contributes to formation of large bacterial cell aggregates through binding to enterococcal binding substance (EBS), a component of which appears to include lipoteichoic acid [8].
Our findings have significant clinical implications: Craving is a central component of both substance and behavioral addictions [ 57– 59], and is an important potential therapeutic target.
Consider the recent revelations of the addition of toxic substances, including a component of some antifreezes and methanol, or wood alcohol, to Austrian and Italian wines, and the blending of the tainted wines with other wines.
α-Tubulin is a component of microtubules, which are involved in reabsorption of substances in kidney tubules via the transport of vesicles from the luminal surface to the basal surface of the tubules.
Beta thalassemia, like its better-known cousin sickle-cell disease, is caused by a congenital defect in the globin protein, a key component of hemoglobin, the substance that allows our red blood cells to carry oxygen.
Containing viscoelastic resin, soluble proteins, glucose, free amino acids, and electrolytes, vitreous is a major component of the refractive substance in the eye.
We have designed a device that separates components of a chemical substance by mass and detects them simultaneously, thus addressing the problem that was proposed by the industrial partner.
