water

 [waht´er]
1. a clear, colorless, odorless, tasteless liquid, H2O.
2. an aqueous solution of a medicinal substance; called also aromatic water.
bound water water in the tissues of the body bound to macromolecules or organelles.
distilled water water that has been purified by distillation.
free water that portion of the water in body tissues which is not bound by macromolecules or organelles.
water for injection water for parenteral use, prepared by distillation or reverse osmosis and meeting certain standards for sterility and clarity; it may be specified as sterile if it has been sterilized and as bacteriostatic if suitable antimicrobial agents have been added.
purified water water obtained by either distillation or deionization; used when mineral-free water is required.

bound wa·ter

water held to colloids and other substances and not removed by simple filtration.

bound water

water in the tissue of the body bound to macromolecules or organelles.

bound water

Intracellular water attached to organic molecules. It is not available for metabolic processes.

Our study also indicated that evergreen woody plants of Sabina can increase freezing tolerance by decreasing free water and increasing bound water during cold acclimation.
The critical water content has been interpreted as the transition from the predominance of bound water with a low dielectric permittivity ([[epsilon].
They have a sigmoidal shape with three regions reflective of three types of water that depend on the chemical composition of the sorption sites: (i) water very strongly associated with ionic groups of macromolecules, (ii) water weakly bound to polar non-ionic groups, and (iii) very weakly bound water that interacts with the hydrophobic groups.
Residing in the cell wall, bound water affects wood's bulk.
Because of the dehydration reaction of free water and weakly bound water, a large endothermic valley will appear at 25~250[degrees]C.
22] of the water component gradually moves to the right and becomes bigger and bigger, indicating that the bound water molecules are the least mobile owing to their direct attachment to the chain segments via electrostatic interactions, and the additional water could enhance the mobility of water molecules.
Among their findings was that three endothermic physiochemical transformations occur during heating: release of moisture between room temperature and 212F (100C), burnout of organic compounds between 572-932F (300-500C), and release of chemically bound water in the range of 932-1652F (500-900C).
Walters found that two big influences on deterioration are the nature of water binding within seeds and the effect of the bound water on seed cells.
Unlike powdered fat replacers, this product is pre-hydrated and gelled to convert the free water to bound water.
ClusterWater enhances the biological effectiveness of active molecules, because the bound water clusters are structurally stabilizing factors and play a role in energy transduction and amplification, even at extreme dilutions, which increases testing sensitivity.
As the temperature decreases, evidently, the vapor pressure in air decreases faster than that of bound water in wood, thereby causing the water to migrate from the cell wall to the air (in the lumina).
