Protein crystals commonly have as much as 50% water content. Molecules are also labeled as hydrates for historical reasons not covered above. Glucose, C 6 H 12 O 6, was originally thought of as C 6 (H 2 O) 6 and described as a carbohydrate. Hydrate formation is common for active ingredients. Many manufacturing processes provide an opportunity ...
γ-Cyclodextrin exists as a white (colorless) powder or crystals. The density of its hydrate crystal (γCD·14H 2 O) is 1.41 g/cm 3 . γ-Cyclodextrin is well soluble in water and dimethyl sulfoxide , poorly soluble in methanol .
Minerals that are chemical hydrates, including molecules of water in their crystal structure. Subcategories This category has the following 7 subcategories, out of 7 total.
There are two main ways in which minerals hydrate. One is conversion of an oxide to a double hydroxide , as with the hydration of calcium oxide —CaO—to calcium hydroxide —Ca(OH) 2 . The other is with the incorporation of water molecules directly into the crystalline structure of a new mineral, [ 1 ] as with the hydration of feldspars to ...
This metal aquo complex crystallizes with water of hydration, which interacts with the sulfate and with the [Fe(H 2 O) 6] 2+ centers. A salt with associated water of crystallization is known as a hydrate. The structure of hydrates can be quite elaborate, because of the existence of hydrogen bonds that define polymeric structures.

Clathrate hydrate, which encaged CO 2 as guest molecule is termed as CO 2 hydrate. The term CO 2 hydrates are more commonly used these days with its relevance in anthropogenic CO 2 capture and sequestration. A nonstoichiometric compound, carbon dioxide hydrate, is composed of hydrogen-bonded water molecules arranged in ice-like frameworks that ...
Though bicchulite is an aluminosilicate, it is the only one to have an Al to Si ratio of 2:1 and have a framework structure. [10] Bicchulite is also a sodalite-type mineral not only because of its similar composition components of Na 6 (Na,Ca) 2 (Al 6 Si 6 O 24 )X 1−2n •H 2 O , but also because of its analogous structure.
