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 ...
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.
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. [ 3 ] [ 4 ] Historically, the structures of many hydrates were unknown, and the dot in the formula of a hydrate was employed to specify the ...
In inorganic chemistry, mineral hydration is a reaction which adds water to the crystal structure of a mineral, usually creating a new mineral, commonly called a hydrate.. In geological terms, the process of mineral hydration is known as retrograde alteration and is a process occurring in retrograde metamorphism.

These "cages" are unstable when empty, collapsing into conventional ice crystal structure, but they are stabilised by the inclusion of the gas molecule within them. Most low molecular weight gases (including CH 4 , H 2 S, Ar, Kr, and Xe) will form a hydrate under some pressure-temperature conditions. [ 3 ]
Methane clathrate block embedded in the sediment of hydrate ridge, off Oregon, USA. Clathrate hydrates, or gas hydrates, clathrates, or hydrates, are crystalline water-based solids physically resembling ice, in which small non-polar molecules (typically gases) or polar molecules with large hydrophobic moieties are trapped inside "cages" of hydrogen bonded, frozen water molecules.
Hydromagnesite is a hydrated magnesium carbonate mineral with the formula Mg 5 (CO 3) 4 (OH) 2 ·4H 2 O.. It generally occurs associated with the weathering products of magnesium containing minerals such as serpentine or brucite.
