Allergic reactions cause your body to release chemicals that can make your skin swell up in hives. People who have other allergies are more likely to get hives than other people.

hydroxyl amine. It is freely soluble in water. Chemically it is a reducing agent and hence it oxidizes. It reduces ferric ion and converts into ferrous ion. Thermally in presence of water, it decomposes . The details of the above chemical properties with reference to high temperature systems are discussed here.
This makes cholesterol an example of an amphipathic molecule â part water-soluble, part water-insoluble. The picture below demonstrates this property. In the picture above, the water molecules form a cage around the polar hydroxyl group. When you dissolve sugar in water, each sugar molecule is bound up in a similar cage, surrounded by a cluster of water molecules. But most of the cholesterol molecule has no attraction to the water.
