The basic structure of a steroid differ from other macromolecules such as carbohydrates by having a four ring structure whereas a carbohydrate do not have. A steroid is a group of organic substances which has four rings that are arranged in a certain configuration. Examples are testosterone, estradiol and lipid cholesterol. It will always have seventeen carbon atoms in its structure. Carbohydrates, on the other hand, are a group of organic substances that consist carbon, hydrogen and oxygen atoms typically in a 2:1 ratio of the hydrogen and oxygen atoms. So, it would have an empirical formula of Cx(H2O)y.
Water's high heat capacity is a property caused by hydrogen bonding among water molecules. When heat is absorbed, hydrogen bonds are broken and water molecules can move freely. When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy
