Estradiol is a type of estrogen which is normally secreted by the ovaries. It can be prescribed for many uses, including the relief of menopausal symptoms or for the prevention of osteoporosis and hormone replacement in women who are deficient in estrogen.
Each class of molecule has features that determine its use in living systems. The first class of molecules are called carbohydrates. The simplest type of these, monosaccharide simple sugars, have a basic formula: for every carbon atom, there are two hydrogens and one oxygen, or one water for each carbon. Carbo - hydrate.
Carbohydrates are used for structure and energy storage. Carbohydrates, such as cellulose, are made of sugars. Carbohydrates (KAHR-boh-HY-DRAYTS) provide the cell with energy. Simple carbohydrates are sugars made from atoms of carbon, oxygen, and hydrogen.Inside cells, sugar molecules are broken down. This process provides usable energy for the cell. Simple sugar molecules can also be linked into long chains to form more complex carbohydrates, such as starch, cellulose, and glycogen.imple carbohydrates are sugars made from atoms of carbon, oxygen, and hydrogen.
