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.
Organic compounds include carbohydrates, lipids, proteins, and nucleic acids (DNA and RNA). Carbohydrate s â groups of molecules that contain carbon, oxygen, and hydrogen. Hydrogen and oxygen occur in the same ratio as in water (2:1) Carbohydrates include sugars and starches.TP (adenosine triphosphate) moleculeâ adenine-containing RNA nucleotide (see Nucleic acids below) with two additional phosphate groups. Energy released in glucose catabolism is captured and stored in phosphate bonds of ATP. Lipids â molecules that are insoluble in water, but dissolve in other lipids and alcohol.
