Document Summary
Although cells are 70-90% water, the rest consists mostly of carbon. Proteins, dna, carbohydrates & other molecules found in all living matter: each is composed of carbon. Atoms bonded to each other: and to atoms of other elements. Carbon"s importance to life arises from its versatile bonding behavior. One carbon atom can bind up to. The number & arrangement of functional groups give each molecule its unique properties. There are six functional groups that are important to the chemistry of life. All are hydrophilic and increase solubility of organic compounds in water. Some act as bases, other as acids: most readily to h atoms, o atoms, other c atoms. Carbon atoms together with other atoms form molecules of various sizes: many biological molecules are macromolecules. Skeleton contributes to the diversity of organic molecules. Variation in the carbon arranged in closed rings them. Non-polar & do not dissolve in water.
