BIOL 1107 Chapter Notes - Chapter 3: Stereoisomerism, Triple Bond, Hydrogen Bond
Document Summary
Inorganic molecule: molecule without carbon in its structure. A few of the smallest carbon-containing molecules that occur as minerals/atmospheric gases (like co2) 4 major classes of organic molecules are carbohydrates, lipids, proteins, and nucleic acids. Carbon atoms bond covalently to each other and other atoms. Hydrocarbon: molecule consisting of carbon linked only to hydrogen atoms are considered inorganic. Triple bond can only occur in a 2 carbon hydrocarbon, single and double bonds are found in both linear and ring hydrocarbons. Chemical evolution: formation of the organic molecules that allowed the first forms of life to originate. Primordial earth"s atmosphere lacked oxygen and contained hydrogen, methane, ammonia, and water. Energy for evolution came from solar energy and natural sources like lightning. Functional group: small, reactive groups of atoms, each with specific chemical properties. Found in carbs, lipids, proteins, and nucleic acids. Number and arrangement in a molecule determine function of that molecule. Can participate in biological reactions, most common are.
