Document Summary
Structure: what are the organic molecules, polymer principles, carbohydrates- fuel and building material, lipids- diverse hydrophobic molecules, proteins- the molecular tools of the cell, nucleic acids- informational polymers, organic molecules. Organic molecules are those that: formed by the actions of living things; and/or, have a carbon backbone. Carbon has four electrons in outer shell, and can bond with up to four other atoms (usually h, o, Since carbon can make covalent bonds with another carbon atom, carbon chains and rings that serve as the backbones of organic molecules are possible. The c-c covalent bonds has 83. 1 kcal per mole while the c=c double covalent bond has. Ek or energy in use/motion: ep or energy at rest or in storage (chemical bonds) Chemical bonds are potential energy until they are converted into another form of energy (according to law of thermodynamics) Methane (ch4) is an example of this. Molecules made of h and c are known as hydrocarbons.
