4770797516Fatty Acids Saturated Fatty Acid (left molecule) Found in animal fat All bonds between carbon atoms are single bonded Unsaturated fatty acid (right molecule) Found in plant oil Contains at least one double bond between carbon atoms13
4770799433Steroid Classified as a lipid Component of plasma membranes that make the membrane less fluid, more stable nonpolar and hydrophobic Many are sex hormones in vertebrates Ex: cholesterol14
4770800621Amino Acid building block of proteins There are 20 different amino acids Humans can synthesize only 12 and must ingest the other 815

4770803755Nucleic Acid Phosphate - Sugar- Nitrogenous Base18
4770804344Energy19
4770804957Enzyme Characteristics20
4770807460The reaction is exergonic because the potential energy (PE) of the products is less than that of the reactants The presence of a catalyst enables the reaction to occur at a lower temperature (In an endothermic reaction, the PE of the products is greater than the PE of the reactants) Gibbs free energy = how much free energy is available In exergonic reactions ΔG is negative21

Need Notes?

While we strive to provide the most comprehensive notes for as many high school textbooks as possible, there are certainly going to be some that we miss. Drop us a note and let us know which textbooks you need. Be sure to include which edition of the textbook you are using! If we see enough demand, we'll do whatever we can to get those notes up on the site for you!
