Unsaturated= Double bonds Saturated= Single bonds Phospholipid contains 2 fatty acid one phosphate group and a glycerol Phospolipid= membrain structure Triglyceride= engergy store COOH= carboxlic acid RCOOH= variable hydrocarbons Carbon, Hydrogen and Oxygen- Triglycerides Phophate, Carbon, Hydrogen and Oxygen- Phospolipids Hydrolysis= Add water, break bonds Condensation= remove water, join bonds Grind substance with pestle and mortar. Add ethanol- leave for a bit add distilled water, put on bung and shake. Posative= White Emulsion Negative= Stays the same BIle salts produced in liver, they emulsify lipids 1 of 3 Cells Cell membrane- Controles what enters and leaves the cell. Micro Villi- Increase surface area for absorbsion Mitrochondrion- Produces ATP and relises energy Rough Endoplasmic Reticulum and Ribosomes- Fold and Synthasise protiens The Golgi Body- Package and process protiens and lipids Smooth Endoplasmic Reticulum- Makes lipids Lysosomes-Digest parts of old cell Vesicles-Stoor and transport protiens around the cell Nucleolus- Make ribosomes Cell Nucleus-Contains DNA which codes for different protiens 2 of 3 Proteins and Enzymes Dentaturing- Loosing 3D shape. Caused by change in temp. High change in pH Alpha Helix- Peptide weak hydrogen bonds Induced fit- Active site changes to shape of the substrate Protiens- For anibodys Monomer that protiens are made of is Amino Acid Biret test- Add Biret A+B and shake if the substance turns purple it is posative Quaternary Structure- Association of many polypeptide bonds 3 of 3
