Organic Molecules
2.3.1 Organic Molecules make up living Things Organic compounds: compounds that are found in living organisms and contain carbon. (there are some inorganic molecules with carbon in them like C02)
There are 4 Main types of Organic Molecules Carbohydrates Made of sugar monomers Lipids Made of fat monomers Proteins Made of amino acid monomers Nucleic Acids Made of nucleotide monomers
Amino Acids Make proteins Proteins are involved or create the following: Muscle structure Hormones Antibodies Hemoglobin Membranes
Lipids Hydrophobic molecules Major uses Fats Steroids Hormone Waxes Membrane formation
Lipid (Fatty Acids) Long Hydrocarbon chains Oils and Fats Saturated (maximum number of Hydrogens) Butter, meat, cheese Unsaturated some Carbons are double bonded Avocado, olive oil, fish 3
Carbohydrates Sugars Used for cellular respiration Maintain homeostasis Kept in blood (glucose) for immediate energy 2 kinds Monosaccharide's – one ring or one long chain Disaccharides 2 rings In sugars, every Carbon has an oxygen attached to it
Nucleic Acids Single and double ring molecules that contain Nitrogen RNA or DNA Different sugars attached to them Stores your genetic information
Amino Acids
Carbohydrates
Fatty acid (in this case, palmitic acid) Figure 5.10 Fatty acid (in this case, palmitic acid) Glycerol (a) One of three dehydration reactions in the synthesis of a fat Ester linkage (b) Fat molecule (triacylglycerol)
Nucleic Acids
3.2.6 - 3 Roles of Lipids Long term storage (fat in animals, oils in plants) Insulation Buoyancy
3.2.7 Compare energy storage of carbs vs lipids Carbs short term / lipids long term Carbs soluble (easy transport) Lipids lighter weight, more energy per gram
