4: Lipids Flashcards
heterogenous group of compounds including fats, oils, waxes, and other compounds related based on their physical properties
Lipids
liquid at normal room temperature except Theobroma Cacao
Fatty or Fixed Oils
semi-solid or solid at room temperature except cod liver oil
Fats
storage form of energy and are metabolic regulators
Lipids
Serve as thermal insulators
Lipids
3 Classifications of Lipids
Simple Lipids
Complex Lipids
Precursors and Derived Lipids
esters of fatty acids w/ various alcohols
Simple Lipids
esters of fatty acids with glycerol
Fats
esters of fatty acids with higher molecular weight
Waxes
esters of fatty acids containing groups in addition to alcohol and fatty acids
Complex Lipids
lipid containing fatty acids and alcohols. a phosphoric acid residue
Phospholipids
Lipids containing a fatty acid, sphingosine, and carbohydrates
Glycolipids
aliphatic CA (carboxylic acid) that occurs mainly as esters in natural fats and oils
Fatty Acids
unesterified form of fatty acids
Free Fatty Acids
usually straight chain derivatives that contains an even number of carbon atoms and can be saturated or unsaturated
Fatty Acids
