Document Summary
Broad range of organic molecules that dissolve easily in organic solvents, but much less soluble in water. Vitamins a, d, e, k are lipid soluble; not soluble in water. Classification: hydrophobic ( water-fearing , lipophilic ( fat-loving ); fat molecules can move easily through membranes, no energy or transporters needed; just uses concentration gradient, both classifications have different degrees of solubility. Main classes of lipids: triglycerides (also called triacylglyerols, phospholipids, sterols. 109: phospholipids, makes up approximately 2% of all dietary lipids, plant and animal sources, soluble in fat and water, major constituent of cell membranes. 18:0 (# carbon atoms in that particular fatty acid : type of chem. Fatty acid notation: bonds between carbon atoms, 0 means there are 0 double bonds); 18:0 fatty acid is saturated, all potential binding sites are occupied; all chem connections are occupied by carbon or hydrogen atoms. Example: butyric acid (4:0) provides the flavour in butter. 18:0*, chocolate, meat fats, solid at room temp.
