- Rank the fatty acids in each group in order of increasing melting point. A<C<B B<C<A B>C>A A>C>BIllustrate the asked organic compounds in the first picture. In the second picture, name the monosaccharides and their glycosidic bond.Explain why saturated (flat) fatty acids cause more plaque in blood vessels than unsaturated (gnarled) fatty acids. (Hint: First explain how lipid molecules are attracted to each other.)
- 70 degree Celcious is the melting point of stearic acid, and 4 degree Celcius is the melting point of oleic acid. Explain using the concept of lipids why their melting point is so different.Complete hydrolysis of a glycerophospholipid yields glycerol, two fatty acids (16:1(Δ9) and 16:0), phosphoric acid, and serine in the molar ratio 1:1:1:1:1. Name this lipid and draw its structure.Compositional analysis of a certain lipid shows that it has exactly one mole of fatty acid per mole of inorganic phosphate. Could this be a glycerophospholipid? A ganglioside? A sphingomyelin?
- Determine the chemical formula for each of the following carbohydrates. Use the ratio for carbohydrates to fill in the missing number in the chemical formula. Example: C3H?O3 = C3H6O3 1:2:1 ratio Carbon 1 x 3 = 3 Hydrogen 2 x 3 = 6 Oxygen 1 x 3 = 3 C6H__O6 C5H__O5 C7H__O7 C4H__O4Give each of the following structural units: oils and fatswaxesglycerophospholipidssteroids sphingolipids glycolipids sphingolipidsprostaglandins terpenesMatch each fatty acid with its melting point.
