Question

4. Why is more energy available from oxidation of stored fatty acids than from oxidation of an equivalent weight of glycogen?

5. How much ATP is generated by the oxidation of the following fatty acids? Assume that the citric acid cycle is functioning. a. Stearic acid (octadecanoic acid) b. Oleic acid (cis-delta9-octadecanoic acid)

Answer 1

4 oxiclation of fally acids gives more energy than oxiolation «6 1-усел» Glycogen is a kind of polycarte bancle ['lorbomophorife] (monomev - gucose) Fally cocid is a carboxylic acid with long aliphalic chain (Satuvölled or unsaturated) y Glycogen (carbohydrates) are carbanlyl compound containing Slouctures. ( contain many eo bends ) less oxidation possible - Due to long caliphatic chain, they can be reduced more as compare to glycogen, or in other way I Can Say Carbon atom of fally acids have higher oxidation states as compare to glycogen. (means more number of electrons bround fally acids) Consequently more energy is nopeased to released when these elections are transferred to oxygen. (when oxidized). Secondly fally acids are hydrophobic in nature cond ( do not carry any head for hydration, hence energy is not lost in hydration where as polysaccharide have to carry extra weight of water of hydration) hence some enengy lost in that." Moreover fally ands also involves oxidation processes like beta oxiclation, a producing energy releasing FADH2 and NADH etc. hance
