Stoichiometry of the stearoyl-CoA desaturase should be convinced correct. Concept Introduction: In eukaryotes, addition of double bond to fatty acids does not occur until the fatty acid chain occupied its full length. But the dehydrogenation of stearoyl-CoA occurs in the middle of the chain Stearoyl-CoA + NADH + H + + O 2 → Oleoyl-CoA + 2 H 2 O Above reaction is catalyzed by stearoyl-CoA desaturase enzyme. This enzyme has a nonheme iron center. NADH and O 2 is required to run this reaction. As well as, two other proteins cytochrome b 5 reductase and cytochrome b 5 are needed. These three proteins are incorporated with ER membrane.

Hair grows at a rate of about 20 cm/yr. All this growth is concentrated at the base of the hair fiber, where a-keratin filaments are synthesized inside living epidermal cells and assembled into ropelike structures. Two-chan 14 Protofilament 20-30 A Two-chain Intermediate flament -Protob Protofilament Cross section of a hair The fundamental structural element of a keratin is the a helix, which has 3.6 amino acid residues per turn and a rise of 5.4 A perlum. 54A (36) Amino terminus Carbon Hydrogen Oxygen Nitrogen group Carboxyl terminus Assuming that the biosynthesis of a helical keratin chains is the rate-limiting factor in the growth of hair, calculate the rate at which peptide bonds of a-keratin chains must be synthesized (peptide bonds per second) to account for the observed yearly growth of hair. 0422 rate of peptide bond formation: Income bonds/s
