How much ATP is produced from stearic acid?
120 ATP
The answer is b. 120 ATP. Stearic acid is an 18-carbon saturated fatty acid. It will undergo 8 rounds of beta-oxidation to produce 9 Acetyl CoA…
What dissolves stearic acid?
Stearic acid is soluble in organic solvents such as ethanol, DMSO, and dimethyl formamide. The solubility of stearic acid in these solvents is approximately 20, 10, and 30 mg/ml, respectively.
Is stearic acid and magnesium stearate the same?
Magnesium Stearate in the Body After magnesium stearate is broken back down into its component parts in the body, its fat is essentially the same as that of stearic acid. The magnesium part of it can be used to supply the body with this essential mineral.
How many ATP are produced from stearic acid and beta oxidation?
From the Beta oxidation process: The P/O ratios, which give the number of ATP produced per molecule, are 1.5 for FADH 2, 2.5 for NADH, and 10 for acetyl-CoA.
How many ATP are produced from a 20 carbon fatty acid?
1,200 ATP molecules
A) About 1,200 ATP molecules are ultimately produced per 20-carbon fatty acid oxidized. B)
Why does stearic acid melt fast?
Higher the molecular weight, higher the melting point. For example, stearic has a melting point of 69oC whereas palmitic acid has 63oC. As the chain length increases, the Van der Waals forces between fatty acid molecules increases thereby intermolecular forces increase. This results in an increase in the melting point.
Where does the energy from fatty acid beta oxidation come from?
In tissues with high energy requirement, such as heart, up to 50–70% of energy, in the form of ATP production, comes from fatty acid (FA) beta-oxidation. During fatty acid β-oxidation long chain acyl-CoA molecules – the main components of FAs – are broken to acetyl-CoA molecules.
What are the steps of beta oxidation in CPT2?
CPT2 then coverts the long chain acylcarnitine back to long-chain acyl-CoA before beta-oxidation. Beta-oxidation consists of four steps:
Where does the acetyl-CoA produced by beta oxidation go?
Acetyl-CoA generated by the beta-oxidation pathway enters the mitochondrial TCA cycle, where is further oxidized to generate NADH and FADH 2. The NADH and FADH 2 produced by both beta oxidation and the TCA cycle are used by the mitochondrial electron transport chain to produce ATP.
What are the four steps of beta oxidation?
Beta-oxidation consists of four steps: 1) Dehydrogenation catalyzed by acyl-CoA dehydrogenase, which removes two hydrogens between carbons 2 and 3. 2) Hydration catalyzed by enoyl-CoA hydratase, which adds water across the double bond. 3) Dehydrogenation catalyzed by 3-hydroxyacyl-CoA dehydrogenase, which generates NADH.
