How many ATP are produced per fatty acid?
Complete oxidation of one palmitate molecule (fatty acid containing 16 carbons) generates 129 ATP molecules.
How many ATP will be produced in the metabolism of arachidonic acid?
Arachidonic acid is 20-carbon containing fatty acid. Therefore, it will require nine cycles for complete oxidation. 10 mols of acetyl CoA formed after complete oxidation of arachidonic acid yield 120 ATP molecules. This is because each mole of Acetyl-CoA yields 12 ATPs by citric acid cycle.
How many ATP are produced from a 10 carbon fatty acid?
In addition, two equivalents of ATP are lost during the activation of the fatty acid. Therefore, the total ATP yield can be stated as: (n – 1) * 14 + 10 – 2 = total ATP….Energy yield.
| Source | ATP | Total |
|---|---|---|
| 7 NADH | x 2.5 ATP | = 17.5 ATP |
| 8 acetyl CoA | x 10 ATP | = 80 ATP |
| Activation | = -2 ATP | |
| NET | = 106 ATP |
How many ATP are produced from acetyl CoA?
12 ATP molecules
Acetyl CoA produces 12 ATP molecules accounting for 3 NADH (9 ATP), 1 FADH2 (2 ATP) and 1 GTP (1 ATP) in the TCA cycle and oxidative phosphorylation in the electron transport system.
How many ATP are produced from a 22 carbon fatty acid?
This gives us a grand total of 31 NADH, 15 FADH2 and 8 GTP molecules. The 31 NADH produce 77.5 ATP while the 15 FADH2 produce 22,5 ATP along the electron transport chain. The 8 GTP are transformed into 8 ATP. This gives us a total of 108 ATP molecules.
How many ATP are produced from one Acetyl Co A?
How many ATP are produced from a 8 carbon fatty acid?
The 8 GTP are transformed into 8 ATP. This gives us a total of 108 ATP molecules. However, since 2 ATP molecules were used up in the activation of the fatty acid, this means that 106 ATP molecules are generated when a single palmitic acid is broken down via beta oxidation.
What is the total ATP yield of oxidation of stearic acid?
Therefore, the total ATP yield of oxidation of stearic acid is 120 ATP. Linoleic acid also has 18 carbons like stearic acid, but it has two double bonds in its structure. This results in two less FADH 2 being produced, resulting in a total of 9 acetyl-CoA, 6 FADH 2, and 8 NADH as the products.
Is stearic acid a long chain fatty acid?
Stearic acid (18 carbons) is a long chain fatty acid (LCFA). The very long chain fatty acids (VLCFA; 22 or more carbons) have initial beta oxidation in peroxisomes, down to short or medium chain length.
What is the IUPAC name of stearic acid?
The IUPAC name is octadecanoic acid. It is a waxy solid and its chemical formula is C 17 H 35 CO 2 H. Its name comes from the Greek word στέαρ ” stéar “, which means tallow. The salts and esters of stearic acid are called stearates. As its ester, stearic acid is one of the most common saturated fatty acids found in nature following palmitic acid.
How is stearic acid made from triglycerides?
Production. Stearic acid is obtained from fats and oils by the saponification of the triglycerides using hot water (about 100 °C). The resulting mixture is then distilled. Commercial stearic acid is often a mixture of stearic and palmitic acids, although purified stearic acid is available.
