Answer: X is propionyl-CoA, CH3CH2C0CoA
The structure and reaction pathway are shown in the attachments.
Explanation: In the oxidation of odd-number fatty acids, the substrate for the last pass through beta-oxidation is fatty acyl-CoA with a five-carbon fatty acid. This is oxidized and cleaved to acetyl-CoA and propionyl-CoA. Acetyl-CoA enters the citric acid cycle while the propionyl-CoA is converted in three enzymatic steps to succinyl-CoA which can then enter the citric acid cycle.
Step 1: Conversion of propionyl-CoA to D-methylmalonyl-CoA
Propionyl-CoA is carboxylated to D-methylmalonyl-CoA by the enzyme <em>propionyl-CoA carboxylase</em>, which contains the cofactor <em>biotin</em>. A molecule of ATP and Carbon (iv) oxide (in the form of hydrogen carbonate ion) is required also.
Step 2: Epimerization of D-methylmalonyl-CoA
D-methylmalonyl-CoA is epimerized by the enzyme <em>methylmalonyl-Co epimerase</em> to its L stereoisomer, <em>L-methylmalonyl-CoA.</em>
Step 3: Conversion of L-methylmalonyl-CoA to succinyl-CoA
This reaction is catalysed by <em>methylmalonyl-CoA mutase</em> which requires the <em>coenzyme B12.</em>

Here's what I get
Explanation:
The image below shows how a topographic map displays contours, contour intervals, and hachure marks.
The contour interval is 20 m and you are on the 340 m contour.
Its called osmosis and it only happens with water. now I'm just adding words to be able to post this. its moving down the concentration gradient.
Two important natural processes that release carbon into our atmosphere are photosynthesis and respiration.
Answer:
Hello. You did not add the necessary graphics for this question to be answered. However, I can help you by showing that one of the procedures that a medical team can do to inhibit the action of trypsin in the deorization of the pancreas is the use of ulinastine.
Explanation:
During the process of isolating a pancreas to be transported, the use of ulinastine is shown to be efficient for inhibiting trypsin, which promotes deterioration of the pancreas. Unilastine is also an anti-inflammatory, which will bring even more benefits with its use.
Thus, with the use of a ulinastine solution, the pancreas has more time to reach the transplant site and promote successful surgery.
