Write with structures the overall equation of the synthesis of palmitate from acetyl-CoA only.
Write with structures the overall equation of the synthesis of palmitate from acetyl-CoA only.
(a) If [2-14C-2-3H]acetyl-CoA (see the left figure above) and an excess of unlabeled malonyl-CoA are added as substrates, how many 3H atoms are incorporated into every molecule of palmitate, and what are their locations? How many 14C atoms are incorporated and what are their locations? (b) If unlabeled acetyl-CoA and an excess of [1,3-14C-2-3H]malonyl-CoA (see the right figure above) are added as substrates, how many 3H atoms are incorporated into every molecule of palmitate, and what are their locations? How...
Why is the conversion of pyruvate to acetyl-CoA considered irreversible in animals? Why is acetyl-CoA only considered ketogenic and not glucogenic, even though it enters the TCA cycle to form citrate? How do plants make acetyl-CoA glucogenic?
8. Draw the overall coupled reaction showing the conversion of pyruvate into acetyl CoA. dono STEP 2 nach do not ww what are true. Ir raise, change one word in the statement so that it is true. a. The pyruvate produced from glycolysis must be consumed in some way or glycolysis stops. b. Glycolysis produces ATP directly. too C. Glycolysis breaks down glucose into acetyl CoA. d. Glycolysis is aerobic
Write out all of the steps of palmitate synthesis and include enzymes
A) Write the overall reaction for step 5 of the TCA Cycle (succinyl-CoA -> succinate), showing structures for succinyl- CoA and succinate. Be sure to include the other molecules that take part in this step (there should be another reactant besides succinyl-CoA and two other products besides succinate). B) Step 5 is an example of an acyl transfer reaction. Circle the atoms in succinyl-CoA that make up the acyl group being transferred.
Please answer all. Draw the structures of the following coenzyme molecules: 1. COA-SH/Acetyl-S-COA 2. NADTINADH + H+ • For both: Give full name (if you copy the formula from an Internet source, please cite it properly, for example, according to the Chicago Manual of Style. • Indicate what are the chemical groups that are active in these molecules, i.e., what group participates in metabolic reactions (be aware that both molecules may be involved in both anabolic and catabolic processes). •...
1. Assume that the following acyl-CoA is degraded by beta-oxidation, draw the intermediate (compound) structures during one cycle of beta-oxidation. Give the NADH or FADH2 where appropriate m ioco 2. Below is a part of fatty acid synthesis. Draw individual intermediates during the synthesis from acetyl-CoA to butyryl-CoA. Indicate where ATP or NADPH is used. is.com Escon - is.com

You have made malonyl-CoA from marked CO2 and unmarked acetyl-CoA. Then you are using this malonyl-CoA to synthetized a C12:0 fatty acid. The final product will be radioactive at which carbons?
Which of the following can be converted to acetyl-CoA? glucose only glucose and fatty acids Oglucose, fatty acids, and ketogenic amino acids fatty acids only
