Suggestions

As a new editor, here are some suggestions:

• Editors here do not like patents as sources. They are viewed as unreliable and nearly inaccessible. The best sources are books and review articles.
• Please omit English from artwork. The words can go into the caption. Removing English means that other languages can use the artwork.
• Wikipedia avoids giving instructions or detailed methodology. That A + B gives C is usually enough. Solvent, temp, etc are not of encyclopedic interest, usually.

Good luck and feel free to ask around.--Smokefoot (talk) 12:17, 15 November 2019 (UTC)

Featured picture scheduled for POTD

The citric acid cycle, also known as the TCA cycle (tricarboxylic acid cycle) or the Krebs cycle, is a series of chemical reactions to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins. In addition, the cycle provides precursors of certain amino acids, as well as NADH, a reducing agent, which are used in numerous other reactions. Its central importance to many biochemical pathways suggests that it was one of the earliest components of metabolism and may have originated abiogenically. The German-born British biochemist Hans Krebs received the 1953 Nobel Prize in Physiology or Medicine for his identification of the cycle in 1937. The name of this metabolic pathway is derived from citric acid, which is consumed and then regenerated by this sequence of reactions to complete the cycle. The cycle consumes acetate (in the form of acetyl-CoA) and water, and reduces NAD⁺ to NADH, releasing carbon dioxide. The NADH generated by the cycle is fed into the oxidative phosphorylation (electron transport) pathway. The net result of these two closely linked pathways is the oxidation of nutrients to produce usable chemical energy in the form of adenosine triphosphate. These processes are depicted in this overview diagram of the citric acid cycle.
