The acetyl group (-COCH₃) is not acidic itself. The amino acid has both an acidic -COOH group and a basic primary amine (-NH₂) group, but in the compound the primary amine becomes a secondary amine (-NH-), who basicity will depend on surrounding atoms. (If you look at a structural diagram of the compound, the only hydrogen atom it can realistically lose to have acidity is on the -COOH.)

Just to be pedantic, the acidity doesn't come from the acetyl group - - it comes from the tyrosine, an amino acid.

Versteh ich das richtig, dass da ein Leerzeichen den Unterschied machen soll? Sozusagen also eine Legitimierung des Deppenleerzeichens.

Crossposting an image doesn't allow me to click on the image to enlarge it – instead it goes to the other post, in this case on another instance, so I can't even post there.

Maybe it would be better to repost the image itself, and include a Lemmy link to the other post in the text.

Kannste mal sehen, die Nazis hatten da nur einen kleinen 737. Bei der CDU ist es gleich ein doppelt so grosser 777, mit dem man auch sicher alle Herkunftsländer ohne Zwischenlandung erreichen kann

Alex Trebek, is that you?

By that measure, Lego is probably also the biggest producer of windshields, wigs, doors, windows, etc.
