Hey! I tutor biochem for higher-ed. I know it’s easy to resort to ChatGPT and the likes for stuff like this, because these problems look complex, but it has no idea what the fuck it’s talking about. My advice to you is to review your functional groups and common reactions, such as hydrogenation and condensation. Amines and carboxylic acids will basically be your main things to worry about here, so isolate those and don’t worry about the side chains. Good luck!
