Can anyone explain why the answer is B?

each amino acid had an amine and a carboxylic group so each amino acids will have one of each - count the number molecules which have both the amine group and carboxylic group present (so each amino acid has one double bonded oxygen and one NH)

hope this helps :smile:
if it doesn’t let me know!! i’ll try explaining another way and i can draw it out for you

thanks for your reply! I circled the ones I think will form amino acids, could you take a look and tell me if they’re right?46221811-5B6B-4576-87D4-4F4F18160B7E.jpg.jpeg

you exclude the last 2 as the question says DIFFERENT amino acids and the last 2 are the same structure - have a look at this photo i attached :smile:
