Question

Name 4 things attached to the center carbon in all amino acids

Answer 1

Aminoacids have an amine (Nh2) group, a COOH group and a side-chain, joined by a center carbon: so the center carbon attaches to the N of the amine group, to the C of the COOH group, to another H and to the side-chain, which is different for each aminoacid (and it's usually written as "R")
I hope that my answer is helpful! Let me know if you need something more :)

Answer 2

All amino acids have a center carbon. The center carbon has four different molecules attached to it, these are: AMINO GROUP [NH2], CARBOXYL GROUP [COOH], AN R GROUP [R] AND A HYDROGEN ATOM. There are twenty different amino acids in existence, each amino acid differ from another one based on their R groups. The R group is specific and unique to each amino acid. The center carbon in amino acid structure is also called alpha carbon.
