335471 Amino acids are called α -amino acids. Why?

1 Amino acids are organic compounds containing an amino group and acidic group as substituents on two different carbons
2 Amino acids are organic compounds containing an amino group and an acidic group as substituents on the same carbon
3 Amino acids are inorganic compounds containing an amino group and acidic group as substituents on two different carbons
4 Amino acids are inorganic compounds containing an amino group and acidic group as substituents on the same carbon.
