alpha- amino acids are

Which of the following is not an alpha -amino acid?

Carboxylic acids containing an amino group (-NH_(2)) as a substituent are called amino acids. When this amino group substitution is at alpha position with respect to carboxylic group, the aminoacid is called alpha -amino acid. The aminoacids with two carboxylic acids are called acidic amino acids whereas aminoacids with two amino group are called basic amino acids Amino acids show amphoteric character. Ali chiral natural amino acids exist in L-form. : What would be the net charge on the given amino acid at pH=14?

Assertion- Protein forming amino acids are alpha -amino acids. Reason- In all protein forming amino acids, -NH_(2) groups is attached to second C-atom after -COOH group

Which of the following is not an alpha -amino acid? Cysteine, Tyrosine, Trypsin, Proline, Serine
