Methionine is an amino acid and like some amino acid, it has a zwitterion form. A zwitterion form is a form of molecule showing separate positive and negative charges. The hydrogen from the carboxylic acid group will transfer to the amino group producing a negative charge at the carboxyl group and a positive charge at the amino group.

Explanation :

Zwitter ion : An ion or molecule having separate negatively and positively charged groups.

Methionine is an amino acid with sulfur atom in its molecule .The proton from carboxylic group with get attached to amino group present in the methionine and negative charge will be generated on oxygen atom of a carboxylic group which will get in conjugation with an another oxygen atom of the carboxylic group.

The positive charge will generated on the nitrogen atom due  attachment of the proton from the carboxylic group.
