Question

classify these amino acids as acidic, basic, neutral polar, or neutral nonpolar. drag each item to the appropriate bin. view available hint(s) phenylalanine methionine proline serine acidic basic neutral polar neutral nonpolar lysine

Explanation:

Step1: Analyze Phenylalanine

Phenylalanine has a non - polar aromatic side - chain, so it is neutral nonpolar.

Step2: Analyze Methionine

Methionine has a non - polar sulfur - containing side - chain, so it is neutral nonpolar.

Step3: Analyze Proline

Proline has a non - polar ring - shaped side - chain, so it is neutral nonpolar.

Step4: Analyze Serine

Serine has a polar hydroxyl group in its side - chain, so it is neutral polar.

Step5: Analyze Lysine

Lysine has a basic amino group in its side - chain, so it is basic.

Answer:

Phenylalanine: neutral nonpolar
Methionine: neutral nonpolar
Proline: neutral nonpolar
Serine: neutral polar
Lysine: basic
