Which one of the following amino acids does not fit alpha helical structure of the proteins?

Understand the Problem

The question is asking which amino acid among the given options does not conform to the alpha helical structure typically found in proteins. This requires understanding the structural properties of amino acids.

More Information

Proline disrupts alpha-helices because its cyclic structure limits the flexibility necessary for maintaining the helical shape.

Tips

Avoid assuming that all amino acids fit well into all protein structures without considering their specific properties.
