Alanine (Ala): A non-polar amino acid that provides structural flexibility.
Glutamic Acid (Glu): A polar, charged amino acid that aids in stability and water solubility.
Aspartic Acid (Asp): An acidic amino acid crucial for the peptide’s biological binding and activity.
Glycine (Gly): The smallest and most flexible amino acid, allowing the peptide to achieve its bioactive shape.
