Table 32.1: Properties of common amino acids founds in protein.

 

AROMATIC R Groups: The R group in this amino acids are hydrophobic side chain. Examples include are Phenylalanine, tyrosine and tryptophan.

POLAR, Uncharged R Groups: The R group in this amino acids are uncharged and they are more polar than hydrophoc amino acids. Examples include are serine, threonine, cysteine, asparagines and glutamine.

POSITVELY Charged R Groups: The R group in this amino acids are acidic with net negatie charge. Examples include are aspartate and glutamate.

NEGATIVELY Charged, R Groups: The R group in this amino acids are basic with net positive charge. Examples include are Arginine and Lysine.
