Simply so, is proline polar or non polar?

From Pearson Prentice Hall's Biological Science, it states that Proline is nonpolar, Tyrosine is polar and Cystein is polar. From BioNinja, it states that Proline is nonpolar, Tyrosine is polar and Cysteine is nonpolar.

Beside above, is proline hydrophobic or hydrophilic? Hydrophobic Amino Acids Amino acids are grouped according to what their side chains are like. The nine amino acids that have hydrophobic side chains are glycine (Gly), alanine (Ala), valine (Val), leucine (Leu), isoleucine (Ile), proline (Pro), phenylalanine (Phe), methionine (Met), and tryptophan (Trp).

Furthermore, is tyrosine polar or non polar?

Tyrosine has a single polar hydroxyl group that partly offsets the very non-polar benzene ring, but overall the side chain structure is be considered moderately non-polar.

Is proline charged?

Proline, on the other hand, is generally non-polar and has properties opposite to those of Gly, it provides rigidity to the polypeptide chain by imposing certain torsion angles on the segment of the structure.
