Always the number of peptide bonds in a linear protein can be calculated using the formula (n-1), where n is the number of amino acids present in the protein.

Where in a protein molecule would you find a hydrophilic amino acid? Simple answer: On the outside, facing away from most other amino acids (hydrophilic side chains are "water liking" and repelled away from the non-polar side chains of most other residues). Why are some amino acids hydrophilic? As the others have said, it's to do with the charge on the side chain. Polar side chain (e.g. Ser, Tyr, Asp) = hydrophilic, non-polar side chain (e.g. Ala, Val, Leu) = hydrophobic. I was a peptide chemist in a former life... before I became analytical but that's another story.

437..a peptide bond is a linkage between two amino acids
