Given a protein amino acid sequence (written out, 1 letter abbreviation, about 700 amino acids), how do i identify the N and C terminals? I know that N terminal is a free amine group and C is a free carboxyl group, but how do i know it is free? How do i identify it?
(References Explain why an amino acid will not exist in an un-ionized form at any pH. All amino acids have a carboxyl group that is a stronger acid than water and an amino group that is a stronger acid than water. When lots of hydrogen ions are present (meaning the pH is relatively low), the carboxyl group is protonated and the amino group is unaffected When lots of hydroxide ions are present (meaning the pH is relatively high), the carboxyl...
