This image shows the <scene name='Sandbox_32/Polar_versus_nonpolar/2'>polarity</scene> of the residues in the protein. The polar areas of the protein are shown in pink, while the non-polar areas of the molecule are shown in light blue. The polarity of the individual amino acid residues can be seen better in the <scene name='Sandbox_32/Polar_vs_non_stick/1'>stick model</scene>. The polar amino acid residues are again shown in pink, while the non-polar amino acid residues are shown in blue. By rotating the two representations of the polar versus non-polar areas of the protein to an aerial view, it can be seen that the polar (hydrophilic) areas are located toward the outside of the protein, while the non-polar (hydrophobic) areas are located toward the inside of the protein. | This image shows the <scene name='Sandbox_32/Polar_versus_nonpolar/2'>polarity</scene> of the residues in the protein.

Trypsin
Trypsin is a medium size globular protein that functions as a pancreatic serine protease. Trypsin was first discovered in 1876 by Kuhne, who investigated the proteolytic activity of the enzyme.
Structure
The of the protein can be followed from N-terminus of the protein (blue) to the C-terminus of the protein (red).
Trypsin has many important structural aspects. The

Polar vs. Nonpolar Residues
This image shows the of the residues in the protein. The polar areas of the protein are shown in pink, while the non-polar areas of the molecule are shown in light blue. The polarity of the individual amino acid residues can be seen better in the . The polar amino acid residues are again shown in pink, while the non-polar amino acid residues are shown in blue. By rotating the two representations of the polar versus non-polar areas of the protein to an aerial view, it can be seen that the polar (hydrophilic) areas are located toward the outside of the protein, while the non-polar (hydrophobic) areas are located toward the inside of the protein.
Contacts Between Structural Components and Remainder of the Protein
Charge
The charge of the different components of Trypsin are shown in this figure . The cationic (+) atoms are shown in blue, while the anionic (-) are shown in red. These charged aspects of the protein face the outside environment surrounding the protein. The light purple parts of the protein are uncharged and the gray portions of the protein are hydrophobic. The charged and uncharged portions of the protein directly relate to the hydrophilic and hydrophobic character of the protein.
