Hypothesis: any combination of Phe and Tyr that sums up to six with any charged chain gives purple

Experiment: We tested blobs of Tyr mixed with Phe of a total of six with chains of charged amino acid and observed the results

Results: a fixed ratio of 7:6 phobic blob of phe and tyr:charged chain gives purple

Conclusion: the amino acids that determined the blue and red protiens, when mixed to a total of 6 with any charged chain, give purple

Hypothesis: If you switch a hydrophobic amino acid out for a hydrophilic the color will change.

Experiment: We started with a yellow protein and changed the hydrophilic Arg to a hydrophobic Leu.

Result: When changing a hydrophilic to hydrophobic at any point in the amino acid sequence there was a change in shape which results in a loss of color.

Conclusion: Switching hydrophobic to hydrophilic will result in a loss of color.

Hypothesis: a blob of phe with a chain of any positive charge gives a red protien

Experiment: We tried different ratios of Phe to different positvely charged amino acids

Result: a fixed ratio of 7:6 Phe:any positively charged amino acid gives a red protien

Conclusion: Therefore with a fixed 7:6 ratio of Phe:positive amino acid, we get a red protien

Hypothesis: Changing just one amino acid in the sequence will produce a different color

Experiment: In the above sequences we changed phe from a red protein to trp 

Result: Changing that one amino acid made the protein change to yellow from red

Conclusion: The color of a protein can depend on as little as one amino acid in its sequence

Hypothesis: Changing the philic amino acid arginine with a less philic amino acid asparanine will not change the color of the protein.

Experiment: We changed the arginine to asparanine.

Result:Changing arginine to asparanine resulted in a change of structure and a loss of the color green.

Conclusion: Changing arginine to asparanine results in a colorless protein.

Hypothesis: The color depends on the fouth to last amino acid

Experiment: We changed Val of white to Phe.

Result: By changing Val to Phe we recieved a red protein

conclusion: our hypothesis was proven correct.

HYPOTHESIS: The color depends on the TRP protein of yellow. (The fourth to last protein)

EXPERIMENT: By replacing an existing protein with a different protein, would be able to clarify if the protein would actually affect the colors.

RESULTS: When we changed TRP to TYR, the color yellow changed to blue. When changing TRP to any other protein, it lost its color.

CONCLUSION: From our experimentation, we concluded that our hypothesis was somewhat right.

Hypothesis: A hydrophobic blob of 8 amino acids will be red

Experiment: We made a hydrophobic blob of 8 amno acids

result: The color came out to be colorless

Conclusion: Our hypothesis was incorrect

Hypothesis: The shape of a protein determines its color.

Experiment: We observed the structure of red and green proteins.

Result: The structure of the proteins are the same.

Conclusion: The structure of the proteins does not determine the color of the flower.
