| Outline of Final Research Achievements |
Antifreeze (glyco)proteins are very large molecules found in the blood serum of Antarctic notothenioid fish and Arctic cod. While the utility of antifreeze (glyco)proteins has been expected in a variety of area in life sciences, the availability of antifreeze (glyco)proteins is strictly limited to natural resources. We herein report the design and synthesis of antifreeze (glyco)proteins with small molecular weights. Based on our novel hypothesis, "a marbled beef hypothesis", we designed a (glyco)protein containing fluorinated amino acids and sugars, i.e., galactose nona-fluorinated proline (Gal-F-Pro9) as a material which demonstrates the hypothesis. The synthesis of Gal-F-Pro9 was achieved by the Click reaction of nona-fluorinated proline and propargyl-galactose. As our expectation, Gal-F-Pro9 showed an inhibition of ice recrystallization.
