Oscillations and accelerations of ice crystal growth rates in microgravity in presence of antifreeze glycoprotein impurity in supercooled water
The free growth of ice crystals in supercooled bulk water containing an impurity of glycoprotein, a bio-macromolecule that functions as 'antifreeze' in living organisms in a subzero environment, was observed under microgravity conditions on the International Space Station. We observed the acceleration and oscillation of the normal growth rates as a result of the interfacial adsorption of these ...
متن کاملBlocking rapid ice crystal growth through nonbasal plane adsorption of antifreeze proteins.
Antifreeze proteins (AFPs) are a unique class of proteins that bind to growing ice crystal surfaces and arrest further ice growth. AFPs have gained a large interest for their use in antifreeze formulations for water-based materials, such as foods, waterborne paints, and organ transplants. Instead of commonly used colligative antifreezes such as salts and alcohols, the advantage of using AFPs as...
متن کاملAnalysis of ice crystal growth for a crystal surface containing adsorbed antifreeze proteins
The adsorption of antifreeze protein (AFP) molecules to the ice crystal surface during melt growth from an AFP solution results in disturbance of the growth kinetics at the surface interface. In this paper, the growth pattern related to the potential for crystal growth as well as the crystal surface topography have been studied. The crystal shape and size were found to be strongly dependent on ...
متن کاملPerturbation of Long-Range Water Dynamics as the Mechanism for the Antifreeze Activity of Antifreeze Glycoprotein
Very little is known about the mechanism of antifreeze action of antifreeze glycoproteins (AFGPs) present in Antarctic teleost fish. Recent NMR and CD studies assisted with total synthesis of synthetic AFGP variants have provided insight into the structure of short AFGP glycopeptides, though the observations did not yield information on the antifreeze mechanism of action. In this study, we use ...
متن کاملArtificial multimers of the type III antifreeze protein. Effects on thermal hysteresis and ice crystal morphology.
A variant of antifreeze protein (AFP) named RD3 from antarctic eel pout (Lycodichthys dearborni) comprises the type III AFP intramolecular dimer, which is known to exhibit a significant enhancement of thermal hysteresis when compared with the type III AFP monomer (Miura, K., Ohgiya, S., Hoshino, T, Nemoto, N., Suetake, T., Miura, A, Spyracopoulos, L., Kondo, H., and Tsuda, S. (2001) J. Biol. Ch...
