Inhibition of ice melting by antifreeze protein

抗冻蛋白(AFP)是几种生活在寒冷地区的生物中发现的，具有抑制冰生长的功能。预计AFP还将抑制冰川融化。然而，关于甲胎蛋白抑制熔融的报道很少。在这项研究中，AFP溶液被冰晶包围的负晶系中，基于只在负晶系中才能检测到融化抑制的假设，研究了冰晶的融化。结果表明，AFP通过作用于特定的冰晶面，在高于平衡融化温度的温度下抑制冰融。

Antifreeze protein (AFP), which has been discovered in several organisms living in cold regions, has a function to inhibit ice growth. AFP is also expected to inhibit ice melting. However, there are few reports on melting inhibition by AFP. In this study, melting of ice crystal was examined using a negative crystal system, where AFP solution is surrounded by an ice crystal, based on the hypothesis that the melting inhibition can be detected only in a negative crystal system. The results showed that AFP can inhibit ice melting at temperatures even above the equilibrium melting temperature by acting on specific ice crystal planes.
