The temperature dependence of atomic fluctuations in heparan sulfate was measured for different time-scales between the picosecond and the nanosecond. The data established the role of hydration for the emergence of high-amplitude motions at 200-240 K, and the higher resilience of the polysaccharide compared to proteins measured under similar conditions.
研究人员测量了不同时间尺度(皮秒到纳秒)下肝素硫酸盐中原子波动的温度依赖性。这些数据确定了水合作用在 200-240 K 时出现高振幅运动的作用,以及在相似条件下测量的多糖比蛋白质具有更高弹性的原因。
