摘要

基于变构材料的结构和协同演化，提出了红细胞的力学模型。该模型用于解释在49.5℃时红细胞闪烁和相变（形态变化）等现象，这些现象从物理角度无法完全解释。为了描述蛋白质（特别是血红蛋白）的粘弹性，采用了先前获得的实验数据。先前获得的不同形式血红蛋白之间粘弹性特性的差异用于描述在光谱网络中打开和关闭弹簧所必需的力。

Mechanical Model of Erythrocyte: Allostery at the Cellular Level?

Based on the architecture and coevolution of allosteric materials, a mechanical model of the erythrocyte is proposed. This model is used to explain such phenomena as erythrocyte flickering and phase transitions (morphological changes) at 49.5°C, which are not fully explained from the physical point of view. To describe the viscoelastic properties of proteins (in particular, for hemoglobin), experimental data obtained earlier are taken. The difference in viscoelastic properties between different forms of hemoglobin obtained earlier is used to describe the forces that are necessary to turn on and off the springs in the spectrin network.
