应用
聚甘氨酸已被用作外部强度标准品，用于测量交叉极化 (CP) 核磁共振 (NMR) 谱测量 和离子迁移质谱。适用于作为紫外共振拉曼光谱研究的模型。
生化/生理作用
多甘氨酸以两种形式存在，即具有反平行 β-片状结构和延伸 31 螺旋的多聚甘氨酸 II (PGII)。它是一种最灵活的多肽，具有最小的空间位阻，在锂离子存在下溶解度增加。存在于哺乳动物和植物中。与叶绿体膜蛋白 Toc5 相关的多聚甘氨酸伸展对于囊膜分选是必需的。
制备说明
通过磷酸化制备。

Two main onsets of anharmonicity are present in protein dynamics. Neutron scattering on protein hydrated powders revealed a first onset at about 150 K and a second one at about 230 K (the so called dynamical transition). In order to
