核磁共振光谱NMR光谱 核磁共振波谱，常用NMR表示，与红外光谱、紫外光谱一样，也是一种能谱。测定这种能谱的依据，是一些原子核（如1H、13C、19F等）在磁场中会产生能量分裂，形成能级。当用一定频率的电磁波对样品进行照射时，特定结构环境中的原子核就会吸收相应频率的电磁波而实现共振跃迁。在照射扫描中记录共振时...
Unlike CPPs, AMPs have well-defined secondary structures as well as lower molecular dynamics, leading to their distinct biological activities (Table 1). The intra- or intermolecular H-bondings and oligomerization, such as β-barrels in PG-1, immobilize the backbone of AMPs [31]. The PG-1 ...
