摘要:Phospholipid spin labels incorporated in the sarcoplasmic reticulum from rabbit-skeletal muscle undergo rapid lateral diffusion within the plane of the membrane. The diffusion constant, D, is 6x10-8 cm2/sec at 37{degrees}. With this diffusion constant, a phospholipid molecule can diffuse a distance of the order of 5000 nm in 1 sec.
