肽键的二面角有个名字,omega。 Omega的角度在顺式键和反式键构象时分别是0和180度。 我们来看看phi 和psi二面角的角度大小是如何用数字来表示的。为了测定phi角度,你要从N端沿着氮和alpha碳之间的键的方向看。然后测量两个羰基碳之间的夹角。 同样,要测量psi角,你要从n端沿着alpha C到羰基碳的方向看,然后测量...

刚性肽键限制了多肽链可能的构象范围。 肽构象由三个二面角(也称为扭转角)定义,分别称为ϕ(phi)、ψ(psi)和ω(omega),反映了肽骨架中三个重复键的旋转情况。二面角是两个平面相交处的角度。对于肽,平面由肽骨架中的键矢量定义。两个连续的键矢量描述一个平面。三个连续的键矢量描述两个平面(中心键矢量对两者...
