In biochemistry, a Ramachandran plot (also known as a Rama plot, a Ramachandran diagram or a [φ,ψ] plot), originally developed in 1963 by G. N. Ramachandran, C. Ramakrishnan, and V. Sasisekharan, [1] is a way to visualize energetically allowed regions for backbone dihedral angles ( also called as torsional angles , phi and psi angles ) ψ ...
Such an approach is used, for example, in describing the motion of a rigid body; the position and orientation of a rigid body can be described by six independent, unconstrained coordinates, rather than describing the positions of the particles that make it up and the constraints among them that maintain their relative distances.
The bond angles in the table below are ideal angles from the simple VSEPR theory (pronounced "Vesper Theory") [citation needed], followed by the actual angle for the example given in the following column where this differs. For many cases, such as trigonal pyramidal and bent, the actual angle for the example differs from the ideal angle, and ...
The dihedral angles in the 3 10 helix, relative to those of the α helix, could be attributed to the short lengths of these helices – anywhere from 3 to 5 residues long, compared with the 10 to 12 residue lengths of their α-helix contemporaries. 3 10-helices often arise in transitions, leading to typically short residue lengths that result ...

Here’s an example. A popular online survey site, Swagbucks, pays its members anywhere from $1 to $5 daily. Some offers do pay $50 to $250, but these tend to be more intensive and time-consuming ...
a torsion angle between ±90° and 180° is called anti (a) a torsion angle between 30° and 150° or between −30° and −150° is called clinal (c) a torsion angle between 0° and ±30° or ±150° and 180° is called periplanar (p) a torsion angle between 0° and ±30° is called synperiplanar (sp), also called syn-or cis-conformation
