A Ramachandran plot can be used in two somewhat different ways. One is to show in theory which values, or conformations, of the ψ and φ angles are possible for an amino-acid residue in a protein (as at top right).
Functional magnetic resonance imaging (fMRI) was employed to determine areas of activation in the cerebellar cortex in humans during a series of motor tasks. The activation areas for movements of lips, tongue, hands, and feet were determined and found to be sharply confined to lobules and sublobules and their sagittal zones in the rostral and caudal spinocerebellar cortex.
Anatomical "lines", or "reference lines," are theoretical lines drawn through anatomical structures and are used to describe anatomical location. The following reference lines are identified in Terminologia Anatomica: Anterior median line; Lateral sternal line: A vertical line corresponding to the lateral margin of the sternum.
The majority of β-strands are arranged adjacent to other strands and form an extensive hydrogen bond network with their neighbors in which the N−H groups in the backbone of one strand establish hydrogen bonds with the C=O groups in the backbone of the adjacent strands. In the fully extended β-strand, successive side chains point straight up ...
In the less extensive technique of equilibrium unfolding, the fractions of folded and unfolded molecules (denoted as and , respectively) are measured as the solution conditions are gradually changed from those favoring the native state to those favoring the unfolded state, e.g., by adding a denaturant such as guanidinium hydrochloride or urea.
A negative sign is applied to α when the ratio between the lower subtine and the width of the tine is measured. [9] These numbers apply to a large class of dynamical systems (for example, dripping faucets to population growth). [9] A simple rational approximation is 13 / 11 × 17 / 11 × 37 / 27 = 8177 / 3267 .
As the lateral portion is twisted like a screw, the two parts together take the form of an inverted Y. [4] [verification needed] Arising from the anterior inferior iliac spine and the rim of the acetabulum, the iliofemoral ligament spreads obliquely downwards and laterally to the intertrochanteric line on the anterior side of the femoral head.
For example, if the heights of two lines are found to be h 1 and h 2, c 1 = h 1 / ε 1 and c 2 = h 2 / ε 2. [14] Parameters of the line shape are unknown. The intensity of each component is a function of at least 3 parameters, position, height and half-width. In addition one or both of the line shape function and baseline function may not be ...
