In almost all aircraft, the flight controls are movable aerodynamic surfaces attached to a main lifting body. When the moving part or the surface is moved, the aerodynamic characteristic of the main surface is changed which allows ...

[2] The increased PTH secretion, in turn, causes increased calcium in the blood by acting on bones, intestines, and kidneys.

Sequence-defined polypeptide chains form locally ordered secondary structures (i.e., α-helix and β-sheet) through hydrogen bonding between the backbone amides, shaping the overall tertiary structure.
