The band-sharpening effect relies on the fact that negatively charged glycinate ions (in the electrophoresis buffer) have a lower electrophoretic mobility than do the protein–SDS complexes, which, in turn, have lower mobility than the chloride ions (Cl − ) of the loading buffer and the stacking gel buffer. 

[Cl−] > [protein–SDS] > [glycinate].

RS Configuration 

Atoms of higher atomic number rank above those of lower atomic number (e.g., —OH ranks above —CH3). If the first substituent atoms are identical, the priority is established by the next atom outward from the chiral center (e.g., —CH2OH takes precedence over —CH3).

Regulate body temperature

Body temp remain constant

Heat (in) = heat (out)

Heat (in) = Metabolism + solar radiation

Heat (out) = Radiation + Convection + Conduction + Evaporate
