Phase And Vertical Shift. Phase and vertical shift refer to the transfer of a function in the horizontal and vertical directions, respectively. For the function , where A, B, C, and D are constants, the phase shift is defined as C/B. If the phase shift is positive, the shift occurs to the left; if the phase shift is negative, the shift occurs to the right.
So it is possible that a whole food meal will have a different impact on the duration of protein synthesis than pure amino acids. Our lab has recently shown that the duration of protein synthesis in response to a complete meal containing protein, carbohydrates, and fats is approximately 3 hours long. Therefore, it appears that a complete meal slightly prolongs the duration of protein synthesis.
The size of a synthesized protein can be measured by the number of amino acids it contains and by its total molecular mass, which is normally reported in units of daltons (synonymous with atomic mass units), or the derivative unit kilodalton (kDa). Yeast proteins are on average 466 amino acids long and 53 kDa in mass.
