Oh no no no
no the use of dextrose is most certainly NOT necessary to "sythesize" protein. In fact, it has been shown that the use of dextrose may not even be ideal for promoting anabolism.
"The macronutrient composition of a protein meal effects where that protein is ultimately deposited and incorporated into new proteins. This is due mainly to the effects of insulin on amino acid uptake in tissues that will either deaminate and/or retain that protein well before your muscles ever see it. Such tissues include the gastrointestinal tract (stomach, small and large intestines, and the splanchnic bed (liver), then into the periphery which include ALL organs and tissues of the body, not just muscle tissue.
It turns out the insulin causes fewer amino acids to make it past these first pass organs/tissues. Why? Because as I said, those tissues will take up a greater percentage of those amino acids and use them for their own purposes or deaminate them.
A model based on the collected tracer data demonstrates the effects of carbs on the partitioning of ingested proteins. (note the difference between fast and slow proteins as well)
Milk protein
Splanchnic proteins 18%
Peripheral proteins 34%
Sucrose and milk protein
Splanchnic proteins 35%
Peripheral proteins 26%
Sucrose and soy protein
Splanchnic proteins 37%
Peripheral proteins 19%

Regardless of that, you don't need it by any means. If it does help, it's nothing to nitpick over. The major factor is still taking in excess calories to promote growth, so to worry about dextrose, well...that's stupid.
