Does hard boiling an egg change it's properties at all?would boiled egg whites be just as good as normal egg whites as far as protien intake?.

Yes, you can absorb more nutrients when it is hard boiled in comparison to raw eggs.

Do the macro's change at all for whites and yolk,it seems like one of the most convienient foods to me,just boil a couple dozen up stick em in the fridge and you have yourself a nice alternative protien source for the week(peeling them aside)of course.

I donīt think macros change a significant amount but there is a protein that is only avaiable when the egg is hard boiled.

Is this true? Not doubting you, just never heard that.

Albumen in the urine is a general sign, as studies show that a significantly higher amount of malabsorbed protein (egg) was found in the urine of healthy individuals (1). Stable isotope techniques are used to determine the digestibility of raw eggs vs. cooked eggs. In another study, using this method, it was demonstrated that the assimilation of cooked egg protein is efficient, albeit incomplete, and that the true ileal digestibility of egg protein is significantly enhanced by heat-pretreatment (2). Heat-pretreatment of course being cooked.
Not to mention you have a 1 in 30,000 chance to get salmonella from a raw egg. Also, if you blend raw eggs or whatever, you can break up the chemical bonds of amino acids where as cooking them can hook the bonds together, which inevitably is the objective.

Yes, the digestibility of albumen is way higher in hard boiled eggs.

Then is that a faster absorbing protien also?

Eggs are still a complete protein before you cook them (they have all the essential amino acids) but the folding of the protein will be changed by cooking - and this change makes the protein change shape so your body is better able to digest it.

As for changes in speed of digestion... ... It could probably be assumed that, as the folding increases the digestability, it would likely increase the speed at which the protein could be broken down... But I would not be able to tell you for certain.

I can tell you that whole eggs will digest slower than the whites alone - simply because of the fats present in the yolk which will delay gastric emptying...

Yes...whites are a much faster absorbing protein. Many people if not able to consume whey post w/o they will have egg whites b/c of the rate in which it digests. By adding the yolks or other fats you will slow the digestion down though.
