Oats & whey protein powder

[Pseudonym]

In hindsight it appears many people don't know what a microfraction is anyway

I think that's probably very true - in fact, you could go a step further with "virtually everyone except the 3 posters above"...

So for the rest of us unenlightened folk, could someone explain about microfractions and just what denaturing actually does? I understand that protein is made up of amino acids, but that's about the extent of my knowledge.
