When a supplement seller advertises one protein as "anabolic", and another as "anti-catabolic", what does that really mean?
Usually, whey and other fast-digesting proteins are said to be "anabolic", while slow-digesting casein is said to be "anti-catabolic".
Is that all there is to it? "Anabolic" means flooding your bloodstream with aminos quickly, and "anti-catabolic" releases them as a trickle to keep blood aminos from dropping below a certain level?
So what about "bio-available"? Does that really mean anything, or is it just a buzzword? Easily digested? Pre-digested? Other than the balance between different aminos, and how quickly a protein digests, isn't protein just protein?
I suppose peptides may have something to do with it. I don't know much about them yet.

anabolic means to be in a muscle building state, catabolic is to be in a muscle wasting state. you said it yourself about the kinds of proteins. whey is fast acting but tapers of quick(about 2hrs) soy and casein are slow digesting proteins(4-6 hrs). bio-availability means how much protein in what your ingesting your body will use. whey is about 94%, soy protein(supro soy) is close to 100%, beef and chicken are around 60 something%. all proteins have different %'s. hope that helps.

All proteins will make you anabolic. Slow-digesting proteins, like casein (milk), are referred to as anti-catabolic because they take much longer to digest, thus, preventing catabolism. Fast-digesting proteins, like whey, will, like all others, make you anabolic but will lead to catabolism rather quickly, in about 90mins. All the fancy words are just advertising lingo to make their products sound more effective.
In a nutshell, use fast-digesting whey first thing in the morning and post-wo; use slow-digesting casein before bed and in-between meals.
%s refer to how much protein is in a serving compared to fats, and carbs (sugars). The higher the percentage of protein, the lower the fat and carbs.
Bio-availability means how much of the protein your body will likely use. In essence, how much will be utilized effectively. Again, the higher the number, the better.

Anabolic in this sense refers to a a condition, which I cannot remember, (blank), which basically is a massive influx of aminos in the blood.
Anti-catabolic proteins don't produce this 'high' influx, and are released more steadily. HOWEVER, some studies have shown that 60g of casein as opposed to 30g lead to this influx and high levels of aminos as well.
