Is there a typical amino acid profile for whey protein?

[JRRBadBoy4Life]

I noticed most whey proteins don't list the amino acid profile anymore. Anyways, I found this:
Amino Acid Profile:
L-Alanine 1068mg
L-Arginine 601mg
L-Aspartic Acid 2574mg
L-Cystine 314mg
L-Glycine 482mg
L-Glutamic Acid 3815mg
L-Histidine* 493mg
L-Isoleucine (BCAA)* 1044mg
L-Leucine (BCAA)* 2745mg
L-Lysine* 2133mg
L-Methionine* 848mg
L-Phenylalanine 848mg
L-Proline 1047mg
L-Serine 1111mg
L-Threonine 1226mg
L-Tryptophan 627mg
L-Tyrosine 822mg
L-Valine (BCAA) 1070mg

This was for SciFit's Econo Whey. After a quick search this was the only one I could find that still gave an amino acid profile.

After looking at the BCAA's in these two, it would appear to me that it would be just as beneficial and more cost effective to drink one of these as opposed to Xtend or another BCAA product. Thats what Ive been looking for. I think Im going to just stick with whey preworkout.

You're right. But generally the BCAAs found in whey are peptide-bonded, while a stand-alone in a BCAA product they are free-form aminos. Some say that free-form aminos "work better" and "faster" when you need them (pre/post workout). Both are important to take, but at different times.

yeap bcaas and whey are the difference between good and optimal, bcaas are not needed and are only really usefull for that edge once you have your diet training perfected

Don't forget "during workout", which is considered the optimal time to take the free-form BCAA's

I recommend Bulk Leucine powder, ICE, Vendetta, or Xtend.

I think you're slightly confused here: BCAA are indeed bonded but when you take them they need to be digested (cleaved from the bonds) before the body can use them. The three BCAA are part of the nine EAA so just taking the free form EAA will cover both and yes, they'll get into your system quicker because they don't need to be digested first.

I said bonded, not peptide bonded, and this is when in free form (perhaps you should learn to read)!

They are called branched chain amino acids for a reason: it's because they are bonded to side chains with a branch, but having said that, all AA including BCAA are bonded to other AA by peptide bonds to form proteins. Proteins are strings of AA and BCAA bonded together by peptide bonds, just as they are in whey protein.

Also, anyone can google images of BCAA, but it's obvious you don't understand the free form images you see!

I think your 'strong bump' has been deflected, and your 'strong inaccurate' has itself been proven to be inaccurate!

Your qualifications are irrelevant.

This is a 10 year old thread, and the amino acid content of whey protein is basically irrelevant.

Why are my qualifications and the AA content irrelevant?
The AA content is exactly the topic of discussion and my quals in biochemistry are certainly relevant!
The age of the thread is irrelevant, this thread is still out there for people to view and I was commenting to the post by Prez.

lmao please be trolling. of course they have bonds but this is irrelevant. Prez said they are not peptide bonded and you said he was confused and they are indeed bonded. Plz go /thread

You have this so wrong.

Prez said they ARE peptide bonded in whey protein. (it’s in the second sentence beginning “But generally”), do I really need to point that out to you??!! Now you say Prez said they are not peptide bonded. Nowhere in Prez’s post (that I replied to) are the words “they are not peptide bonded”.
See the quote below:

"You're right. But generally the BCAAs found in whey are peptide-bonded, while a stand-alone in a BCAA product they are free-form aminos. Some say that free-form aminos "work better" and "faster" when you need them (pre/post workout). Both are important to take, but at different times.”

To which I replied:

“I think you're slightly confused here: BCAA are indeed bonded but when you take them they need to be digested (cleaved from the bonds) before the body can use them. The three BCAA are part of the nine EAA so just taking the free form EAA will cover both and yes, they'll get into your system quicker because they don't need to be digested first.”

Meaning the peptide bonds within the protein doesn’t need to be digested to release the BCAA because they have been taken in free form and therefore have no peptide bonds. THE CONFUSION was taking both; if you take free form EAA then you are covering both because the three BCAA are part of the nine EAA, so you do not need to take BOTH BCAA and EAA.

You then replied with images of free form BCAA and implied I was inaccurate because there was not a peptide bond in sight. Of course there wasn't because they were free form images, PMSL, and I never said free form were peptide bonded; I pointed that out to you by saying “I said bonded not peptide bonded”, because even in free form they are bonded to branched side chains.

There was absolutely nothing wrong with my first post in reply to Prez.

You either misunderstood what I first posted and you are now just squirming around or you are just twisting things purposely to be argumentative.

Either way; if your whole argument and the cause of the laughter you are experiencing so much that you speak of is based on me saying they were peptide bonded to Prez’s post that they wern’t peptide bonded, then I reiterate, learn to read!

I could digest the posts further to make it easier for you to understand but I can’t be bothered and I now grow very very tired of this conversation, I think you just need to grow up and stop being argumentative!!
