can peptides be absorbed or only amino acids? What about fats? Is there a role for esther and such like?
CHO are always monomeres such as glucose, fructose and galactose when they are absorbed right?
But what about proteins, they will be amino acids, but what about polypeptides or peptides (for instance some proteins are in hydrolysat shapes)
What about fats? Can phospolipids be absorbed or only FA's?
This is surely an interesting question. I have previously found that brain lipoamidase can hydrolyze lipoylamide (but not biotinylamide), peptides, and esters (please see file; Multiple hydrolase LIP). Brain lipoamidase also can hydrolyze anchor-portion of the anchored membrane proteins (please see file; Release of anchored).
Thank you very much for your kind recommendation. Enzyme seems to recognize total chemical structure and hydrophobicity.
Some di and tri-peptides can be absorbed directly but the general trend is that the intestines degrade them to amino acids before they get absorbed.
