Nu hittade jag det jag letade efter om protein:
Important Characteristics of Proteins
It's the amino acids in the protein we eat that are the true nutrients, not the protein itself.
There are about 20 different amino acids (20 different R gruops) that occur naturally in proteins.
Each protein has a specific arrangement of amino acids. So when we talk about a specific protein (i.e. human insulin) the sequence of amino acids in that protein will always be the same, regardless of what person't insulin we are referring to. We sometimes refer to this as the "Rule of Specificity." In other words, the arrangement of amino acids for each protein is specific for each species. Therefore, human insulin will always have the same exact amino acid structure within the human species but the structure or sequence of amino acids in chicken insulin may be different from human insulin.
Amino acids in a protien are not interchangeable. Your body cannot replace one amino acid for another. We refer to this as the "Rule of Non-replacement." It kind of relates back to the Rule of Specificity. In a very basic example, if your cells are trying to make some kind of skin protein which has the amino acid sequence A-B-C-C-D-A-F-G... and for some reason your cells don't have any amino acids "G", your cells cannot take amino acid "H" and put it in G's place. If there is no amino acid "G" available in the cells, that skin protein will not be synthesized.
The type of body protein is not influenced by the type of protein eaten. This is because proteins eaten are digested to amino acids. For example, if your major dietary source of protein is fish, you won't turn into a fish! However, the amount of protein eaten influences the amount of protein in the body). If you don't eat enough protein (regardless of the type of protein eaten) your cells won't be able to make proteins because there won't be any amino acids to make them with!
Most proteins contain all of these 20 amino acids (corn zein is an exception with only different 19 amino acids in it).
There is essentially no tissue storage of surplus protein (maybe a little in the circulation for a couple of hours after eating).
Some amino acids are essential (they are true nutrients). Remember, a true nutrient is one that cannot be synthesized in enough quantity by the body to meet our needs and therefore it MUST be supplied in the diet.
Notera näst sista punkten: Kroppen har inga proteindepåer så det är livsviktigt att varje dag (varje mål?) få i sig tillräckligt med protein.
Sen hjälper det inte att äta en massa extra protein eftersom kroppen inte kan tillgodogöra sig mer än 50-70 g protein per dag (om jag fattat rätt). 30 g per måltid vill jag minnas att jag sett nån siffra på.
Sen kan det ju vara intressant att veta att det går åt energi för att kroppen skall kunna ta upp protein, det är alltså en energikrävande process.
om bananer och jägarsnus så det kanske är snabba kolhydrater du vill åt...
