What is the significance of high 3-methyl-histidine in my blood first time 2.3..Second time 5.3 says normal is 0-0...I have burning muscles....

What is the significance of high 3-methyl-histidine in my blood first time 2.3..Second time 5.3 says normal is 0-0...I have burning muscles....

Did you exercise: If elevated, the individual is breaking down muscle. When i see this, i ask my patient if he exercised heavily the day before having their blood drawn. Muscle breakdown is a natural result of exercise. If the individual did not exercise, and 3-methylhistidine is elevated, he is breaking down muscle. He may be protein deficient, in which case the individual begins to break down. ...Read more

What factors modify enzyme structure and function?

What factors modify enzyme structure and function?

Quite a lot: Enzymes are under a wide variety of controls. Plain chemistry: they speed reactions. If the stuff to do the reaction (substrate) arent' there, it don't go. Rate changes with temperature, concentration of reactants, etc. Regulation. Negative feedback . generally the end result inhibits enzyme further activity. Not always. Regulators small compounds ..cyclic GMP, cyclic AMP often are regulators. ...Read more
