Stars form inside relatively dense concentrations of interstellar gas and dust known as molecular clouds. These regions are extremely cold (temperature about 10 to 20K, just above absolute zero). At these temperatures, gases become molecular meaning that atoms bind together.
Histamine intolerance is due to a (temporary) deficiency or an inhibition of the enzyme diamine oxidase (DAO). DAO is the enzyme responsible for the degradation of histamine.Although DAO is virtually found in the whole body, the bowels constitute its most important site of action.he histamine intolerance test measures the activity of the DAO contained in the blood, since the DAO circulates through the body in the blood. The blood is mixed with a substance similar to histamine and the degradation of this substance is measured.
Inhibition of succinic acid dehydronase. 1  1. ENZYME â¢ Enzymes are protein catalysts that accelerate the rates of biochemical reactions and regulate metabolic pathways. 2  2. 3  3. Succinate dehydrogenase ïµ Only makes the trans-fumarate. 4  4. DIFFERENT REACTION OCCUR IN THE CYTOPLASM and we are going to study complex II. 5  5. 6  6. 7  7. 8  8. 9  9. 10  10. 11  11. 12  12. 13  13. 14  14. 15  15 The malonate ions therefore block the active site-but remember that this is reversible. 2  The malonate ions will break away and free up the enzyme again. 3  The malonate ions are in competition for the site-they aren't destroying it.
