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.
Dimethyl sulfoxide (DMSO) is an organosulfur compound with the formula (CH3) 2 S O.This colorless liquid is an important polar aprotic solvent that dissolves both polar and nonpolar compounds and is miscible in a wide range of organic solvents as well as water.It has a relatively high melting point.he sodium derivative of DMSO formed in this way is referred to as  dimsyl sodium . It is a base, e.g., for the deprotonation of ketones to form sodium enolates, phosphonium salts to form Wittig reagents, and formamidinium salts to form diaminocarbenes.
