In pharmacology, the international unit (IU) is a unit of measurement for the effect or biological activity of a substance, for the purpose of easier comparison across similar forms of substances. International units are used to quantify vitamins and biologics ( hormones , some medications , vaccines , blood products and similar biologically ...
The enzyme unit, or international unit for enzyme (symbol U, sometimes also IU) is a unit of enzyme's catalytic activity. [ 1 ] 1 U (μmol/min) is defined as the amount of the enzyme that catalyzes the conversion of one micro mole of substrate per minute under the specified conditions of the assay method .
The insulin unit conversion is not consistent with his molar weight 5808 Da (g/mol): Using the insulin unit definition as 0.0347 mg/IU and human insulin molar mass 5808 g/mol: 1 IU = (0.0347*10^-3 g) / (5808 g/mol) = 5.974 * 10^-9 mol. But in other sources is written, that 1 IU of insulin is 6.945 * 10^-9 mol. Where is the mistake?
It is more difficult to give an exact equivalence between milligrams (mg) and FCC units, but 125 mg should be sufficient as several companies list it as equal to 1750 FCC units. -- Quest out of UK shows 2000 ALU per 200mg tablet of Lactase enzyme.
In the metric system, a microgram or microgramme is a unit of mass equal to one millionth (1 × 10 −6) of a gram.The unit symbol is μg according to the International System of Units (SI); the recommended symbol in the United States and United Kingdom when communicating medical information is mcg.

One international unit of insulin (1 IU) is defined as the "biological equivalent" of 34.7 μg pure crystalline insulin. [citation needed] The first definition of a unit of insulin was the amount required to induce hypoglycemia in a rabbit. This was set by James Collip at the University of Toronto in 1922. Of course, this was dependent on the ...
An equianalgesic chart is a conversion chart that lists equivalent doses of analgesics (drugs used to relieve pain). Equianalgesic charts are used for calculation of an equivalent dose (a dose which would offer an equal amount of analgesia) between different analgesics. [1]
