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.
Multivitamins nutrition facts label showing that the international unit of, for example, vitamins D and E correspond to different gram values. 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.
See Weight for detail of mass/weight distinction and conversion. Avoirdupois is a system of mass based on a pound of 16 ounces, while Troy weight is the system of mass where 12 troy ounces equals one troy pound. The symbol g 0 is used to denote standard gravity in order to avoid confusion with the (upright) g symbol for gram.
Iu agrees: “Peanut butter takes the lead with 7 to 8 grams of protein per serving, which makes it a great option for fueling workouts.” Winner: Peanut butter Fat and cholesterol
International units (IU) are based on measured biological activity or effect, or for some substances, a specified equivalent mass. [citation needed] Enzyme activity is commonly used for e.g. liver function tests like AST, ALT, LD and γ-GT in Sweden. [5]
“The fiber content should be at least 3 to 4 grams of fiber per slice,” says Laura Iu, ... “Aim for options with at least 3 grams of protein per slice, lower sodium, and minimal added sugars ...
One can convert this definition to the number of international enzyme units (IU, enzyme activity that produces 1 μmole of product per minute) per gram of grain, for example. Maltose, the main sugar produced in mashing, is a disaccharide of glucose with one reducing equivalent (one reactive aldehyde group).
