Enzyme Activity Units Conversion

[Guest guest]

Is there a link where I can find conversions for the different enzyme

activity units?

I compiled a list of a all the conversions I could find. If you have

the Enzymes for Autism book, it is on page 320-321. Otherwise, here

it is below. If you find any more I will add them to the list. .

1 FCC LU = 8.4 LU (units for lipase)

1000 FIP = 10,000 LU (units for lipase)

1 GAL = 2 AGSU (units for alpha-galactose)

10 GDU (gelatin digesting units) = 15 MCU (milk clotting units)

30 DU = 1 AG (units for amylase)

100 BTU = 1,956,522 FCC PU (units for protease)

100 HU = 88 HUT (units for protease)

160 SU = more than 20 IAU (units for sucrase)

chymotrypsin 1 mg = 1000 USP units

trypsin 1 mg – 25,000 USP units

papain 1 mg = 6000 USP units

The U.S. Pharmacopeia (USP) helped by establishing a standard for the

pancreatic enzymes (animal-derived) by which you can compare other

enzyme supplements, such as plant- and microbial-derived. This

standard is called `X' and each X contains an equivalent of:

25 USP units of amylase

2 USP units of lipase

25 USP units of proteolytic enzymes

If a supplement contains 5X pancreatic enzymes, it would provide five

times the amount of each of the enzymes in this standard, or 125 USP

amylase, 10 USP lipase, and 125 USP protease. There is no direct

conversion between USP units and FCC units because they are produced

from different sources, using different methods.

Thanks !!!!

I'm comparing Kirkman's Enzyme Complete and Houston Nutriceuticals 's Zyme

Prime. (We're very happy with the HNI's Zyme Prime, but there is a Canadian

distributor for Kirkmans, which means less border crossing issues). Kirkman

lists the units for Amylase as MWU, while HNI gives DU. How are these

converted?

I couldn't find a conversion right off. It isn't that common a

measure. Maybe Devin can help here. I will try to call one of the

enzyme manufacturers tomorrow if I get home early enough. Here is

what it stands for:

===================

One Modified Wohlgemuth Unit (MWU) is that activity which will

hydrolyze one (1) milligram of soluble starch to a defined size

dextrin in thirty (30) minutes under the conditions of the assay.

===================

These units are usually not that interchangeable because they measure

certain activity under 1 set of conditions: a defined pH, substrates,

temp, processing, etc. So use the activities for general guidelines

and then go with whatever works best for you. These assays are not

exact stomach/intestine measurements.

If you have ever seen the labels that list a protease with 4

different units at various pHs, this is one enzyme measured with 4

different tests. It is not meant to ADD all the measures together.

That can look tricky on a label if you aren't reading it closely.
