		Enzymes can couple two or more reactions, so that a thermodynamically favourable reaction can be used to "drive" a thermodynamically unfavorable one.
		Enzymes are essential to living organisms, and a malfunction of even a single enzyme out of approximately 2,000 present in our bodies can lead to severe or lethal illness.
		Enzymes are also used in everyday products such as washing detergents, where they speed up chemical reactions involved in cleaning the clothes (for example, breaking down blood stains).

	Xylanase improve the digestibility of high wheat finisher diets
		This improvement was linear for the three levels of enzyme tested (0, 4, and 7 IU/g feed), with an improvement in digestibility of 0.37±0.09% for energy and 0.22±0.08% for energy per unit of enzyme per gram of feed.
		Indeed, when expressing the enzyme response as a decrease in indigestibility, a response was observed that was statistically the same for all parameters and much more uniform numerically (see Figure 1).
		Reducing indigestibility with enzymes is intuitively more appropriate than improving digestibility, but it may be a reason why others have failed to show effects of enzymes.

	Body Rewards Digestion Formula
		Enzymes are complex proteins that are produced by living cells and initiate or catalyze specific biochemical reactions in the body.
		The enzyme activity is not based on the amount of enzyme present, (which might be listed in milligram amounts) but rather how fast the enzyme breaks down the substrate (fuel) within the given parameters of the test method, such as pH or temperature (its environment).
		Lipases are enzymes activated by bile salts from the pancreas that break down fat during the digestion process.† Fat digestion begins in the second portion of the small intestine with the action of the pancreatic lipases.
