Enzyme
Chemical substance that while remaining unchanged, helps a chemical reaction to take place. At the end of this reaction, the enzyme can help in other reactions of the same kind. Protein in the body that initiate and accelerate chemical reactions. Digestive enzymes act in the mouth, stomach, and intestines to break down food into simpler compounds usable for producing energy or for building various body substances. In case of enzyme deficiency, digestive enzymes, unlike other kinds, can readily be used by the body when provided by an external source. Alfalfa, Apple, Artichoke (leaves and root), Barley (malt), Carline thistle, Cascara sagrada (bark), Castor bean (oil), Dandelion (root), Papaya, Peppermint, Soybeans, Wood sorrel, Yellow bedstraw, all contain Enzymes

ENZYME
A cellular protein whose shape allows it to hold together several other molecules in close proximity to each other. In this way, enzymes are able to induce chemical reactions in other substances with little expenditure of energy and without being changed themselves. Basically, an enzyme acts as a catalyst.

enzyme
Protein or protein-based molecules that speed up chemical reactions occurring in living things. Enzymes act as catalysts for a single reaction, converting a specific set of reactants (called substrates ) into specific products. Without enzymes life as we know it would be impossible.

ENZYME
Any of numerous proteins or conjugated proteins produced by living organisms and functioning as biochemical catalysts. Specifically, an organic catalyst that accelerates (catalyzes) specific transformations of material in plants and animals. Enzymes are elaborated by cells, but their action is independent of life processes and they are not consumed in the course of their action. They occur in all tissues, particularly in digestive secretions, and are of greatest importance for the cellular processes or the digestion and utilization of food.

Enzyme
Enzymes are proteins that catalyze (i.e. accelerate) chemical reactions. In enzymatic reactions, the molecules at the beginning of the process are called substrates, and the enzyme converts them into different molecules, the products. Almost all processes in a biological cell need enzymes in order to occur at significant rates. Since enzymes are extremely selective for their substrates and speed up only a few reactions from among many possibilities, the set of enzymes made in a cell determines which metabolic pathways occur in that cell.
