Enzymes
are proteins Bio catalyze.Its has huge life cell .The cell is the
basic structural and functional unit of all known living organisms. It
is the smallest unit of life that is classified as a living thing, and
is often called the building block of life.Some organisms, such as most
bacteria, are unicellular (consist of a single cell). Other organisms,
such as humans, are multicellular. (Humans have an estimated 100
trillion or 1014 cells; a typical cell size is 10 µm; a
typical cell mass is 1 nanogram.)
The largest known cell is an
unfertilized ostrich egg cell.In enzymatic reactions, the molecules at
the beginning of the process are called substrates, and the enzyme
converts them into different molecules, called the products. Almost all
processes in a biological cell need enzymes to occur at significant
rates. Since enzymes are 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.
As
all catalysts, enzymes do not alter the position of the chemical
equilibrium of the reaction. Usually, in the presence of an enzyme, the
reaction runs in the same direction as it would without the enzyme, just
more quickly. However, in the absence of the enzyme, other possible
uncatalyzed, “spontaneous” reactions might lead to different products,
because in those conditions this different product is formed faster.
Furthermore,
enzymes can couple two or more reactions, so that a thermodynamically
favorable reaction can be used to “drive” a thermodynamically
unfavorable one. For example, the hydrolysis of ATP is often used to
drive other chemical reactions.
Enzymes
catalyze the forward and backward reactions equally. They do not alter
the equilibrium itself, but only the speed at which it is reached. For
example, carbonic anhydrase catalyzes its reaction in either direction
depending on the concentration of its reactants.
(in tissues; high CO2 concentration)
(in lungs; low CO2 concentration)
Nevertheless, if the equilibrium is greatly displaced in one direction, that is, in a very exergonic reaction, the reaction is effectively
irreversible. Under these conditions the enzyme will, in fact, only
catalyze the reaction in the thermodynamically allowed direction.
Enzyme Wash Finishes for Denim:
Enzyme
wash is more popular in present world textile industries. Enzymes are
bio chemical substances that are have as catalysts toward specific
reactions. What makes very interesting the enzymes under a chemicals
point of view is their high specificity or in other words, their ability
to attack selectively on to a substrate

- To remove the size material from the garments.
- To remove the starch present on the garments.
- For soft feeling to wear the garments.
- To increase the color fastness and rubbing fastness.
- Especially develop the “Bio-polishing’’ affect cotton/Denim.
- Enzyme improves the anti-pilling properties.
- Enzyme attacks more the surface of the fabrics and gives a very smooth surface.
