What Are Enzymes?
• Most enzymes are
Proteins (tertiary
and quaternary
structures)
• Act as Catalyst to
accelerates a
reaction
• Not permanently
changed in the
process
5. 5
Enzymes
• Are specific for
what they will
catalyze
• Are Reusable
• End in –ase
-Sucrase
-Lactase
-Maltase
6. Why Are Enzymes So Important?
Why are we
devoting one whole
lecture topic to a
protein molecule?
Nearly all chemical
reactions in
biological cells need
enzymes to make
the reaction occur
fast enough to
support life.
8. The Enzyme Substrate complex
• When enzymes function
the active site interacts
with the substrate.
• The active site shape
matches the substrates
shape.
• Once the substrate and
active site meet a
change in shape of the
active site causes a
stress that changes the
substrate and produces
an end product.
9. Industrial Uses Of Enzymes
1. Starch conversions
• Production of glucose syrup
• Production of high fructose corn syrup
• Production of high maltose conversion syrups
• Production of cyclodextrins
• Production of ethanol
2. Lignocellulosic Biomass conversions
• Cellulose conversion
• Hemicellulose conversion
• Lignin conversion

14.Enzyme-Replacement Therapy
11. • Doctors measure the amount and type of an enzyme
to determine any diseases
Ex. Damaged liver
Diagnosing
12. Enzyme Capsules
• Suggested for people over 35 years of age
• Plant-based enzymes are preferred over
animal derived enzymes
• Many different kinds of capsules
• Take once with every meal
