BACTERIA CAN BE ELIMINATED IN MANY WAYS

Soap, Heat, Alcohol, and Denaturing Proteins

SOAP AND WATER Does a good job of getting rid of dirt,

grease, and grime off of your body. It doesn’t however destroy bacteria.

ALCOHOL AND HEAT Denaturing or destroying bacteria

chemically is the only way to really fight germs.

There are two easy ways to destroy bacteria and denature there proteins for sure Alcohol Heat

DENATURING PROTEINS Much of bacteria's vital parts and

structure are made of protein chains. If the structure of these proteins is

destroyed the cell cannot survive. When the structure of these proteins is

destroyed it is called denaturing.

BEFORE DENATURING Protein structure is specific and helical

before denaturing. The structure, if you could see it, would

look much like a stretched out slinky. It looks like this because some

molecules in the protein are scared of water (hydrophobic), and others love water (hydrophilic).

AFTER DENATURING The structure of the protein is

destroyed and is no longer specific. After being denatured it would

resemble something like a pile of yarn or string.

ALCOHOL Alcohol causes proteins to be

denatured by breaking relatively weak hydrogen bonds.

Breaking these hydrogen bonds causes the molecules that make up each protein chain to be scattered randomly causing the proteins to lose structure.

Alcohol is in gel and sanitizers like Purell.

HEAT Heat also breaks hydrogen bonds. Heat causes the molecules that like

and the molecules that don’t like water to be scattered.

Organized randomly because they want to be either dry or wet.

This causes water and air to be trapped in the proteins, called coagulation.

A Fried egg is a good example.
