Proteins are complex macromolecules made up of amino acids that perform a variety of functions in the body.

• Proteins are made up of long chains of amino acids.

• They are essential for the growth and repair of tissues in the body.

• Proteins also play a role in the immune system, as enzymes, and as hormones.

• Examples of proteins include hemoglobin, insulin, and collagen.

Normality is a measure of concentration used in chemistry to express the number of equivalents of a substance per liter of solution.

• Normality is used to measure the concentration of acids and bases in a solution.

• It is defined as the number of equivalents of a solute per liter of solution.

• Normality is different from molarity, which measures the number of moles of solute per liter of solution.

• For example, a 1N solution of hydrochloric acid contains 1 equivalent of HCl per liter...read more

Distillation is a process of separating components of a mixture based on their boiling points.

• It involves heating the mixture to vaporize the component with the lowest boiling point.

• The vapor is then condensed and collected as a separate liquid.

• This process is commonly used in the production of alcoholic beverages, petroleum refining, and water purification.

• Distillation can also be used to purify chemicals and separate different components of a mixture.

Digestion is the process of breaking down food into smaller molecules that can be absorbed by the body.

• Digestion starts in the mouth with the mechanical and chemical breakdown of food.

• The food then travels through the esophagus to the stomach where it is further broken down by stomach acid and enzymes.

• The small intestine is where most of the nutrients are absorbed into the bloodstream.

• The remaining waste products are then passed through the large intestine and eliminated as f...read more
