Enzymes and Digestion

Pepsin is the enzyme produced in the stomach that is responsible for protein digestion.
Optimal pH for pepsin activity is around 1.5 to 2, which creates an acidic environment for effective protein breakdown.

Protein Subunits

Proteins are composed of amino acids, which are the basic building blocks of proteins.
There are 20 different amino acids that combine in various sequences to form proteins.

Carbohydrate Subunits

Carbohydrates are made up of monosaccharides, the simplest form of carbohydrates.
Common monosaccharides include glucose, fructose, and galactose.

Fat Subunits

Fats, or lipids, are primarily composed of fatty acids and glycerol.
Triglycerides, the most common type of fat, consist of three fatty acids bonded to one glycerol molecule.

Synthesis of Macromolecules

Polymerization is the process that forms large molecules (macromolecules) from smaller building blocks like amino acids, monosaccharides, and fatty acids.

Experiment Observations

In the "Digestion of Protein" experiment, the biuret reagent turns purple when proteins are digested, indicating the presence of peptides or amino acids.
