Proteins and Enzymes

Proteins and Enzymes

1. Proteins

   • Made up of Carbon, Hydrogen, Oxygen and Nitrogen
   • For growth and repair
   • The basic units of a protein are called amino acids

2. Enzymes

   • These control chemical reactions within the body
   • They are described as biological catalysts
   • Amylase
     • Starch>Maltose
   • Lipase
     • Fats>Fatty Acids + Glycerol
   • Pepsin
     • Protein>Polypeptides
   • Phosphorylase
     • Glucose-1-Phosphate>Starch

3. Catalyst

   • A catalyst is a substance that speeds up reactions
   • A catalyst is unchanged by the reaction
   • A catalyst is often described as a key
