Wonderful World of Proteins

By: Madison Jones, Anthony Palm, & Michael Vance

What are Proteins?

Proteins are large molecules composed of one or more long chains of amino acids and are essential part of all living organisms, especially as structural components of body tissues.

Why are proteins essential for life?

Proteins are essential for building muscle mass, cell formation, tissue maintenance and repair, controlling chemical reactions, and are a great source of energy.

How do proteins relate to real life?

  • The human body has about 100,000 different types of proteins
  • High protein diets can help you lose weight
  • Proteins are the building blocks of your body
  • Proteins help fight off everyday infections or disease
  • Proteins help people stay in shape

Types of Proteins

  • Enzymes- Speed up chemical reactions in cells, Luciferase
  • Structural Protein- Regulate body tissues and organs, Collagen
  • Signaling Protein- Send messages around the body and to the brain, Adrenalin
  • Regulatory Protein- Controlling the interaction of myosin and actin, HOX (tells tissues what organs to form)
  • Transport Protein- Move ions in and out of the cell, hemoglobin, cytochrome
  • Sensory Protein- Opsin (in the eye converts light so it can be interpreted by the brain)
  • Motor Protein- Convert chemical energy into mechanical work, myosin, dynein, and kinesin.
  • Defense Protein- antibodies, fibrin forms blood clots
  • Storage Proteins- casein stores proteinin milk
