• Proteins function in movement, structure, transport, nutrition, defense, regulation, and more.
• Proteins are large, complex molecules composed of many smaller molecules called amino acids.
• There are 20 amino acids which have the same amino group (-NH2) and carboxyl group (COOH), but different side chain group (represented by R).
• Essential amino acids are not naturally produced by the body and are obtained through consumption of foods rich in protein.
• Non-essential amino acids are naturally produced by the body.
