Outline the importance of essential amino acids in the diet of a human. (4 marks)

Essential for Protein Synthesis: Essential amino acids are crucial for protein synthesis. Our body uses them to build new proteins, which are needed for the creation and maintenance of body tissues such as muscles, skin, and hair.

Supports Immune Function: Essential amino acids play a vital role in supporting the immune system. They are involved in the production of antibodies, which are proteins that help the body fight off infections and diseases.

Promotes Healthy Metabolism: Essential amino acids are necessary for a healthy metabolism. They help the body break down food and convert it into energy. They also assist in the production of enzymes, which are proteins that speed up chemical reactions in the body.

Cannot be Produced by the Body: Unlike non-essential amino acids, essential amino acids cannot be produced by the body and must be obtained through the diet. This makes it crucial to consume foods that are rich in essential amino acids to ensure the body functions properly.
