Protein - SS1 Biology Lesson Note

Proteins are essential macronutrients in nutrition that play a crucial role in building and repairing tissues, supporting growth and development, and maintaining overall health. Composed of amino acids, proteins are found in a variety of animal and plant-based foods. They serve as the building blocks for muscles, bones, skin, hair, and organs, while also acting as enzymes, hormones, and antibodies.

Proteins are involved in numerous biological processes, including transportation of nutrients and molecules, immune function, and energy production. Meeting the body's protein requirements through a well-balanced diet is important for optimal health and function.
