Proteins are essential macronutrients that play a crucial role in various bodily functions, including muscle repair, enzyme production, and immune responses. Understanding what constitutes a complete protein is fundamental to optimizing dietary choices. ### Amino Acids: The Building Blocks Proteins are composed of smaller units known as amino acids. There are 20 amino acids in total, each contributing to different functions within the body. Amino acids link together in various sequences to form proteins, which are then utilized by the body for growth and repair. ### Essential vs. Non-Essential Amino Acids Amino acids are categorized as either essential or non-essential. The body can synthesize non-essential amino acids, but essential amino acids must be obtained from the diet. A complete protein source contains all nine essential amino acids in adequate proportions, which is crucial for maintaining optimal health. ## Is Quinoa a Complete Protein?
