Verified step by step guidance

Begin by understanding the role of proteins in the body. Proteins are essential macromolecules that serve as the building blocks for body tissues, including muscles, skin, and organs.

Recognize that proteins are composed of amino acids, which are linked together in specific sequences to form polypeptides. These polypeptides fold into unique three-dimensional structures that determine their function.

Learn that enzymes, which are crucial for catalyzing biochemical reactions, are primarily made of proteins. Enzymes speed up reactions by lowering the activation energy required for the process.

Differentiate proteins from other nutrient classes such as carbohydrates, lipids, and vitamins. Carbohydrates are mainly used for energy, lipids for energy storage and cell membrane structure, and vitamins for various regulatory functions.

Conclude that proteins are the nutrient class primarily used to build body tissues and make enzymes, highlighting their importance in growth, repair, and metabolic processes.
