Verified step by step guidance

Understand the role of organic molecules in the body: Organic molecules are essential for building and maintaining the structure and function of living organisms. They are primarily composed of carbon, hydrogen, oxygen, and other elements.

Identify the major types of organic molecules: Proteins, lipids, carbohydrates, and nucleic acids are the four major classes of organic molecules that contribute to the structural and functional materials of the body.

Explain the structural role of proteins: Proteins are composed of amino acids and are responsible for forming structures such as muscles, skin, and connective tissues. They also play roles in enzymatic activity and cellular signaling.

Describe the structural role of lipids: Lipids, including fats and phospholipids, are key components of cell membranes and provide insulation and energy storage. Phospholipids form the bilayer structure of cell membranes, which is critical for maintaining cellular integrity.

Discuss the roles of carbohydrates and nucleic acids: Carbohydrates provide structural support in certain tissues (e.g., glycoproteins in connective tissue) and serve as energy sources. Nucleic acids, such as DNA and RNA, are responsible for storing and transmitting genetic information, which indirectly supports the synthesis of structural proteins.
