Proteins, carbohydrates, and lipids are all macronutrients essential for our diet. They provide energy for the body and are important for various functions such as cell structure, hormone production, and energy storage. Additionally, they are all composed of carbon, hydrogen, and oxygen atoms.
Carbohydrates: Polysaccharides Proteins: Polypeptides Lipids: Triglycerides Nucleic acids: Polynucleotides
Macromolecules are very large molecules. The term is used for the four biopolymers nucleic acids, proteins, carbohydrates and lipids. It is also used to describe non-polymeric molecules - such as macrocycles.
The four main classes of macromolecules are carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates are sugars and their polymers, lipids are fats, oils, and membranes, proteins are made up of amino acids and play crucial roles in cells, and nucleic acids store and transmit genetic information.
Nitrogen is primarily found in proteins, which are made up of amino acids that contain nitrogen. Carbohydrates and lipids typically do not contain nitrogen in their structure.
Enzymes are proteins that catalyze chemical reactions in biological systems. Carbohydrates, lipids, nucleic acids, and proteins are biological macromolecules that serve various roles in the body: carbohydrates provide energy, lipids store energy and form cell membranes, nucleic acids carry genetic information, and proteins have structural, catalytic, and regulatory functions.
