French fries primarily contain carbohydrates (starch), which is a macromolecule that provides energy when broken down into glucose. They also contain some amount of fats/oils, which are another macromolecule that provides energy and important nutrients like essential fatty acids. Additionally, there can be some small amounts of proteins in the form of plant-based proteins from the potatoes themselves.
The three main elements found in macromolecules are carbon, hydrogen, and oxygen. These elements are essential for building the complex structures of biological macromolecules like proteins, carbohydrates, and lipids. Additional elements like nitrogen, sulfur, and phosphorus can also be present in certain macromolecules.
Degradation of macromolecules refers to the breakdown of large biological molecules, such as proteins, nucleic acids, and carbohydrates, into smaller components. This process is essential for recycling building blocks and providing energy for the cell. Degradation can occur through enzymatic reactions, such as proteolysis or glycolysis.
The biggest fast food company in the world is McDonald's. It has the largest number of restaurants globally and is well known for its iconic golden arches and menu items like Big Macs and french fries.
Carbohydrates, proteins, and fats are macromolecules found in various foods. Carbohydrates are found in foods like bread, rice, and fruits, proteins in foods like meat, dairy, and legumes, and fats in foods like oils, nuts, and avocados.
Proteins are the primary macromolecules that can act as enzymes. They catalyze biochemical reactions by lowering the activation energy needed for the reaction to occur. Other macromolecules like RNA can also exhibit enzymatic activity, known as ribozymes.
