Lipids or fats are insoluble in water. Things that do not dissolve in water are generally termed lipophilic.
Steroids are a type of lipid, which is a group of macromolecules that are hydrophobic and primarily composed of hydrocarbons.
The macromolecules that are composed primarily of C, H, and O are lipids and carbohydrates.
Living organisms are primarily composed of four types of macromolecules: carbohydrates, proteins, lipids, and nucleic acids. Carbohydrates provide energy and structural support, proteins perform a variety of functions including catalyzing reactions and providing structure, lipids store energy and form cell membranes, and nucleic acids (DNA and RNA) store and transmit genetic information. These macromolecules work together to enable the complex processes necessary for life.
Nonpolar macromolecules found in cell membranes primarily include lipids, such as phospholipids and cholesterol. These molecules form the lipid bilayer, which acts as a barrier to ions and polar molecules, preventing them from freely entering or exiting the cell. The hydrophobic (water-repelling) nature of these nonpolar regions restricts the passage of charged particles, thereby helping to maintain the cell's internal environment. This selective permeability is crucial for cellular function and homeostasis.
Soybeans are primarily made up of macromolecules called proteins, carbohydrates (such as starch and fiber), and fats. These macromolecules provide essential nutrients and energy for human consumption.

A synonym for leprosy is "Hansen's disease." This term is named after the Norwegian physician Gerhard Armauer Hansen, who discovered the bacterium responsible for the disease. Leprosy primarily affects the skin, nerves, and mucous membranes.
Reese's contain primarily carbohydrates (sugars), fats (in the form of peanut butter and cocoa butter), and proteins (in the form of peanut butter). The dominant macromolecules in Reese's are carbohydrates and fats.
The organelles of a cell are primarily composed of lipids, proteins, and nucleic acids. Lipids are important for forming membranes, proteins provide structure and function, and nucleic acids store genetic information. Carbohydrates are also present in some organelles as storage molecules or for structural support.
Fatty acids consist of long hydrocarbon chains with a carboxyl group at one end, which distinguishes them from the basic units of other macromolecules like carbohydrates, proteins, and nucleic acids. For example, while fatty acids are primarily hydrophobic and serve as energy storage and structural components in membranes, carbohydrates are made of sugar units (monosaccharides) that are hydrophilic and primarily function as energy sources. This structural difference underlies their distinct roles in biological systems.
Cell membranes are composed primarily of phospholipids. These phospholipids form a lipid bilayer that acts as a barrier to the passage of most molecules. Additionally, cell membranes also contain proteins, cholesterol, and carbohydrates.
The electrons in an atom are primarily responsible for chemical reactions.
