Answer:
Molecules of life refer to the various chemical compounds that are essential for the existence and functioning of living organisms. These molecules include carbohydrates, lipids, nucleic acids, and proteins.
Carbohydrates are a group of compounds made up of carbon, hydrogen, and oxygen atoms. They serve as a primary source of energy for living organisms and are found in foods such as sugars, starches, and fibers. Lipids are a diverse group of compounds that are insoluble in water but soluble in nonpolar solvents. They include fats, waxes, and oils and are important for energy storage and cell membrane structure.
Nucleic acids, such as DNA and RNA, store and transmit genetic information. DNA, or deoxyribonucleic acid, is the genetic material that carries the instructions for the development and function of all living organisms. RNA, or ribonucleic acid, helps to translate the genetic information stored in DNA into proteins.
Proteins are large, complex molecules made up of smaller units called amino acids. They play many important roles in the body, including structural support, enzyme function, and cell signaling. Proteins are also responsible for the regulation of metabolic processes, movement, and the immune response.
In summary, molecules of life are the essential chemical compounds that are vital for the existence and functioning of living organisms. They include carbohydrates, lipids, nucleic acids, and proteins, which play diverse roles in the body such as energy storage, genetic information storage and transmission, structural support and cell signaling.
