What are 20 examples of molecules?
Molecules are the building blocks of matter. They are made up of atoms bonded together in specific arrangements. In this article, we will explore 20 examples of molecules that are commonly found in various substances and play important roles in our daily lives.
Water (H2O):
Water is a vital molecule for all life on Earth. It consists of two hydrogen atoms bonded to one oxygen atom. Water exhibits unique properties such as high heat capacity and surface tension, making it essential for many biological and chemical processes.
Glucose (C6H12O6):
Glucose is a simple sugar that acts as an important energy source for living organisms. It plays a key role in cellular respiration, providing ATP – the main energy currency of cells.
Carbon dioxide (CO2):
Carbon dioxide is a greenhouse gas responsible for global warming. It is a waste product of cellular respiration in animals and a byproduct of burning fossil fuels. Plants, on the other hand, use carbon dioxide in photosynthesis to produce glucose and oxygen.
Chlorophyll (C55H72O5N4Mg):
Chlorophyll is the green pigment found in plants and is responsible for capturing sunlight during photosynthesis. It plays a crucial role in converting light energy into chemical energy.
Adenosine triphosphate (ATP):
ATP is the universal energy molecule in all living organisms. It carries energy within cells for various metabolic processes. ATP is composed of adenine, ribose, and three phosphate groups.
DNA (Deoxyribonucleic acid):
DNA is the hereditary material found in almost all living organisms. It stores genetic information and is responsible for inheritance. DNA is a double helix structure composed of nucleotides containing sugar, phosphate, and nitrogenous bases (adenine, thymine, cytosine, and guanine).
Alcohol (C2H6O):
Alcohol is an organic molecule known as ethanol. It is commonly used in beverages, such as beer and wine. Alcohol has psychoactive effects on the central nervous system.
Aspirin (C9H8O4):
Aspirin is a non-steroidal anti-inflammatory drug (NSAID) used to relieve pain, reduce inflammation, and lower fever. It works by inhibiting the synthesis of prostaglandins, which are responsible for pain and inflammation.
Caffeine (C8H10N4O2):
Caffeine is a naturally occurring stimulant found in coffee, tea, and chocolate. It acts as a central nervous system stimulant, promoting wakefulness and reducing fatigue.
Acetaminophen (C8H9NO2):
Acetaminophen, also known as paracetamol, is a commonly used over-the-counter pain reliever and fever reducer. It works by inhibiting the synthesis of prostaglandins in the central nervous system.
Nitrogen gas (N2):
Nitrogen gas is an essential component of the Earth''s atmosphere, making up about 78% of its composition. It is inert, non-toxic, and plays a crucial role in various biological processes.
Oxygen gas (O2):
Oxygen gas is required for the process of respiration in most living organisms. It plays a vital role in converting glucose into ATP, providing energy for the body''s activities.
Glucose-fructose (C12H22O11):
Glucose-fructose, also known as table sugar or sucrose, is a disaccharide composed of glucose and fructose. It is commonly used as a sweetener in various food products.
Ibuprofen (C13H18O2):
Ibuprofen is a non-steroidal anti-inflammatory drug (NSAID) used to relieve pain, reduce inflammation, and lower fever. It works by inhibiting the synthesis of prostaglandins, similar to aspirin.
Ethylene (C2H4):
Ethylene is a gaseous plant hormone that plays a significant role in fruit ripening. It is also used in agriculture to control the growth and development of plants.
Benzene (C6H6):
Benzene is an aromatic hydrocarbon that is widely used in the production of plastics, detergents, and other chemicals. It is an important industrial solvent as well.
Acetic acid (CH3COOH):
Acetic acid is the main component of vinegar and is widely used in the food industry as a preservative and flavoring agent. It is also used in the production of plastics and solvents.
Sodium chloride (NaCl):
Sodium chloride, commonly known as table salt, is an ionic compound made up of sodium and chloride ions. It is essential for maintaining fluid balance, nerve function, and muscle contraction in the human body.
Ammonia (NH3):
Ammonia is a compound made up of nitrogen and hydrogen atoms. It is used in cleaning products, refrigeration, and the production of fertilizers. Ammonia is also produced by living organisms as a waste product.
Vitamin C (C6H8O6):
Vitamin C, also known as ascorbic acid, is an essential nutrient for humans. It acts as an antioxidant, supports the immune system, aids in collagen synthesis, and helps with wound healing.
