Hydrogen
Essential for water composition and involved in various biochemical reactions including acting as a proton donor in redox reactions.
Carbon
Backbone of all organic molecules, allows for the formation of complex macromolecules necessary for life.
Nitrogen
Major component of amino acids, nucleotides, and hence, proteins and DNA.
Oxygen
Involved in cellular respiration and is required for efficient energy production in aerobic organisms.
Phosphorus
Critical for energy transfer in cells as part of ATP, constituents of nucleic acids and phospholipids.
Sulfur
Important for protein structure through the formation of disulfide bonds and is present in some vitamins and cofactors.
Sodium
Key for maintaining the electrochemical gradient across cell membranes, important in nerve impulse transmission.
Potassium
Essential for maintaining intracellular fluid volume, also important in nerve signal transmission and muscle contraction.
Calcium
Critical for muscle contraction, nerve impulse transmission, and blood clotting; also a key component in bone and teeth structure.
Iron
Integral part of hemoglobin and myoglobin for oxygen transport in the blood and muscles; also involved in electron transport chain.
