Hydrogen

H, atomic number 1. Most abundant element in the body by atom count; essential constituent of water (H₂O), all organic molecules, and hydrogen bonds stabilising DNA and protein secondary structure. H⁺ (proton) gradient across the inner mitochondrial membrane drives ATP synthesis.

Also known as: H, ¹H, protium, deuterium, H⁺, hydrogen bond donor
