Nov 3, 2023 · Over 99% of a human cell is made up of just five elements: carbon, hydrogen, oxygen, nitrogen, and phosphorus. That same elemental mix exists, with minor variations, in every other living thing on Earth.
- Carbon. Carbon's ubiquitous nature on Earth and beyond lies in its ability to form different types of chemical bonds: single, double and triple. With this property, carbon can join with a wide range of other elements.
- Hydrogen. Hydrogen, the lightest and simplest chemical element, can form only one type of bond – a single bond. Nevertheless, hydrogen can form a greater variety of compounds than any other element, even carbon.
- Nitrogen. Although nitrogen may get comparatively little attention, it is abundant in nature. More than three-fourths of the Earth's atmosphere consists of nitrogen gas.
- Oxygen. Oxygen is vital for respiration on a moment-to-moment basis. At the same time, it is found in water, all proteins and all foods. Fats, which even the leanest animals possess in significant quantities, include oxygen, which – like carbon – is a wondrously versatile molecule from a chemical standpoint.
Feb 27, 2019 · If you add up all the atoms composing a living cell, those six represent close to 99% of the elemental composition of proteins, nucleic acids, and cell membranes. Life does need these six elements, but it only works if the elements have combined into molecules.
At its most fundamental level, life is made up of matter. Matter is any substance that occupies space and has mass. Elements are unique forms of matter with specific chemical and physical properties that cannot be broken down into smaller substances by ordinary chemical reactions.
