- Four elements are common to all living things: carbon (C), hydrogen (H), oxygen (O), and nitrogen (N). These four elements alone make up approximately 96% of all living matter. Sulfur (S), phosphorus (P), calcium (Ca), potassium (K), and a few other elements constitute the other 4% of an organism’s mass.

Apr 12, 2023 · Living organisms contain relatively large amounts of oxygen, carbon, hydrogen, nitrogen, and sulfur (these five elements are known as the bulk elements), along with sodium, magnesium, potassium, calcium, chlorine, and phosphorus (these six elements are known as macrominerals).
Oct 19, 2024 · The basic constituents of life are also the most common elements in the universe: carbon, oxygen, hydrogen, nitrogen. Many biochemists therefore regard the emergence of life as inevitable wherever the right chemical and environmental conditions exist.

Scientists believe that about 25 of the known elements are essential to life. Just four of these – carbon (C), oxygen (O), hydrogen (H) and nitrogen (N) – make up about 96% of the human body. These four elements are found in the basic structure of all biochemical molecules. For example, glucose is a carbohydrate and its molecular formula is C6H12O6...
Although many of the elements are required in only very small amounts, they do play a very important role in keeping the body working effectively: 1. Much of the 3–4 grams of iron in the body is found in haemoglobin, the substance responsible for carrying oxygen from the lungs to the rest of the body. 2. The body has about 75 mg of copper, about on...
Large amounts of essential elements can prove toxic: 1. Too much copper in the diet can result in damage to the liver, discolouration of the skin and hair, and can cause hyperactivity in children. 2. Too much iron in the diet can result in damage to the heart and liver. Too little of any given essential element can result in ill health and, if left...
Feb 27, 2019 · The first step toward life involves a fundamental question we can answer: Where did the elements of life come from? Take a look at the simplified periodic table below. See the six elements in green? Those are called the biogenic elements. Image Credit: Periodic Table by David W. Deamer. Used with permission.
