The average 70 kg adult human body is made up of approximately $7 \times 10^{27}$ atoms. While much of this mass is from organic compounds, the question of "are humans made of minerals?" reveals a fundamental truth about our composition: we are a complex combination of both organic and inorganic substances. These essential inorganic minerals play critical roles far beyond just bone structure.

Carbohydrates, such as starches and sugars, are found in a vast array of foods, from whole grains and vegetables to fruits and dairy products. The simplest of these compounds, simple sugars, consist of just three fundamental elements. Understanding which three elements make up starches and sugars is crucial to grasping the basic chemistry of energy production in living organisms.

The human body consists of thousands of different proteins that are vital for virtually every bodily function, yet the fundamental units comprising these complex structures are surprisingly common chemical elements. Understanding which elements make up protein is key to unlocking the mysteries of this essential nutrient.

The vast majority of carbohydrates, from simple sugars like glucose to complex starches, contain only carbon, hydrogen, and oxygen. This standard composition naturally raises the question: can carbs contain nitrogen?

The molecular formula for glucose is C6H12O6, indicating its basic components, but what are the elements that make glucose? This critical monosaccharide, a simple sugar essential for cellular energy, is formed from a trio of common elements arranged in a precise and stable structure.

Carbohydrates are one of the most abundant organic molecules on Earth, essential for all living organisms. The name 'carbohydrate' itself provides a major clue, combining 'carbo-' for carbon and '-hydrate' for water, revealing the very specific and consistent elemental makeup. This fundamental composition is crucial for understanding how these macromolecules function as primary energy sources for the body.

The iron in your blood and the metal in a car began their journey in the fiery heart of an exploding star millions of years ago. But how did that iron get to us? It came from outer space, was mined from Earth, and is found in the foods we eat every day.

Over two-thirds of the human body's adipose tissue is composed of lipids, or fats. This diverse group of macromolecules is universally characterized by its hydrophobic nature, but its elemental makeup varies depending on the specific lipid class. The most fundamental and common elements in lipids are carbon, hydrogen, and oxygen.

According to the American Diabetes Association, carbohydrates are the primary source of energy for the body. To understand their energy-yielding properties and structural functions, we must first examine their chemical makeup. So, which three elements are found in all carbohydrates? The answer is a fundamental concept in biochemistry, forming the very backbone of these essential molecules.

According to scientific consensus, carbohydrates are organic molecules composed of carbon, hydrogen, and oxygen. But a question that often arises in biology and chemistry is: which element is absent in carbohydrates? While composed of three elements, they notably lack another key element found in other life-sustaining molecules.
