According to the mnemonic often used in biology, proteins are classified as CHON, not CHO. This distinction highlights the key difference in their elemental composition, with the inclusion of nitrogen being the defining factor that separates proteins from other common biomolecules like carbohydrates and lipids.

Every living organism depends on proteins for critical functions, and at the core of these complex molecules lies a handful of fundamental chemical building blocks. Proteins are primarily composed of four common elements, with others playing a key role in specific amino acids.

Every living organism relies on proteins to carry out vital functions, with some containing hundreds of thousands of different types. To understand how these complex molecules work, it is fundamental to know what are the elements of the protein, which consist of common foundational atoms and other, less frequent ones.

Over 50% of the dry weight of a cell is protein, highlighting its immense biological importance. Understanding how the elements of a protein differ from a carbohydrate is fundamental to comprehending their unique roles, from providing structural support to supplying energy.

Every protein, one of the most vital macromolecules in all living organisms, is fundamentally built from a core set of chemical elements. While all proteins contain carbon, hydrogen, oxygen, and nitrogen, some also incorporate sulfur and other trace elements. Understanding these fundamental building blocks is key to comprehending how proteins function and assemble within the body.
