Chemical Components of a Cell



Question and Answer on Cell Chemicals

Question:

What are the chemical components of a cell?

Answer:

The chemical composition of the cell may vary depending on the cell type, but the essential chemical components present in all cells (animals and plants) are carbon, hydrogen, oxygen, nitrogen, phosphate and sulfur (the latter two in smaller amounts). These components correspond to approximately 98% of the cell.

These and other components, present in smaller quantities, are part of the inorganic and organic compounds that are used by the cell.

The inorganic components present in the cell are: water and minerals. The organic ones are: glycids, lipids, proteins, vitamins and nucleic acids.

Between 75% and 85% of a cell is made up of water. Proteins are between 10% and 15. Lipids are around 3%. Glycerides correspond to 1%, as do nucleic acids.

Cell: Water is the chemical element present in the largest amount.
