BIOELEMENTS AND THEIR PERCENTAGES

The elements which are used in formation of various chemical compounds from which living organisms are made are called Bio-elements.

Out of 92 naturally occurring chemical compounds, only 16 are found to be bio-elements and out of these 16 only 6 account for 99% of the total mass in human body.

PERCENTAGES OF BIO-ELEMENTS BY MASS OF A HUMAN BEING:

  • Oxygen                                                              65%
  • Carbon                                                               18%
  • Hydrogen                                                           10%
  • Nitrogen                                                               3%
  • Calcium                                                                2%
  • Phosphorous                                                        1%
  • Potassium                                                       0.35%
  • Sulphur                                                           0.25%
  • Chlorine                                                          0.15%
  • Sodium                                                            0.15%
  • Magnesium                                                     0.05%
  • Iron                                                                0.004%
Some elements like Copper, Manganese, Zinc and iodine are present in Traces.
