Here's a breakdown:
* Major Elements: The six elements you mentioned (oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus) make up about 99% of the body's mass. These elements are crucial for forming the building blocks of life, including water, proteins, carbohydrates, lipids, and nucleic acids.
* Trace Elements: The remaining 25 essential elements are present in much smaller quantities but are equally vital for various bodily functions. These include:
* Sodium, potassium, chloride, magnesium, sulfur: These are involved in maintaining electrolyte balance, nerve function, and muscle contraction.
* Iron, zinc, copper, manganese, selenium, iodine, chromium, molybdenum, cobalt, fluoride, and boron: These play roles in enzyme activity, hormone production, immune function, and bone health.
It's important to note that the complexity of human life arises from the arrangement and interactions of these elements within molecules. These molecules can be incredibly diverse, forming proteins, carbohydrates, lipids, nucleic acids, and countless other compounds that contribute to the intricate processes that keep us alive.
While six elements dominate the body's mass, it's crucial to recognize the significance of the trace elements, as they play vital roles in maintaining our health and well-being.
