Primary Bioelements

The most abundant elements in living organisms, making up 99% of living matter. These are the building blocks of organic molecules.

Secondary Bioelements

Elements less abundant than primary ones, but still crucial for functions like bone health and nerve signals.

Trace Elements

Elements found in tiny amounts, but essential for enzyme function, oxygen transport and hormones.

Carbon (C)

A vital primary bioelement, the backbone of most organic molecules crucial for life.

Study Notes

Bioelementos

  • Bioelementos primarios: These are the most abundant elements in living things, making up 99% of living matter. They include carbon (C), hydrogen (H), oxygen (O), nitrogen (N), phosphorus (P), and sulfur (S). These elements form the basis of essential organic molecules like carbohydrates, lipids, proteins, and nucleic acids.

Bioelementos secundarios

  • Bioelementos secundarios: Less abundant than primary bioelements, still vital for organism function. They include calcium (Ca), sodium (Na), potassium (K), magnesium (Mg), chlorine (Cl), and iron (Fe). These elements are crucial for bone formation, nerve impulse transmission, and maintaining fluid balance (among other functions).

Oligoelementos

  • Oligoelementos: Present in very small amounts, but essential for proper bodily functions. Examples include copper (Cu), zinc (Zn), manganese (Mn), iodine (I), and cobalt (Co). These elements support enzyme activation, oxygen transport, and hormone production.
