BIOELEMENTS - 35BB

BioELEMENTs

• Molecule = two or more atoms of the same or different elements that are bonded through interactions from its most external electronic layer

• Element = substance that can't be separated in more simple substances
• An element si made of an atom

Let's remember

- chemical elements that are present in all living matter - 99% of cells mass

What are bioelements?

- living matter = 70-isolated or forming molecules

Characterized by forming covalent bonds and originate functional groups

Indispensable to form biomolecules95% of the mass of a living beingsCarbon (C), hydrogen(H), oxygen (O), nitrogen (N), sulfur (S) y phosphorus (P)

PRIMARY BIOELEMENTS

Secondary bioelements: responsible of the functioning of living beings. It represents 4% of the total mass of the cell

A little ammount of this elements is enough for the development of the body, the lack or a higher concentration of these can harm the organisms

Chemical elements that form 1% of the cells' mass

TRACE BIOELEMENTS (TERTIARY)

Research the main functions of primary, secondary and trace bioelements in life
