Important Elements in Organisms What are the most commonly occuring elements in the human body?
Goals for the day! ➔ By the end of class, you will make predictions about the six most common elements in organisms. ➔ Today you will share in collaborative groups about the six most common elements.
What’s an element? ➔ An element is something basic and important––in chemistry, an element is one of the essential molecules that everything else is made of. ➔ Examples of element include: __________________.
Biomolecules ➔ All living organisms are made of essential elements. ➔ We call these compounds biomolecules. All of these biomolecules are organic, which means that they contain carbon. ◆Carbon has four valence electrons, which means this element forms strong covalent bonds with many other elements.
Biomolecules ➔ All of our biomolecules are classified into four groups: ◆Carbohydrates (quick and short term energy) ◆Lipids (long term energy) ◆Proteins (building and work) ◆Nucleic Acids (genetic information) ➔ Each of these classes have different structures and functions.
Carbohydrates (15%) Carbohydrates are made up of carbon, hydrogen and oxygen (CHO). ➔ Examples include: Cellulose provides structure in plants; glucose (_____) is a accessible source of cellular energy for both plants and animals. ➔
Lipids (10%) Lipids are made up of carbon, hydrogen and oxygen. ➔ Fats are an accessible fuel source; phospholipids also make up cellular membranes. ➔
Proteins (50%) All proteins contain carbon, hydrogen, oxygen and nitrogen. ➔ Enzymes carry out almost all the chemical reactions that take place in cells. ➔
Nucleic Acids (18%) Nucleic acids contain carbon, hydrogen, oxygen, nitrogen, and phosphorus. ➔ DNA stores life's genetic code. ➔
