MACROMOLECULES

what is a macromolecule?

a macromolecule is a very large molecule, made up of smaller units linked together

The Four Major Macromolecules

Carbohydrates

Carbohydrates are our main source of energy, make up the cell wall in plants(cellulose), carbs are energy!

elements of carbohydrates

• Carbon
• Hydrogen
• Oxygen

there are 2 types of Carbohydrates

• Simple
• Complex

Carbs are made up of 1 or 2 monomers, the most common being sugar/glucose

Carbohydrates are a large group of organic compounds, and help you make energy.

examples of Carbohydrates

• Noodles
• pasta
• pizza
• bread

what are protiens

proteins make you because DNA is made of proteins, and DNA makes you

where are proteins found?

• plants 
• foods
• grains and nuts
• fruits and vegetables

proteins are also found in beef, chicken, pork, and fish

what is the monomer of proteins

• amino acids
• long chains of monomers

proteins are composed of one or more amino acids and are of a class of nitrogenous

elements of proteins

• carbon
• hydrogen
• oxygen
• nitrogen
• and sometimes sulfur

examples of proteins

• amino acids
• fibrous
• globular
• membranes

protein functions are
structural support, defense against germs and involved in bodily movement

What are Lipids?

what do lipids do?

• store energy
• insulate
• cushion
• and lots of other stuff

where are lipids found

• they are found in plant seeds
• in fat and connective tissue of animals
• located in the phospholipid bi-layer of cell membraines

examples of lipids

• fats
• steroids
• waxes
• vitamins

Untitled Slide

• carbon
• hydrogen
• oxygen

lipids are fatty acids or their derivatives and float in water

the monomer of lipids
are triglycerides

nucleic acids

nucleic acids are complex substance present in living cells especially DNA or RNA

nucleic acids
contain genetic information, and the code for
all the protein in your body

nucleotides are the monomers of nucleic acids

what elements make up nucleic acids

• nitrogen
• phosphate
• five carbon sugars

examples of nucleic acid are DNA and RNA
