MACROMOLECULES

CARBOHYDRATES

• These molecules are made mainly of sugars.
• Monosaccharides are the subunits of carbohydrates.
• The names of Carbohydrates usually end with use.
• Carbohydrates are primary sources of energy for cells.

CHEMICAL COMPOSITION

• A carbohydrate's carbon and oxygen are equal, while the Hydrogen is twice
• As much as the Carbon and Oxygen.

FUNCTION

• Carbohydrates provide energy and structural support.

CHITIN

PROTEINS

• The subunits of proteins are amino acids.
• Amino acids are bonded together through peptide bonds.
• Proteins are also known as polypeptides.
• Proteins make up over half of an organisms dry weight.
• Proteins carry out many of a cell's numerous functions.

CHEMICAL COMPOSITION

• The chemical composition of proteins is formed when a chain of amino
• acids are formed.

FUNCTION

• Serve as enzymatic catalysts.
• Carry out numerous function of cells that involve energy.

LIPIDS

• Most lipid molecules are hydrophobic.
• Lipids are also saturated and unsaturated fats.
• Phospholipids make up the outside of the cell membrane and regulate
• what enters and leaves the cell.

CHEMICAL COMPOSITION

• Lipids are composed of hydrocarbon molecules.
• They are composed of fatty acid tails and 3 carbon glycerol (alcohol)
• molecules.

FUNCTION

• The function of lipids is to store heat, or energy, for long amounts of time.

FATS

WAXES

OILS

NUCLEIC ACIDS

• The monomers of nucleic acids are nucleotides.
• Nucleic contain genetic for the organism.
• Examples of nucleic acids are DNA or RNA.

CHEMICAL COMPOSITION

• Nucleic acids have 5 carbon sugar present in the monomers.

FUNCTION

• The function of nucleic acids is to contain the genetic material of an organism.
