Lipids

​What is a lipid?

• Lipids are made of 3 fatty acids and 1 glycerol

• Examples include: Waxes, natural oils, phospholipids, steroids, fats, etc.

​Fun Fact: No true monomers or polymers!

Lipids

​What do lipids do?

• Store long-term energy

• Make up biological membranes and waterproof coverings

​Fun Fact: No true monomers or polymers!

Multiple Choice

The monomer of a lipid is...

• Trick question! They don't have true monomers

• fatty acids

• amino acids

Multiple Select

What do lipids do? (Select TWO answers)

• Make up biological membranes

• Store short-term energy

• Store long-term energy

• Store genetic information

Carbohydrates

​What are carbohydrates?

• Made of Carbon, Hydrogen, and Oxygen.

• The monomers are monosaccharides, which are sugars. The polymers are polysaccharides, which are starches.

• Sugars end in -ose. Example: Glucose, Lactose, Fructose, Galactose

​Fun Fact: End in -ose

Carbohydrates

​What do carbohydrates do?

• Carbohydrates are the main source of energy and are used for short-term energy.

• Examples include: Glucose, fructose, lactose, galactose, sugar, starchs (like pasta, potatoes, etc)

​Fun Fact: End in -ose

Fill in the Blank

Carbohydrates are made of _______.

Multiple Choice

What do carbohydrates do?

• Store short-term energy

• Control rate of chemical reactions

• Store genetic information

• Store long-term energy

Proteins

​What are proteins?

• Made of Carbon, Hydrogen, Oxygen, and Nitrogen.

• The monomers are amino acids. The polymers are proteins or polypeptide chains.

• Examples Include: Enzymes, muscles, meat, beans, soy, nuts, peanut butter, etc

​Fun Fact: One of the most important biomolecules! Nitrogen makes it different

Proteins

​What do proteins do?

• Control rate of chemical reactions through enzymes.

• The names of enzymes end in -ase. Example: Lactase, lipase, protease

• Make up bones and muscles.

• Transport materials in and out of cells.

​Fun Fact: Enzymes end in -ase

Fill in the Blank

The monomers of proteins are....

Multiple Choice

What do proteins do?

• All of these

Nucleic Acids

​What are Nucleic Acids?

• Made of Carbon, Hydrogen, Oxygen, Nitrogen, and Phosphorus

• The monomers are nucleotides. These are: Adenine, Thymine, Cytosine, and Guanine.

​Fun Fact: Phosphorus makes it different

Nucleic Acids

​What do Nucleic Acids do?

• Store and transmit genetic information

• The polymers are called DNA (deoxyribonucleic acid) and RNA (riboneucleic acid).

​Fun Fact: Phosphorus makes it different

Fill in the Blank
