Carbs and Lipids Review

What is the primary role of carbs in human bodies?

• As an immediate energy source to power all the functions of life

• As a secondary energy source to use once we get tired

• As a vital structural component in bones, teeth, and nails

• Carbs do not serve a vital role in the human body, more of a secondary role.

Pictured here is one of the vital macromolecules we have discussed. The question is, is this a carbohydrate or a lipid?

Another identification thing Mr. Tindle? You're wild for this one. Now the question is what is the reaction called that results in these simple molecules fusing into a larger molecule?

The name carbohydrate denotes a lot about these molecules, specifically the chemical composition of the molecules. Using what you know, what three elements are found within Carbohydrates?

What is the monomer of Carbohydrates?

• Monosaccharides

• Disaccharides

• Polysaccharides

• Glycerol Heads

• Fatty Acid Tails

What is the monomer of a lipid? *Multiple Answers are expected here.

• Fatty Acids

• Glycerols

• Phospholipids

• Sterols

Lipids are similar in chemical composition to carbohydrates; except one element appears in lipids that does not in carbohydrates, what is that element?

• Phosphorus

• Nitrogen

• Sulfur

• Helium

What are the 3 types of fats we talked about in class; aside from phospholipids. *Multiple Answers are expected here

• Unsaturated Fats

• Saturated Fats

• Trans Fats

• Mega-saturated Fats

More Identification Mr. Tindle? Extra wild for this one chief.

Check out this lovely image of elements connected together. We have only talked about carbs and lipids so far but the question is: Is this molecule a lipid or a carbohydrate?

Monomers are usually joined together by dehydration reactions in order to form more complex macromolecules. However, there is a side effect of this reaction. It releases a common compound that we all need. What is that common compound?

• Water (H20)

• Ammonia (NH3)

• Salt (NaCl)

• Oxygen (O2)
