Lipid Worksheet Lipids are fats including oils, waxes, steroids and cholesterol. Lipids are made from a hydrocarbon monomer that links together to form a hydrocarbon chain.

Hydrocarbon

Hydrocarbon Chain

Hydrocarbon chains vary in length and are nonpolar. Nonpolar molecules are hydrophobic, meaning they do not interact or mix with water. The three most common forms of lipids in the human body are triglycerides, phospholipids and cholesterol. Most of the fats you consume are triglycerides. Your body breaks them down and then stores the fats as new triglycerides. Triglycerides are three fatty acids bonded to a glycerol. Fatty acids are a hydrocarbon chain with a carboxyl group connecting it to the glycerol. Glycerol is a three carbon alcohol. There are two types of fatty acids, saturated and unsaturated. Saturated fatty acids are straight and are found mostly in animals. Unsaturated fatty acids are bent because of a double bond and are found mostly in plants. 1) Looking at the fatty acid below, copy it into the two remaining rows.

2) Fatty acids are composed of a carboxyl group and ____________________________. 3) What are the four parts of a triglyceride? _____________ & 3 __________________ 4) The human body stores fats as __________________________. 5) Label the following fatty acids as saturated or unsaturated.

6) When a hydrocarbon chain is bent, it is called _______________________________. Phospholipids are similar to triglycerides except that a phosphate group replaces one of the fatty acids. The phosphate group is a polar molecule. Polar molecules are hydrophilic and interact with water. Phosphate Group

7) Fill in one phosphate group and the remaining fatty acid. Label all the parts.

Phosphate Group

The common form of a phospholipid looks like a circle with two tails. Phospholipids are polar on the phosphate group side and nonpolar on the fatty acid side. When one phospholipid is next to another phospholipid, they line up with the heads on one side and the tails on the other side. Two rows of phospholipids are called a lipid bilayer and they make up the membranes of all cells. Phosphate Group Head Lipid Bilayer Fatty Acid Tails 8) Below, label which parts are polar and nonpolar.

9) Where would you find the lipid bilayer in a cell? _____________________________ Cholesterol has a different shape in that it forms rings instead of hydrocarbon chains. Cholesterol is found only in animals in: body tissues, cell membranes and blood. All steroid hormones (testosterone, estrogen, and progesterone) are derived from cholesterol. 10) What lipid do animal cells have inside their cell membranes? __________________ 11) What does hydrophobic mean? __________________________________________ 12) What are steroid hormones made from? ___________________________________
