Module 5 Assignment: Fats (Lipids)
1. Steven is an IT manager who spends much of his day sitting at his computer. When he is home with his family, he enjoys watching his children play soccer and swim but rarely finds time to exercise himself. Steven’s doctor recently told him that his blood cholesterol levels are elevated. His blood lipids and other information about his medical history are given below:
Sex: Male Age: 37 Family history: Mother had a heart attack at age 60 Height/weight: 5’9”/165 lbs Blood pressure: 145/80 (optimal is less than 120/80 Smoker: Yes Activity level: Sedentary Blood values: Total cholesterol: 210 mg LDL cholesterol: 160 mg HDL cholesterol: 34 mg Triglycerides 120 mg

What are lipoproteins? Define four different types of lipoproteins. Why are lipoproteins needed to transport lipids?
Lipoproteins transport fats (lipids) through the blood stream and lymph
4 types of lipoproteins:
Chylomicron – small milky substance that transports lipids from the mucosal cells of the small intestine, and through the bloodstream, to the body’s cells. When meals high in fat are consumed it makes chylomicrons work harder to grab lipids so the blood looks milky-like.
VLDL - “very low density lipoproteins” has the responsibility to transport lipids out of the liver and to the body’s cells. It contains a high amount of triglycerides so the more VLDLs than the more triglycerides in triglycerides in the blood, increasing the risk of artery disease.
LDL – “low density lipoproteins” transports cholesterol to the arteries walls. High levels of these cholesterol carrying LDLs in the blood increases heart disease.
HDL – extracts cholesterol from the body then transports it to the liver.
Lipoproteins has two components, a lipid and protein. The lipid component is insoluble in water so it will not roam freely in the bloodstream while the protein component is synthesized in the liver and
