Matching Type. Match column A from Column B. Write your answer on space provided Transcribed Image Text: Lipids – are commonly known as the storing energy for later use. They are found in hormones
and membrane component of the cellI. Lipids have different structural types such as carboxylic acid or
fatty acids, triglycerides or neutral fats, steroids and waxes. Naturally occurring esters are lipids that
contain one or more long chain carboxylic acids called fatty acids. These are insoluble in water but
soluble in nonpolar solvents. The most abundant of the lipids are the fats and oils, also called
triglycerides. Fats are solid at room temperature and contain saturated fatty acids, which are basically
produced by animals. Animal fats include the lard and the butter. Oils are liquid at room temperature and
contain unsaturated fatty acids. Most oils, such as vegetable oils, corn oil, palm oil, olive oils are
produced by plants. If you eat in moderation, fats are good sources of body fuel. They are considered
good emergency food and are efficient energy storage system. However, an excessive quantity of fats
intake is not good for the heart. The reasons why fats are not good for the heart is because they tend to
clog arteries and overwork the heart. Steroids are another class of lipids and the most important steroid
is cholesterol. It is a sterol because of the presence of alcohol or the hydroxyl functional group. It is
found mainly in animal cells and small amount of this may also found in the plant cell. Refer to the

STRUCTURE OF CHOLESTEROL
Cholesterol plays as important role in eukaryotes and especially abundant in cell membrane of
animal cells. Small amount of cholesterol can also be found in the membrane of some organelles inside
the cells, such as the mitochondria and the endoplasmic reticulum. It is also found in the nerve cells,
myelin, covers nerve axons to conduct the electrical impulse that make movement, sensation,
thinking, learning, and remembering possible. Animals are able to use cholesterol to synthesize other
steroids like cortisone, testosterone and estrogen which are essential for the process of reproduction.
Although cholesterol is essential lipid for human, excessive levels of cholesterol in the blood can lead to
deposits in the arteries of the heart. These arterial deposits are a leading cause of heart disease. Transcribed Image Text: Column A
