Answer:

phospholipid (FOS-foe-LIP-id) Question 2: the chief form of fat in the diet and the major storage form of fat in the body; composed of a molecule of glycerol with three fatty acids attached; also called triacylglycerols (try-ay-seel-GLISS-er-ols).

Answer:

triglycerides (try-GLISS-er-rides) Question 3: on the near side of; refers to a chemical configuration in which the hydrogen atoms are located on the same side of a double bond.

Answer:

cis

Question 4: a general term for all diseases of the heart and blood vessels. Atherosclerosis is the main cause of CVD. When the arteries that carry blood to the heart muscle become blocked, the heart suffers damage known as coronary heart disease (CHD).

Answer:

cardiovascular disease (CVD) Question 5: an alcohol composed of a three-carbon chain, which can serve as the backbone for a triglyceride.

Answer:

glycerol (GLISS-er-ol) Question 6: tiny spherical complexes of emulsified fat that arise during digestion; most contain bile salts and the products of lipid digestion, including fatty acids, monoglycerides, and cholesterol.

Answer:

micelles (MY-cells) Question 7: one of the phospholipids. Both nature and the food industry use lecithin as an emulsifier to combine water-soluble and fat-soluble ingredients that do not ordinarily mix, such as water and oil.

Answer:

lecithin (LESS-uh-thin)

Question 8: results of blood tests that reveal a person'various lipoproteins.

Answer:

blood lipid profile Question 9: compounds containing a four-ring carbon structure with any of a variety of side chains attached.

Answer:

sterols (STARE-ols or STEER-ols) Question 10: fatty acids needed by the body but not made by it in amounts sufficient to meet physiological needs.

Answer:

essential fatty acids

Question 11: an accumulation of fatty deposits, smooth muscle cells, and fibrous connective tissue that develops in the artery walls in atherosclerosis. Plaque associated with atherosclerosis is known as atheromatous (ATH-er-OH-ma-tus) plaque.

Answer:

plaque (PLACK) Question 12: a synthetic fat made from sucrose and fatty acids that provides 0 kcalories per gram; also known as sucrose polyester.

Answer:

olestra Question 13: an omega-6 polyunsaturated fatty acid with 20 carbons and four double bonds; present in small amounts in meat and other animal products and synthesized in the body from linoleic acid.

Answer:

arachidonic acid (a-RACK-ih-DON-ic) Question 14: The fatty acid that is necessary for the synthesis of eicosapentaenoic and

docosahexaenoic acids is:

Answer:

C)linolenic acid.Question 15: one of the sterols containing a four-ring carbon structure with a carbon side chain.

Answer:

cholesterol (koh-LESS-ter-ol) Question 16: the double bond of a fatty acid, where hydrogen atoms can easily be added to the structure.

Answer:

point of unsaturation

Question 17: lipids that are solid at room temperature (77°F or 25°C).

Answer:

fats

Question 18: clusters of lipids associated with proteins that serve as transport vehicles for lipids in the lymph and blood.

Answer:

lipoproteins (LIP-oh-PRO-teenz) Question 19: an omega-3 polyunsaturated fatty acid with 22 carbons and six double bonds; present in fatty fish and synthesized in limited amounts in the body from linolenic acid.

Answer:

docosahexaenoic acid (DHA) (DOE-cossa-HEXA-ee-NO-ick) Question 20: a family of compounds that includes triglycerides, phospholipids, and sterols.Lipids are characterized by their insolubility in water. (Lipids also include the fat-soluble vitamins.)

Answer:

lipids Question 21: the type of lipoprotein made primarily by liver cells to transport lipids to various tissues in the body; composed primarily of triglycerides.

Answer:

VLDL (very-low-density lipoprotein) Question 22: a nitrogen-containing compound found in foods and made in the body from the amino acid methionine. Choline is part of the phospholipid lecithin and the neurotransmitter acetylcholine.

Answer:

choline (KOH-leen) Question 23: an enzyme that hydrolyzes triglycerides passing by in the bloodstream and directs their parts into the cells, where they can be metabolized for energy or reassembled for storage.

Answer:

lipoprotein lipase (LPL) Question 24: the type of lipoprotein derived from very-low-density lipoproteins (VLDL) as VLDL triglycerides are removed and broken down; composed primarily of cholesterol.

Answer:

LDL (low-density lipoprotein)
