Question 2

Lipids

Answer 2

lipids are the chemical group name for organic substances of a fatty nature

Question 3

Glycerides

Answer 3

chemical group name for fats. fats are formed from a glycerol base with one, two, or three fatty acids attached .

Question 4

glycolipid

Answer 4

a lipid with a carbohydrate attached

Question 5

hyperlipidemia

Answer 5

high lipid levels in the blood

Question 6

fatty acids

Answer 6

fatty acids are the major structural components of fats

Question 7

saturated

Answer 7

the state of being filled. saturated fats are filled with all there available carbon bonds with hydrogen making the fat solid at room temp. generally from animal sources

Question 8

linoleic acid

Answer 8

essential fatty acid that consists of 18 carbon atoms and 2 double bonds. an omega 6 fatty acid, found in vegetable oils

Question 9

alpha linoleic acid

Answer 9

esstential fatty acid with with 18 carbon bonds and 3 double bonds. an omega 3 fatty acid. found in soybean, canola, and flaxseed oil.

Question 10

cholesterol

Answer 10

a fat related compound called a sterol that is synthesized only in animal tissues. Primarily synthesized in the Liver.

Question 11

lecithin

Answer 11

phospholipid produced by the liver is a key building block of cell membranes as a component of the lipid bilayer. It is hydrophilic (water loving) and is used for transporting fats and cholesterol throughout the body

Question 12

lipoproteins

Answer 12

major vehicles for lipid transport in the bloodstream, are combinations of triglycerides, protein, phospholipids, cholesterol and other fat soluble substances

Question 13

fat’s fuel

Answer 13

9 cal/gram

Question 14

adipose

Answer 14

tissue throughout the body where fat is stored. fat covers organs to protect them and humans have a layer of fat under skin to keep body temp stable.

Question 15

bile

Answer 15

an emulsifying agent produced by the liver and transported to the gallbladder to concentration and storage.

Question 16

emulsifier

Answer 16

an agent that breaks down large fat globules into smaller, uniformly distributed particles

Question 17

micelles

Answer 17

packages of free fatty acids, monoglycerides and bile salts that travel in the bloodstream for absorption

Question 18

chylomicron

Answer 18

lipoprotein formed in the intestinal cell that is composed of triglycerides, cholesterol, phospholipids, and protein. Chylomicrons allow for the absorption of fat into the lymphatic circulatory system before entering blood circulation

Question 19

adipose

Answer 19

tissue in the body that is the main storage for fats

Question 20

bile

Answer 20

emulsifying agent produced by the liver and transported to the gallbladder for concentration and storage.

Question 21

emulsifier

Answer 21

an agent that breaks down large fat globules into smaller uniformly distrubted particles. Happens in the small intestine by bile acids

Question 22

micelles

Answer 22

packages of free fatty acids, mono glycerides and bile salts

Question 23

chylomicron

Answer 23

a lipo protein formed in the intestinal cell that is composed of triglycerides, cholesterol, phospholipids and protein. chylomicrons allow fat to be absorbed into the lymph system before going into the bloodstream.
