Chapter 5 Flashcards
Triglycerides, phospholipids, and sterols are the 3 main types of
Fats
Where in the body are the majority of triglycerides stored for future needs
Adipose
Cholesterol is needed for which of the following functions
Sex hormones, cell membrane functions
Most___are digested in the small intestine with the help of bile and pancreatic lipase
Triglycerides
Produced by salivary gland digests short and medium chain fatty acids in milk; inactivated by stomach acid
Produced by gastric glands; breaks down some fats into smaller units
Produced pancreas; breakdown triglycerides into monoglycerides
Produced by cells of the intestinal wall; signals the gall bladder to release bile
Lingiunial lipase
Gastric lipase
Pancreatic lipase
Cholecystokinin
The body stores lipids as
Triglycerides
A triglyceride is compromised of
Three fatty acids and one glycerol
A fatty acid with a 10 carbon and one double carbon bond is
Monosaturated medium chain fatty acid
A fatty acid made up of 16 carbon chain with no double carbon bond is called
Saturated long chain fatty acid
Essential fatty acids and precursors needed to produce which type of biological compounds
Eicosanoinds
The two essential fatty acids are
Linoleic and linolenic acid
Which of the following foods is rich in omega-3 fatty acids
Salmon
The vast majority of fat digestion and absorption occurs in the
Small intestine
HDL our name because of their high proportion of
Protein
Lipids are more energy dense when compared to carbs. How many calories do fats and oils contain
9 calories
Have no double bonds; found in animal products; solid at room temperature
Have one double bond; high levels in olive oil and avocados; liquid at room temperature
Have more than one double bond; essential for the body; found in corn flower and sunflower oil: liquid at room temperature
Saturated fatty acids
Mono saturated fatty acid
Polysaturated fatty acids
Helps transport triglycerides, cholesterol and fat soluble vitamins from small intestine and lipids from the liver
VLDL
Delivers cholesterol to the cells, if the amount in the bloodstream exceeds the amount that can be used by the cells, the result is high blood levels that can build upon the walls of blood vessels
LDL
Takes cholesterol from other Lipo proteins or body cells due to most cells not breaking down the cholesterol and so is returned to the liver for elimination
HDL
Major lipid producing organ
Hormone secreted by adipose tissue that targets the brain and produces feelings of satiety
Cells that stores triglycerides
The addition of hydrogen atoms to unsaturated fatty acids. Often creates trans fatty acids
Fats that must be supplied by the diet and can be used to make other fatty acids
Liver
Leptin
Adipocyte
Hydrogenation
Essential fatty acids
