Lipids Flashcards
What is a fat
Compounds that are soluble in solvents but insoluble in water
Where are fatty acids found
Adipose tissue
Skeletal muscle
Use of fatty acids
To release energy into the human body
Food examples
Meat
Butter
Cheese
Chocolate
Oil
What elements make up fatty acids
Carbon
Hydrogen
oxygen
What is the typical structure of lipids
Ch3
What is the typical structure of lipids
Ch3
What is the general formula
R-COOH
What is COOH
Carboxylic acid
What is COOH
Carboxylic acid
What is CH3
Methyl end
Where is the methyl end
Start of chain
Where is COOH END
Where is COOH END
What are the classifications of lipids
Short chain fatty acid = 6 chain or less
Medium chain fatty acid = 8 - 12
Long chain fatty acid = 14 chain +
Very long chain fatty acid = 22 chains +
What are the 2 essential fatty acids
Omega 3
Omega 6
Example of omega 3
example of omega 6
the steps of lipid metabolism
lipolysis
fatty acid transport
carnitine shuttle
where does lipid metabolism first take place
in adipose tissue
what happens in the adipose tissue
lipolysis
triglyceride is broken unto fatty acid and glycerol
after being broken down in the adipose cell where is glycerol and fatty acid released into
blood stream
what is the key regulating enzyme
hormone sensitive lipase
what up regulates HSL
adrenaline
what down regulates HSL
insulin
what is the role of HSL
breakdown triglyceride
what do fatty acids bind to in the blood
albumin
why do fatty acids bind to albumin
carry fatty acid to skeletal muscle
where does glycerol go
into liver cell
what happens to the gycerol in the liver cell
glycerol is turned into glucose
where is this glucose released to after being in the liver
blood then muscle
what is the role of the carnitine shuttle
fatty acid from cytoplasm to mitochondria matrix
what binds to fatty acid in the cytoplasm
carnitine
what happens in the matrix of mitochondria
beta oxidation
what is the ratio of the carnitine shuttle
1:1
