Lipids Flashcards
What are lipids
Lipids are a diverse group of non-polar hydrocarbons.
What are some types of lipids?
Some types of lipids include fat, oil, steroids, waxes, and phospholipids.
What are some lipid functions?
Some lipid function includes long-term energy storage, providing insulation, serving as building blocks for some hormones, and being an important component of cellar membranes.
What are the two main components of fats?
The two main components of fats are glycerol and fatty acids.
What are saturated fatty acids?
Saturated fatty acids are hydrocarbon chains that consist of only ONE single bond between carbons.
Do saturated fatty acids have the max number of hydrogen atoms?
Yes, saturated fatty acids have the max number of hydrogen atoms.
At room temperature, saturated fatty acids are what?
At room temperature saturated fatty acids are packed tightly together and exist as solids.
What are unsaturated fatty acids?
Unsaturated fatty acids are hydrocarbon chains that consist of one or more double bonds between carbons.
At room temperature, unsaturated fatty acids are what?
At room temperature, unsaturated fatty acids are liquid.
Polyunsaturated chains have many what?
Polyunsaturated chains have many double bonds.
Trans-fat cis configuration has hydrogen on what side of the chain?
Trans-fat cis configuration has hydrogen on the same side of the chain.
Trans-fat trans configuration has hydrogen on what side of the chain?
Trans-fat trans configuration has hydrogen on the opposite side of the chain.
What are waxes?
Waxes are long fatty acid chains that are hydrophobic.
What are phospholipids?
Phospholipids are two hydrocarbon chains and a phosphate group attached to a glycerol.
What is the structure of a phospholipid?
Phospholipids consist of two fatty acid tails that are hydrophobic, and the phosphate group (and attachments) form a hydrophilic head.
What is the primary role of phospholipids?
The primary role of phospholipids is to form cell membranes.
