Lipids are long straight chain of what?
Hydrocarbon-carbon and hydrogen atoms linked together by non-polar covalent bonds.
Are lipids hydrophobic or hydrophilic?
Hydrophobic.
Th e structure of lipids give a fatty acid a ______ end and a ________ end.
Polar and non-polar
Lipids are very important in _________________.
Energy storage.
What is the monomer of lipids?
Glycerol and 3 fatty acids.
Monomers are ____________ covalent bonds formed through _________________ synthesis.
Non-polar
Dehydration
What are the functional groups of glycerol and 3 fatty acids?
Glycerol contains a hydroxyl group.
Fatty acids contain the carboxyl group.
What are the functions of glycerol?
Glycerol is responsible for energy storage. It can store twice as much as polysaccharides.
Glycerol is also responsible for phospholipids in cell membranes.
Glycerol is very important for protection of vital organs and insulation of the body.
What are the different types of glycerol?
Saturated Fat
Unsaturated Fat
Trans Fat
Lipids:
Lipids are diverse compounds that are grouped together because they share one trait- they mix poorly with water.
What is the monomer of a lipid?
Glycerol and 3 fatty acids.
What kind of bond is glycerol and 3 fatty acids?
Non-polar covalent bonds.
Triglycerides are what?
Another name for fats.
Functional Groups of glycerol and 3 fatty acids.
Glycerol-hydroxyl
Fatty acids-carboxyl
What is an unsaturated fat?
A fat with less than the maximum number of hydrogens.
What kind of bonds do unsaturated fats contain?
Double bonds, sometimes even triple bonds.
What is a hydrogenated oil?
An unsaturated fat that has been converted to a saturated fat by adding hydrogen. (NOT GOOD)
What is a saturated fat?
A saturated fat contain the maximum number of hydrogen.
Saturated fats contain what kind of bonds.
Single bonds.
The kinks in unsaturated fats prevent molecules from _____________________ and ___________at room temperature.
Packing tightly together and solidifying.
Saturated fats __________ at room temperature and pack _________ together.
Solidifies and packs tightly.
Saturated fats are linked with what?
Atherosclerosis (heart attacks, clogging of the arteries)
What is a grand fat?
Trams fat are monk or poly unsaturated fats but during food processing around them full of hydrogen, resulting in too many.
