Lipids Flashcards
Why are lipids water insoluble
Because they are non-polar which allows them to dissolve in non-polar solvents like acetone and choloroform
Which Biomolecule is not a polymer
Lipids
Why are lipids able to for cell membrane and boundaries within and between cells
Because of their insolubility in water
What are the three types of lipid molecule
Neutral lipids, phospholipids and steroids
Common name for neutral lipids
Fats and oil
The formation of most neutral lipids by dehydration synthesis involves…
Glycerol and fatty acids (product is called Triglycerides)
What family does glycerol belong too
Alchol
What’s the polarity of glycerol
Polar and water soluble
What’s the name of the covalent bond between the COOH ( one carboxyl group) and a hydroxyl group (one OH)
Ester linkage
How ester linkages do we have in the formation of triglycerides
3
Which melts on a lower temperature between unsaturated fatty acid and saturated fatty acid
Unsaturated fatty acid
An example of saturated fatty acid
Stearic acid
An example of unsaturated fatty acid
Oleic acid(it has. Double bond)
Hydrophobic
Water repelling or water fearing
How many carbon ring frame work. Does a steroid has
4 carbon ring
What distinguishes steroids from each other
The side groups or family attached to them
What group is a attached in a sterol molecule
OH group
Example of a sterol
Cholesterol
What makes a sterol slightly polar
Presence of OH group
The female sex hormone is ….
Estradiol (estrogen) with a OH group
The male steroid sex hormone is …
Testerone (with a double bond oxgen =O and a CH3)
What are the other types of lipids apart from steroids, phospholipids and neural lipids.
Chlorophyll and carotenoids (pigments that absorb light)
What’s the name of the hormone like steroid used by body builders
Anabolic androgenic steroids
Negative effect of saturated lipids
Clogs arteries
