Identify the components contained in each of the following lipids.
Question 1:
Part A
estrogen
Check all that apply.
- glycerol
- fatty acid
- phosphate
- amino alcohol
- steroid nucleus
- sphingosine
Solution:
A) glycerophospholipid
as the name implies:
Glycerol, fatty acids (long acid chains), poshophate group, and amino alcohol (amino+alcohol groups)
Question 2:
Part B
cephalin
Check all that apply.
- glycerol
- fatty acid
- phosphate
- amino alcohol
- steroid nucleus
- sphingosine
Solution:
B) ​sphingomyelin
as the name imploies –> sphingosine
sphingosine is typically accompanied by phosphate group
Then, the long chain of NH3+ R – R OH is actually an amino alcohol
Finally, due to COO – long R chain –> fatty acid
Question 3:
Part C
wax
Check all that apply.
- glycerol
- fatty acid
- phosphate
- amino alcohol
- steroid nucleus
- sphingosine
Solution:
C) aldosterone
This is simple, as the name implies “sterone” there is only steroid present in the group
Question 4:
Part D
triacylglycerol
Check all that apply.
- glycerol
- fatty acid
- phosphate
- amino alcohol
- steroid nucleus
- sphingosine
Solution:
D) linoleic acid
as the name implies, there is –> fatty acid
also, no other component is present, since this is just a fatty acid by itself
Conclusion:
This article helps you understand to Identify the components contained in each of the following lipids.
