1.20 Synthesis of fatty acids Flashcards
1
Q
Draw AcCoA transport: Mito → Cytoplasm
A
2
Q
Draw β-reduction (synthesis) of even carbon FAs
Step 1 → 4
A
3
Q
Draw β-reduction (synthesis) of even carbon FAs
A
4
Q
After β-reduction (synthesis) of even carbon FAs, what is the fate of Fatty acyl-SACP?
A
- Fatty acyl-SACP binds to condensing enzyme
- Step 4 repeats
This repeats until FA reaches desired carbon length
5
Q
Draw the reaction at the end of β-reduction (FA synthesis)
A
6
Q
Give the regulation of β-reduction (FA synthesis)
A
7
Q
Give the location of Fatty acid synthesis
A
- Liver
- Adipose
- Mammary gland
Cytoplasm
8
Q
Draw β-reduction (synthesis) of odd carbon FAs
A
Synthesis then continues from step 3
9
Q
Draw the formation of unsaturated fatty acids (Under Δ9)
A
10
Q
Draw the formation of unsaturated fatty acids (Above Δ9)
A
11
Q
Conjugated unsaturated fatty acids
A
- ØCH2 found between double bonds
- Polyunsaturated
- E.g conjugated linoleic acid
12
Q
Trans-fatty acids are found…
A
- Ru. fatty milk
- LDL ↑
