1. Free fatty acids are a major component of membranes. True or false?
false; minor component
2. Fatty acids are ___ ___ acids
aliphatic carboxylic
3. Describe aliphatic carboxylic acids
generally long, unbranched, even number of carbon chains, length is usually 12 - 24, saturated FAs
4. Saturated fatty acids contain no C=C double bonds. True or false?
true
5. T C=C double bonds found in nature are what orientation
cis
6. In regards to major complex lipids, Triacylgycerols (TAG) have 3 acyl groups in ___ linkage to a molecule
ester
7. In regards to TAG, the storage of fatty acids is primarily in ___ tissue but also found as lipid droplets in
adipose
8. Phosphoglycerides (phospholipid) have a glycerol backbone. Describe this backbone.
two fatty acid molecules attached in ester linkage and a phosphate on the third hydroxyl glycerol. The
9. Phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, phospatidylinositol, and cardiolipin
phospholipids
10. Plasmalogens are an alkyl alcohol attached via an ___ linkage on position ___ of the glycerol
ether; 1
11. True or false? there may be plasmalogen forms of PC
true
12. Where are plasmalogens synthesized?
peroxisomes
13. This is a phospholipid that does not contain glycerol
sphingomyelin
14. Sphingomyelin is synthesized from what?
amino alcohol spingosine
15. Glycosphingolipids (not phospholipids) are composed of what?
sphingosine, a fatty acid, and one or more carbohydrate or carbohydrate derived structure
note: a sphingosine plus a fatty acid is called a ceramide
