2.2-LipidStructure&Fxn Flashcards
What are the 4 Vitamins that are lipid based?
ADEK
What are the two parts to a lipid that make it amphipathic?
The Hydrophobic Chain & the Hydrophilic Carboxyl group
Which fat type does an animal synthesize? Plant?
Animal=Saturated Fat; Plant=Unsaturated
Which method of counting starts with the end methyl?
Omega method
What is the MAIN Fatty Acid in our body? How many Cs?
Palmitic Acid; 16 C’s
How many Cs in Stearic Acid?
18Cs
Label the Cs when counting from the Carboxylic End…
First Carbon=C1; Second Carbon=Alpha Carbon; Third Carbon=Beta-Carbon
If a mammal can synthesize an unsaturated fat which carbon is the limit?
C9, a mammal enzyme cannot place a double bond beyond C9 (counting from the COOH end)
What is the relationship between long chain length and melting temp?
The LONGER the chain, the HIGHER the melting temp (more likely it will stay a solid)
What are the two VERY similarly named fats that are necessary in mammals but not synthesized by them?
LIN-OLE-IC acid & LIN-OLE-N-IC acid
What do the essential fatty acids need to be used to make? What is a specific example of one?
Ei-Co-San-Oids; a Pros-Ta-Glan-In
What is the important eicosanoid precursor that can only be synthesized from LIN-OLE-IC acid?
AR-ACH-ID-ONIC acid
What are the two components to a TriAcylGlycerol?
AN ESTER formed from Glycerol and 3 FAs
What is it called when there are different FAs in the same TriAcylGlycerol?
A mixed triacylglycerol as opposed to a simple TriAcylGlycerol
What is the Parent molecule for both TAGs and Phospholipids? (2 names for the same parent molecule)
Phos-Pha-Tid-Ate (Phos-Pha-Tidic Acid)..One of his favourite “crossroads” molecules!
