Term
Whats it called when you have both polar and non polar regions?

Definition
Waxes, isoprene based lipids (steriods), fatty acids, triacylgcerols, Glycerophospholipids, sphingolipids
Term
Most Fatty acids ?
Definition
Are rarely found free and are composed of an even number of carbon (carboxy included)
Term
How is the short hand convention used
Definition
#C:#Db (delta x)
ex; 18:1 (delta 9)
Term
Name off the saturated fats from lowest carbon to highest

Term
what are the three things that you ask for to classify or id fatty acid
Definition

5,8,11,14
Term
Kinks in the bilary are caused by what and do they entail on fluidity and Melting point
Definition
Kinks are caused by cis double bonds in alkyl chain of fatty acids, and they reduce vand derwaals interaction in membrane. resulting in a increase in membrane fluidity and a deacreas in Melting point
Term

Archidonic acid
Term
One function of fatty acids
Definition
serve as precursors for eicosanoids
Term
Eicosanoids ? ex. ?
Definition
hormonelike effects on procceses
example (progastglandins)
Term
which oil is the healthiest
Definition
Canola oil high poly low saturated
Term
Who and how are trans fatty acids made ? Where could they be found
Definition
Bacteria form them via double bond migration and isomerization in ruminants, butter, milk and cheese. the meat of these animals have some transfat as a result.
Processed fats (ex. margarine) made by partial hydrogenation contain various trans fat aswell
Term
Structure of TAG triacyglycerol
Definition
glycerol with 3 fatty acids esterfied
Term

mixed triacylglycerol
Term
Mono and diacyl glycerols ?
Definition
can be found but are rare
Term
why are TAG a major energy source
Definition
1- highly reduced 1g=38kj vs 1g=17 kj (proteins and carbohydrates)
2- efficent packing (highly anhydrous)
