Module 5 Flashcards
What are lipids?
Non-water soluble substances
How can you identify a saturated fatty acid molecule?
Every hydrogen is linked to a carbon.
How can you identify a unsaturated fatty acid molecule?
One section of carbon’s are double bounding to each other leaving out 1 section of hydrogen atoms.
How can you identify a polyunsaturated fatty acid molecule?
More than one section of carbon’s are double bounding to each other leaving out more than one section of hydrogen atoms.
Is the saturated fatty acid molecule straight?
Yes. The unsaturated fatty acid structure has a bend in it.
How do you determine the number of acetyl coA per fatty acid?
Take the number of carbon atoms and divide by 2. ( 16 carbons = 8 acetyl coA).
How do you determine how many rounds of beta oxidation need to take place?
Take the number of acetyl coA and subtract 1. ( 16 carbons = 8 acetyl coA. 8 acetyl coA - 1 = 7 rounds of beta oxidation).
How are triglyceride molecules identified?
3 separate fatty acids attached to a single molecule of glycerol.
How do you identify a phospholipid molecule?
2 fatty acids attached to a glycerol backbone with the third position containing phosphate group.
Whats unique about phospholipids?
They have a section of fat soluble parts and a part of water soluble parts (the phosphate side).
How do you identify a cholesterol molecule?
By the presence of four rings (similar to honeycomb).
What lipid do we use for the production of cell membranes?
Phospholipids.
What makes of the lipid belayer?
The water soluble polar heads and the hydrophobic fatty acid tails.
Which vitamins are fat soluble?
Vitamin A , D, E, and K
