Chapter 15 - Lipid Structure and Function Flashcards
1
Q
Lipids
A
Energy storage, cell membranes, endocrine signaling
2
Q
Fatty Acid
A
Carboxylic acid with hydrocarbon tail, covalent bond to proteins to tether membranes
3
Q
Saturated
A
Fully reduced methylene groups
4
Q
Unsaturated
A
Mono (1 C=C), Poly (2+ C=C)
5
Q
Triacylglycerol
A
3 fatty acids esterified to glycerol
6
Q
Saponification
A
Agitates micelles and creates hydrophobic interactions
7
Q
Glyceraphospholipids
A
Two fatty acids and a phosphate group attached to glycerol, membrane lipids
8
Q
Lipid Rafts
A
Receptors for extracellular signaling
9
Q
Hydrophobic in nature, less mass to store in the cell
A
Triacylglycerol
10
Q
Lipoprotein
A
Protein-rich phospholipid monolayer that surrounds a hydrophobic core with triacylglycerol and cholesterol ester
