Flashcards in Lipids Deck (11):
Group of substances soluble in alcohol but not water (because non-polar substance), smaller amounts of oxygen
Triglyceride is made of
Glycerol and 3 fatty acids
What does a C=C do?
Change shape of chain
Kink push molecules apart so more fluid so lower melting point
Carboxyl ionises into
H+ and -COO-
Why are triglycerides good energy stores/sources?
Less oxygen atoms so higher proportion of hydrogen atoms so release more energy
Insoluble in water so doesn't affect water potential
Same as triglyceride but 1 fatty acid replaced by phosphate group
Selectively permeable, let's small non-polar molecules through
4 carbon based rings,
Not made from glycerol or fatty acids
