degree of saturation
T or F: the shorter chain fatty acids or more unsaturated ones are harder - Answer -
False; they are softer

What does it mean when a fatty acid is saturated? - Answer -every available bond from
the carbon chain is holding a hydrogen atom
What does it mean when a fatty acid is unsaturated? - Answer -the fatty acid carbon
chain has a place where hydrogens are missing

unsaturation

point of unsaturation
What is a polyunsaturated fatty acid? - Answer -the carbon chain contains two or more
points of unsaturation
, What is polyunsaturated often abbreviated as? - Answer -PUFA
