True or false: the number of double bonds are more important than the chain length in determining the melting point of a lipid
true
name the three steps of autoxidation?
• initiation • propagation • termination
name the requirements of the autoxidation
• presence of a free radical • oxygen • unsaturated fatty acids
what is resonance?
a radical divides itself over the double bond
what is termination?
when two radicals react resulting in a non-reactive product
name the two types of photo oxidation
o Type I : activated sensitizer reacts with lipid o Type II : activated sensitizer turns 3O2 into 1O2
name three factors that influence fat oxidation
• fatty acid composition • oxygen • storing conditions (o2, light, temprerature, surface area, water act (minimal at 0.2-0.4))
