Document Summary

" tend to be an necessarily a long chain of even # of carbons carbons. Trans fatty acids are common in processed foods , Monounsaturated fatty acid usually has c- c at two. " polyunsaturated fatty acid cannot have not a and lo in organisms c=c next to each other. Can be three different types of fatty acids. Two fatty and groups phosphate group glycerol attached to and one. Sphingosine is not a fatty acid chain. Glycerophospholipids the head group is used in myelin sheaths contain a sugar in l (hoh www. n. Have a hydrophilic head group and a hydrophobic tail group. Hydrophilic groups typically contain a phosphate group. Associate in a lipid bilayer (hydrophobic tails inside) Lateral diffusion (rapid) pirayysovnerse diffusion h" " r - flop , i flexion slow) diffuse within the bilayer via: = t fluidity since less packed: cholesterol concentration (flips affect of t) ( hinders. T fluidity due to chain- chain interactions)
