Document Summary

Plasma membrane a layer of molecules around the cell that sepeates the interior cell from the external environment. Acts as a selective barrier, keeping nasty things out and letting good things in. Since it keeps the appropriate chemicals in an enclosed area, reactants collide more frequently and reactions happen more efficiently. Lipid the general term for c-containing compounds that are mainly hydrophobic and nonpolar. Part of the reason they are insoluble is because they are hydrocarbons, and the c-h bonds have almost 0 dipole movement. Composed of three fatty acids all connected to a glycerol molecule (3 carbons) Which is why fats are also called triglycerides. Glycerol and the fatty acids are joined together by ester linkages. Fats are not like macromolecules in the way that amino acids are. Various steroids are distinguished by their r-groups like aminos. The r group is hydrophilic while the rest is hydrophobic.
