Document Summary
Steroid hormones cholesterol- a precursor for steroid hormones. When placed in water the various lipids can form a variety of structures. The lipid bilayer is what is found in cells. The above lipids rearrange themselves into structures due to the hydrophobic effect. 17. 7 fluid mosaic model of a cell membrane. Passive and facilitated- from high concentration to low. Active transport- use energy in the form of atp from low conc. to high. Chapter 18 amines and amides: are derivatives of ammonia, the r groups cannot start with a carbonyl, the r groups do not have to be the same and may be aromatic. Iupac nomenclature: drop e of alkane parent name and replace with amine . Give the location of the amine group for chains: for 2o and 3o amines, the n alkyl prefix (in alphabetical order) is added to the parent compound name (longest chain)
