LIFE 102 Lecture Notes - Lecture 5: Adenine, Cytosine, Guanine
Document Summary
A methyl group makes a big difference in the action of these steroid hormones. Structural isomers: same in the content but different in structures. Cis isomer: the two x"s are on the same side. Trans isomer: the two x"s are on opposite sides. Geometric isomers: different arrangement of side groups next to a double bond. Enantiomers: different arrangements of side groups around the central c atom. The functional group shown in orange is the amino group. The functional group shown in yellow is the carboxyl group. The functional group circled in green is the sulfhydryl group. Macromolecules: polymers made from strings of monomer units. Dehydration: removes an h2o leaving behind a new bond in the polymer. Hydrolysis: break a water molecule, adding its components to the polymer. S: subset, or starts with sugar ( to remember ) Nucleotide: phosphate group + 5c- sugar + nitrogenous base. T: total unit or three parts ( to remember )
