BIOL 212 Lecture Notes - Lecture 2: Condensation Reaction, Side Chain, Structural Formula
Document Summary
Monomers- individual units, link together to form polymers. Monomers polymerize though condensation reactions- releases a water molecule. Hydrolysis is the reverse reaction- breaks polymers apart by adding a water molecule. Side chain- 20 different amino acids found in our bodies, each has unique r group. If the answer to all 3 are no then you are looking at a nonpolar amino acid. Condensation reaction- bond the carboxyl group of one amino acid to the amino group of another. Polypeptide- a chain of amino acids linked by peptide bonds. Protein functions in cells- catalysis- enzymes speed up chemical reactions. Movement- motor and contractile proteins move the cell or molecules within the cell. Responsible for the storage, expression, and transmission of genetic info. Components: a phosphate group, a 5 carbon sugar, a nitrogenous base- dna-atgc rna- aguc.
