Document Summary
Mbb222 exam vocab definitions: esters, anhydrides and acyl group transfers. Ester = acid + alcohol (cooh + oh) Diester group is compound containing 2 ester groups. A residue (can also be called a monomer) is a single molecular unit within a polymer. Ex. ) an amino acid can be referred as a residue that makes up the polypeptide polymer. Oligonucleotide describes a short nucleic acid with a relatively small number of nucleotides (50 or less) whereas a polynucleotide is a longer nucleic acid. Terminal groups are the free functional groups located at the end of a chain. N-terminus is the start of a protein with a free amine (-nh2) group, while the c-terminus is the end of the chain with a free carboxyl group (-cooh) fix to carboxylate and aminium ion. U1-03 first 5" vs. 3" group (e. g. phosphate or hydroxyl) in polynucleotide. A polynucleotide describes a chain of nucleotides joined together via phosphodiester linkages.
