amino acid - Answer-molecules that contain: 1. an amino group (-NH2) 2. carboxyl group (-COOH) 3. R group/side chain - determines the chemical properties 4. Hydrogen atom (-H) main focus is on alpha aa's - not every amino acid is an alpha aa (GABA) - not every amino acid is coded for a codon - some aa's are converted to non codon coded aa for specific reasons - in eukaryotes they are all L configuration alpha amino acid - Answer-aa that the amino group and the carboxyl ...
