CHM 230 F'19 Amino acids/peptides Worksheet 1. Draw the structure, at pH 7, of a tetrapeptide that is composed of four different amino acid residues, each from a different category (classification). Draw an arrow to every peptide bond in this peptide. Identify by name the C-terminal residue and the N-terminal residue. Give the abbreviation of this tetrapeptide using three-letter codes. 2. Identify the amino acid residue whose R groun is drawn below in the "clothes line" format
Given a protein amino acid sequence (written out, 1 letter abbreviation, about 700 amino acids), how do i identify the N and C terminals? I know that N terminal is a free amine group and C is a free carboxyl group, but how do i know it is free? How do i identify it?
