Proteins are dynamic macromolecules. To study proteins a scientist needs to understand their chemical and physical properties. You are a scientist working in an analytical laboratory, your job description is to analyse proteins. A crude sample containing a protein is to be analysed. Discuss all steps and techniques that can be employed in order to isolate, characterise, and determine its amino acid sequence.
