L’ADN est un polymère (une grande molécule qui contient des unités répétitives) composé d’un 2′ désoxyribose (un sucre à cinq carbones), d’un acide phosphorique et de 4 bases azotées notés A, T, G et C. Les structures chimiques des bases sont indiquées ci-dessous. Notez que deux des bases ont une structure à double anneau appelées […]

Chapter 3 : Mass spectrometry
Mass spectrometry is one of the most used technique in laboratories because it allows to determine the structure of one molecule. For this technique, the sample should be a pure solution, containing only one molecule that will be analysed within a very short time period. It is why mass spectrometers are often queuing a chromatographic […]
Chapter 2 : Organic chemistry – Exercises
This section is a full part of the course and contains some reactions that were not addressed in the main course. It is challenging to understand by yourselves some mechanisms with the hints that are in the exercises. If you don’t succeed, don’t worry. The solutions and the description of the reactions are directly following […]
