Available in PDF, EPUB and Kindle. Book excerpt: La mer a toujours fait rêver les hommes. Depuis l'Antiquité, ils ont exploré, commercé, vécu grâce à la mer. C'est d'elle qu'est venue la découverte des nouveaux mondes: jadis l'Orient des épices puis l'Amérique ; au XXe siècle, le développement de la civilisation du pétrole, du commerce mondial. Mais la mer ne peut se réduire aux espaces marins qui constituent cet irremplaçable milieu de communication : c'est un monde en soi dont les immenses profondeurs fascinent et intimident encore l'humanité — le rêve de Jules Verne. La science s'est penchée sur ce monde, au cours de la dernière génération et toujours davantage ; elle lui découvre une extrême richesse — l'incroyable diversité de la vie marine, les ressources minérales insoupçonnées des grands fonds — mais aussi d'une extrême fragilité, d'une chimie délicate. « Chimie », le mot est lâché : les équilibres chimiques et la diversité des éléments qui font la mer conditionnent au-delà de son évolution le devenir même de toute notre planète. La chimie contient les clefs qu'il nous faut connaître pour vivre en harmonie avec elle pour le bien de l'humanité. Des spécialistes de l'exploration et de l'étude scientifique de la chimie de la mer nous présentent ici comment les scientifiques peuvent : «comprendre la mer », ses courants profonds planétaires et séculaires qui jouent le rôle clef dans nos prévisions sur le changement climatique ; comment aussi les hommes peuvent « profiter de la mer » en y trouvant les ressources minérales (mais seront-elles exploitables ?) pour lesquelles nos continents nous promettent la pénurie, ou biologiques par des substances nouvelles promesses de bienfaits (médicaments par exemple). Mais ici comme ailleurs, sur mer comme sur terre, nos comportements sont bien irresponsables en matière d'environnement et une troisième partie de cet ouvrage, « la chimie pour aider la mer », appelle à l'utilisation de techniques pour lutter contre la pollution. Voilà un bel ouvrage de sciences qui vise à faire comprendre le fonctionnement des océans, et leurs enjeux économiques et environnementaux. C'est un livre de scientifiques, dense, documenté, sérieux, mais accessible dès lors qu'on a gardé quelques souvenirs des classes de physique et chimie du lycée. (Magazine DDM)

This was supported by ABRAHAM (1939), who identified both FMN and adenosine 5'-phosphate as hydrolysis products of FAD. The discovery of the coenzyme role of FAD has induced WARBURGand coworkers to engage in some speculation concerning the possibility that FMN is itself an artifact, produced through a breakdown of FAD. This aspect will be discussed later, in connection with recent work done on OYE in THEORELL'S laboratory. o NH 2 N CH3 .
