All together now

Fancy a good singsong this Christmas? A painless way to revise your biochemistry? All you need is enthusiasm, a vague memory of popular tunes and a copy of the second edition of The Biochemists’ Songbook (Taylor & Francis £6.99, ISBN 07484 0416 3) by Harold Baum of King’s College, London. To the tune of Good King Wencelas, start singing “But beware for ethanol at levels elevated/In liver cells, in cytosol, is dehydrogenated/NADH to NADH the ratio’s distorted/There’s aldehyde toxicity (as recently reported)”.
