W. H. Auden, 1939
Wystan Hugh Auden, known more commonly as W. H. Auden, (February 21, 1907 – September 29, 1973) was an English poet, one of the most influential of the twentieth century. Younger than William Butler Yeats and T.S. Eliot, the two titans who had dominated English turn-of-the-century verse, Auden assimilated the techniques of these and the other modernists, becoming a master of poetry that was both rigorously formal and radically new.

Auden was a poet of prodigious talent and output, living at a time of immense transition both in the world at large and in the poetic scene in particular. During the decades in which he lived, the ambitious, Modern poetry of Ezra Pound, Eliot, and Yeats would give way to a flood of contemporary poetic schools—from the Confessionalism of Robert Lowell to the formalism of Philip Larkin to the postmodernism of John Ashbery—all of which have competed for dominance in poetry ever since. Auden lived right at the center of this major sea-change in poetic development; his double-life as a British and American citizen only heightened his impact on the Anglophone world; and his influence, both as a beacon of poetry's traditional past and a harbinger of its radical future, is virtually unmatched by any other twentieth-century poet. He lived a double-life in another sense: His interests changed dramatically, as he turned from his early political orientation to a more inward focus as a result of a religious epiphany.

An enzyme is a biological catalyst that regulates the rate of a chemical reaction in a living organism. Most enzymes are proteins, though certain nucleic acids, called ribozymes, are also capable of catalytic activity.

Enzymes are essential to sustain life because most chemical reactions in biological cells, such as the digestion of food, would occur too slowly or would lead to different products without the activity of enzymes. Most inherited human diseases result from a genetic mutation, overproduction, or deficiency of a single critical enzyme. For example, lactose intolerance, the inability to digest significant amounts of lactose, which is the major sugar found in milk, is caused by a shortage of the enzyme lactase.
