An aldol condensation is an organic reaction in which an enol or an enolate ion reacts with a carbonyl compound to form a Î²-hydroxyaldehyde or Î²-hydroxyketone, followed by a dehydration to give a conjugated enone. Aldol condensations are important in organic synthesis, providing a good way to form carbonâcarbon bonds.For example, the Robinson annulation reaction sequence features an aldol condensation; the Wieland-Miescher ketone product is an important starting material for many organic syntheses.owever, the aldol reaction is not formally a condensation reaction because it does not involve the loss of a small molecule. The reaction between an aldehyde/ketone and a carbonyl compound lacking an alpha-hydrogen (cross aldol condensation) is called the Claisen-Schmidt condensation.

Manning's Broncos actually have the three oldest starting quarterbacks in Super Bowl history. John Elway was 38 when he started Super Bowl XXXIII for Denver in 1999, his last game as an NFL player. (Elway is also the oldest quarterback to win a Super Bowl, as the Broncos beat the Atlanta Falcons 34-19). Manning was 37 when he started Super Bowl XLVIII two years ago for the Broncos against Seattle two years ago.
