Ketone aldehydes in tissues.

Ketone aldehydes in tissues.

Interaction of amines with ketone aldehydes and unsaturated aldehydes.

The optical changes occurring during the interaction of amines with ketone aldehydes or unsaturated aldehydes are accompanied by strong electron spin resonance signals, and can thus be explained as due to the transfer of one whole electron in the ground state.

Utilization of ketone bodies by mammalian tissues.

It is now well established that ketone bodies (acetoacetate and D-3-hydroxybutyrate) are metabolized by many mammalian tissues and that the rate of utilization is mainly dependent on their availability in the circulation. The aim in this contribution is to summarize briefly the pathways of ketone-body metabolism and to discuss the role of ketone bodies m various tissues. For a detailed review o...

The determination of higher fatty aldehydes in tissues.

The determination of the content and distribution of the higher aliphatic aldehydes in tissues have depended on modifications (l-3) of the Feulgen procedure which employs the fuchsin-sulfurous acid reagent. However, several observers, notably Ehrlich et al. (2), have commented on two features of this procedure which make its application difficult: The Schiff reagent reacts with a wide variety o...

Ketone Substance Production and Destruction in Certain Tissues of Diabetic Dogs*

The metabolism of the acetone substances in the intact organism has been the subject of numerous investigations, but researches on the function of individual organs have been relatively meager. Embden and his collaborators (1, 2) concluded from experiments on excised tissue perfused with the animal’s own blood that the liver was the source of acetone bodies. Chaikoff and Soskin (3) showed that ...
