1. Utilization of 5mM-glucose by slices of lactating mammary gland was decreased 33% on addition of acetoacetate (2mM) to the incubation medium. This inhibition was accompanied by increases in the intracellular concentrations of citrate and glucose 6-phosphate. 2. In the presence of acetoacetates the accumulation of pyruvate in the medium approximately doubled. 3. Insulin completely reversed th...

The SMA-12/30 method for serum glutamic oxalacetic transaminase assay gives higher values than are obtained with a reference spectrophotometric method for someserums.A modification of the manifold is made to permit the running of serum blanks. Blank corrections on 466 serum samples indicate that dialysis does not eliminate the need for the blank determination. Acetoacetate interferes in the SMA...

Silica Vanadic Acid, SVA, (oxo-vanadium has been supported on silica) as a dual Lewis and Bronsted acid ability was prepared and efficiently catalyzed one-pot multi-component condensation of enolizable ketones or alkyl acetoacetates with aromatic aldehydes, acetonitrile and acetyl chloride. The described reaction was produced β-acetamido ketone or ester derivatives in high to excellent yields i...

The search for renewable monomers radical polymerization techniques is of current interest due to the awareness sustainability requirements in chemical sciences. Herein, synthesis and reversible addition-fragmentation chain-transfer (RAFT) a methacrylate monomer based on ricinoleic acid as sustainable starting material presented. In addition, hydroxy moiety converted an acetoacetate order allow...

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...
