Studies have been focused on their metabolism which shows that BCAA are firstly reversibly catabolized to their respective [alpha]-keto acids by branched-chain amino acid aminotransferase (BCAT) and then irreversibly oxidatively decarboxylated
into acyl-COA derivatives by a mitochondrial branched-chain [alpha]-keto acid dehydrogenase (BCKD) complex (Harper et al.
The oxygenated and decarboxylated
blood is returned to the patient's systemic arterial circulation.
Here, SAM is decarboxylated
by adenosylmethionine decarboxylase to form S-adenosyl-5'-3-methylpropylamine.
When flakes of softwood are exposed to heat during the press cycle, and at temperatures as low as 90 [degrees]C, losses in lignin, holocellulose, and acetyls combined with a general degradation of the hemicellulose to various sugars results in a complex mixture of acids generally described as decarboxylated
rosin acids (Hawley's Condensed Chemical Dictionary 2002, Kolin and Dannon 1998).
It did not hydrolyse arginine though ornithine was decarboxylated
In this GABA shout, the glutamate is then decarboxylated
by GAD in a reaction that consumes a cytosolic proton and yields GABA (this has been implicated as a mechanism by which the pH of the cytoplasm may be raised as a result of proton influx due to stress) (Carroll et al.
The algal fatty acid product is catalytically decarboxylated
and converted into paraffinic hydrocarbons (alkanes), followed by mild hydrocracking and hydroisomerization to make biojet fuel comprised of C10-C15 branched paraffins.
They can be decarboxylated
to lead to ester functions.
