carboxylation

 [kahr-bok″sil-a´shun]
the addition of a carboxyl group, as to pyruvate to form oxaloacetate.

car·box·yl·a·tion

(kar-bok'si-lā'shŭn),
Addition of CO2 to an organic acceptor, as in formation of malonyl-CoA or in photosynthesis, to yield a -COOH group; catalyzed by carboxylases.

carboxylation

/car·box·y·la·tion/ (kahr-bok″sĭ-la´shun) the addition of carbon dioxide or bicarbonate to form a carboxyl group, as to pyruvate to form oxaloacetate.

carboxylation

[-lā′shən]
a chemical process in which a carboxyl group (COOH) replaces a hydrogen atom.

car·box·yl·a·tion

(kahr-bok'si-lā'shŭn)
Addition of CO2 to an organic acceptor to yield a -COOH group; catalyzed by carboxylases.

carboxylation

the addition of carboxyl (COOH) or carbon dioxide into a molecule as, for example, when carbon dioxide is added to ribulose diphosphate (C5) in the CALVIN CYCLE to give an unstable C6 product.

carboxylation

the addition of CO2 to an organic compound to create a carboxyl (-COOH) group

car·box·yl·a·tion

(kahr-bok'si-lā'shŭn)
Addition of CO2 to an organic acceptor to yield a -COOH group; catalyzed by carboxylases.

carboxylation (kärbok´səlā´shən),

n the chemical process by which a carboxyl group (COOH) is added or displaces a hydrogen atom.

carboxylation
