Photorespiration: metabolic pathways and their role in stress protection [PDF]

, 2000
Photorespiration results from the oxygenase reaction catalysed by ribulose-1,5-bisphosphate carboxylase/ oxygenase. In this reaction glycollate-2-phosphate is produced and subsequently metabolized in the photorespiratory pathway to form the Calvin ...

Encapsulation of ascorbic acid promotes the reduction of Maillard reaction products in UHT milk [PDF]

, 2016
The presence of amino groups and carbonyls renders fortified milk with ascorbic acid particularly susceptible to the reduction of available lysine and to the formation of Maillard reaction products (MRPs), as Nε-(Carboxyethyl)-L-lysine (CEL), Nε ...
