Dextrose-amino acid reactions

The reaction of dextrose with a nitrogen-containing compound, eg, amino acids or proteins, yields a series of intermediates which form pigments of varied molecular weight (Maikard reaction). The type of pigments produced is dependent on reaction conditions such as pH, temperature, and concentration of reactants. [Pg.289]

PN should provide a balanced nutritional intake, including macronutrients, micronutrients, and fluid. Macronutrients, including amino acids, dextrose, and intravenous lipid emulsions, are important sources of structural and energy-yielding substrates. A balanced PN formulation includes 10% to 20% of total daily calories from amino acids, 50% to 60% of total daily calories from dextrose, and 20% to 30% of total daily calories from intravenous lipid emulsion. Micronutrients, including electrolytes, vitamins, and trace elements, are required to support essential biochemical reactions. Parenteral... [Pg.1494]

GAB-88 is an infusion solution containing amino acids (3%), dextrose (7.5%), and electrolytes in a dual-chamber plastic bag. It has been evaluated in 39 non-operative patients who were unable to tolerate oral feeding or to take adequate amounts by mouth (1). When it was given in a daily dose of 1.0-2.5 liters for 7-19 days, there was an improvement in nutritional status without obvious adverse effects. There was mild vascular pain in four patients, but no phlebitis. There were no other clinically significant adverse reactions. [Pg.2700]

The chiral pool refers to readily available optically active natural products, some of which are commercially used in quantities of 10 -10 tonnes per year [5], Among them, the most inexpensive compounds are a-amino acids, like monosodium L-glutamate, or carbohydrates, like dextrose or sorbitol. The success of the second method depends on the availability of particular catalysts. One rather special example, how efficient stereoselective synthesis can work, is the syn-selective aldol reaction followed by a stereoselective alkene hydroboration and ketone reduction (Figure 1.8) which were used by Paterson et aJ. [26] to synthesize intermediates for the antibiotic oleandomycin. According to Paterson et al., four new stereocenters are formed in only two synthetic steps [9]. For the purpose of separating racemic mixtures... [Pg.11]
