WebIn preterm infants, both hypo- and hyperglycemia are a frequent problem. Intravenous lipids can affect glucose metabolism by stimulation of gluconeogenesis by providing glycerol, which is a gluconeogenic precursor, and/or free fatty acids (FFA), which are stimulants of the rate of gluconeogenesis. WebAnswer (1 of 2): Most fatty acids are even chain (16, 18, 20) and those are broken down to Acetyl CoA, and the acetyl group has only 2 carbons. This is a problem because when Acetyl CoA enters the Citric Acid Cycle, two decarboxylations lose 2 CO2. The starting material for gluconeogenesis is ox... flood iecWebBoth pathways provide a set of amino acids, lipids, nucleotides, and glucose that will be used to synthesise new macromolecules .
