F) the TDG activity was significantly increased, indicating enhanced threonine catabolism. However, the TDG activity was almost exclusively modulated by aminoacetone accumulation.

Here we evaluated whether the quinolinic branch and/or the transamination side branch of the kynurenine pathway of Trp catabolism (leading to Quin or Kyna, respectively; Figure 1), become activated in severely ill patients who develop sepsis, and whether the increase of circulating Kyns results from impaired renal function.

The first postoperative energy stores to be used in catabolism are those that consist of:

Inhibition of protein degradation shifts catabolism towards degradation of fat storage molecules, which promotes an increase in lean body mass and a decrease in the storage fat.

Fat catabolism produces ketone bodies as byproducts, which accumulate in the blood and eventually spill out into the urine, putting the dieter into a state of ketosis.

Whether the athlete is a distance runner, an elite weightlifter, or a football player, two events will inevitably occur following an intense workout or competition: (1) a decrease in muscle glycogen (energy) stores and (2) an increase in muscle protein catabolism (protein breakdown).

Consequently, ureide accumulation as a result of a failure in ureide catabolism in the shoot was hypothesized as an explanation of [N.sub.2] fixation sensitivity in soybean to soil drying (Serraj et al., 1999a).

Hibernating mammals can survive several months without feeding by limiting their carbohydrate catabolism and using triacylglycerols stored in the white adipose tissue (WAT) as their primary source of fuel.

The rate of synthesis is controlled by 5-aminolevulinate synthase (ALS), the first enzyme of the pathway, likewise, heme oxygenase (HO), the first enzyme of the degradative pathway, sets the rate of heme catabolism. Liver contains many different hemoproteins, but the turnover of cytochrome [P.sub.450] ([P.sub.450]) quantitatively accounts for the major fraction of heme utilization.

He was commenced on dextrose containing intravenous fluids at a glucose infusion rate of approximately 10 mg/kg/min with 1 g/kg/day of intravenous lipid emulsion to suppress catabolism. The base deficit was corrected with sodium acetate and his metabolic parameters stabilized over a 24-h period.

[USPRwire, Thu Aug 01 2019] Chymosine is an enzyme, which helps in protein catabolism by hydrolysis of certain covalent chemical bonds.
