While choline does not compete with other nutrients for enterocyte transport, gut microbes can limit its bioavailability ( Escherichia coli , Pseudomonas aeruginosa , and Acinetobacter baumannii , choline uptake is mainly mediated by the BetT transporter, whose expression and transport activity are upregulated by hyperosmotic stress ( Figure 2 )
The SOD activity is determined spectrophotometrically based on the ability of the superoxide dismutase compound to reduce reactive oxygen species in an enzymatic reaction necessary for the production of an optically active compound
It has a wide distribution range and can reach different tissues and organs in the body, but mainly concentrated in areas related to growth hormone regulation, such as the anterior pituitary gland
They both stimulate growth hormone release, but through different mechanisms
