Transporter's Function Provides Support For Eating Vegetables, Limiting Antibiotics
Upward Quest
"A transporter in the colon called SLC5A8 plays an important role in enabling the colon to get the last bit of good out of food before the unusable is flushed away, according to research currently published online as an accelerated communication in the Journal of Biological Chemistry.
"In an amazing model of efficiency, good bacteria in the colon produce an enzyme that releases glucose found in plant cell walls, the leftovers of broccoli and other vegetables, fruits and cereals, which cannot be digested in the small intestine. In the oxygen-less environment of the bacteria-packed colon, bacteria ferment this glucose to use for energy which also results in the production of short-chain fatty acids, the preferred nutrients for colon cells.
"Medical College of Georgia researchers have found – in animal and human cells – that SLC5A8 is a final piece of the model, a transporter expressed by colonic cells to absorb the just-produced, energy-packed short-chain fatty acids."
