SLC1A5
SLC1A5 glutamine transporter — the molecular target that 1 compounds in the wiki act on.
In one line: A doorway that pulls glutamine into cells — fuel for your gut lining.
SLC1A5 is a transporter that moves the amino acid glutamine into cells. Glutamine is the main fuel for the cells lining your gut, which is why glutamine supplements are used to support a damaged or "leaky" gut, especially after heavy training or illness. For a healthy person eating enough protein, the benefit is smaller.
