WebOct 21, 2024 · Although TauT is a major β-alanine transporter into muscle cells (Jessen 1994 ), a notion that is supported by the dramatic decrease in β-alanine accrual in the hypotaurine-treated cells, β-alanine can also be transported by PAT1, a Na + -independent, H + -dependent transporter (Frolund et al. 2010 ). WebAlanine, a transamination product (see “Nitrogen > Nitrogen Reactions” in the top menu) of its cognate α-keto acid, pyruvate, can donate its amino group via transamination in the liver, and its carbon skeleton can be oxidized for energy derivation, or converted to glucose via the gluconeogenesis pathway for export to the blood and use by other …

Mechanistically, ... as revealed by a previous study indicating that alanine is essential for CD4+ T-cell activation . ALA is the derivative of L-alanine. WebMetabolomic profiling revealed that pyruvate-alanine conversion is enhanced in the absence of Lkb1. Mechanistically, inhibition of alanine transaminases restored glial differentiation in an mTOR-dependent manner, while increased alanine level directly inhibited the glial commitment of neural crest cells.
