Product Description

What is L-Alanine?

L-Alanine is the simplest chiral proteinogenic amino acid, carrying a small methyl side chain that gives it a mildly hydrophobic character without significant steric bulk. It plays a central metabolic role in the glucose-alanine cycle, in which muscle tissue converts pyruvate to alanine to safely transport nitrogen to the liver, where it’s converted back to pyruvate for gluconeogenesis.

Uses of L-Alanine

L-Alanine is widely used as a nutritional and food-fortification ingredient, and as a component of parenteral (IV) amino-acid infusion formulations in pharmaceutical manufacturing. It’s also a standard cell-culture media ingredient, a peptide-synthesis building block, and a foundational reagent in biochemical research studying amino-acid and glucose metabolism.

FAQs: L-Alanine

Mainly as a nutritional/food-fortification ingredient, a component of parenteral nutrition formulations, a peptide-synthesis building block, and a cell-culture media and biochemical research reagent.

It's a metabolic pathway where muscle tissue converts pyruvate to alanine to safely export nitrogen to the liver, which converts it back to pyruvate for glucose production — L-alanine is the central shuttle molecule in this cycle.

No — it's non-essential; the body can synthesize it from pyruvate via transamination.
