Which seaweed derived sugar is widely used to culture lab grown meat?

 title: 'Steak of the Art: The Fatal Flaws of In Vitro Meat'

The seaweed-derived sugar commonly used to culture lab-grown meat is alginate, which acts as a gelling agent critical for cell scaffolds. Alginate is particularly valued for its biocompatibility and ability to create the necessary texture in cultured meat products[4][5].

In lab-grown meat production, alginate scaffolds help support nutrient transport and cell adhesion, which are essential for growing muscle tissues[4].
