gsl-4a glycosphingolipid
A mixture of glycosphingolipids isolated from the Gram-negative lipopolysaccharide-free bacterium <em>Sphingomonoas paucimobilis</em>. The components all contain a tetrasaccharide unit, α-<small>D</small>-Man-(1→2)-α-<small>D</small>-Gal-(1→6)-α-<small>D</small>-GlcN-(1→4)-α-<small>D</small>-GlcA, attached to a 3-hydroxy-2-{[(2<i>S</i>)-2-hydroxytetradecanoyl]amino}alkyl lipid portion.
