3-[alpha-D-galactosyl-(1->6)-beta-D-galactosyl]-monoacyl-sn-glycerol
3-[alpha-d-galactosyl-(1->6)-beta-d-galactosyl]-monoacyl-sn-glycerol
A digalactosylglycerol derivative in which the digalactosyl moiety is α-<small>D</small>-galactosyl-(1→6)-β-<small>D</small>-galactosyl at <em>O</em>-3, with either <em>O</em>-1 or <em>O</em>-2 acylated. [Either R1 = -C(=O)R and R2 = H, or R1 = H and R2 = -C(=O)R. The molecular formula is C<small><sub>16</sub></small>H<small><sub>27</sub></small>O<small><sub>14</sub></small>R, where R represents the aliphatic group attached to the acyl carbonyl.]
