## Abstract The photosynthetic preparation of D‐galactose‐^13^C~6~ and glycerol‐^13^C~3~ from __Gigartina corymbifera__ is described. The red marine algae biosynthesize the galactoside 2‐hydroxy‐1‐(hydroxymethyl)ethyl α‐D‐galactopyranoside (galactosylglycerol) during photosynthesis. The galactoside

✦ Synopsis
Abstract
^11^C‐labelled galactose, glycerol and mannitol have been prepared biosynthetically from ^11^C‐labelled carbon dioxide using species of marine algae. Following biosynthesis the labelled compounds are rapidly extracted from the algae and purified by liquid chromatography.
