Illumination of euglenas grown in the dark induces the formation of chloroplasts characterized by the simultaneous appearance of chlorophyll and galactosyl diglycerides in a relatively fixed ratio. The fatty acyl chains of the galactosyl diglycerides are constructed so that they can provide a stable lock-and-key fit with the phytol chains of chlorophyll in such a way as to localize the porphyrin structures of chlorophyll and space them for efficient photoreception. Light-starved photobiotic euglenas show chloroplast shrinkage with a concurrent partial loss of galactosyl diglycerides.
对在黑暗中生长的眼虫进行光照会诱导叶绿体的形成，其特征是叶绿素和半乳糖基甘油二酯以相对固定的比例同时出现。半乳糖基甘油二酯的脂肪酰链的构建方式使其能够与叶绿素的叶绿醇链形成稳定的锁钥配合，从而定位叶绿素的卟啉结构并使其间隔排列以实现高效的光接收。缺乏光照的光合生物眼虫会出现叶绿体收缩，同时半乳糖基甘油二酯会部分丧失。
