sn-2 position is occupied mainly by saturated and trans-unsaturated fatty acids, so the content of cis-unsaturated fatty acids at the sn-1 position of phosphatidylglycerol ( pg) determines chilling resistance.

the enzyme modified synthesis of pg is an ideal way to produce a large number of phosphatidylglycerol with low production costs and mild conditions.

选择酶改性方法合成PG需要的投入的成本相对低，同时条件温和，是用来大量制备磷脂酰甘油的一种较为理想的方法。
