Sulfolipids are a class of lipids which possess a sulfur -containing functional group. An abundant sulfolipid is sulfoquinovosyl diacylglycerol, which is composed of a glycoside of sulfoquinovose and diacylglycerol. In plants, sulfoquinovosyl diacylglycerides (SQDG) are important members of the sulfur cycle. [1] .

2011年7月1日 · The sulfolipid SQDG is a relatively minor lipid compared to the galactosylglycerides comprising about 4–7% of total leaf lipids. It is found in most photosynthetic and a few non-photosynthetic organisms. The relative SQDG content in plant and algal tissues varies from 2% to 50% of total polar lipids in marine plants and algae [6], [7], [8], [9].

Sulfolipids are located in the thylakoid membrane and contribute to maintaining membrane function and structure. They constitute the anionic fraction of the mono- and digalactosyl diacylglycerols (Kobayashi, 2016). Sulfoquinovose is the building block of sulfolipid and also the major component of the biological sulfur cycle (Roy et al., 2003).

Aside from sulfur amino acids, sulfolipid represents a considerable sink for sulfate in plants. Plant sulfolipid is found in the photosynthetic membranes of plastids and provides negative charge in the thylakoid membrane where it is thought to stabilize photosynthetic complexes.

2002年4月16日 · The sulfolipid sulfoquinovosyldiacylglycerol is one of the three nonphosphorous glycolipids that provide the bulk of the structural lipids in photosynthetic membranes of seed plants. Unlike the galactolipids, sulfolipid is anionic at physiological pH because of its 6-deoxy-6-sulfonate-glucose (sulfoquinovose) head group.

Higher-plant chloroplast membranes are composed primarily of four characteristic lipids, namely monogalactosyldiacylglycerol, digalactosyldiacylglycerol, sulfoquinovosyldiacylglycerol (SQDG), and phosphatidylglycerol.

Sulfolipids are anionic lipids with a sulfur-containing functional group. In plants and cyanobacteria, the major sulfolipid is sulfoquinovosyl diacylglycerol (SQDG), which is composed of a glycoside of sulfoquinovose and diacylglycerol.

This chapter describes plant sulfolipid. Sulfoquinovose and its glycosides, glyceryl sulfoquinovoside and the sulfolipid, comprise the most concentrated anionic sugar derivatives in plants. As salts of a very strong sulfonic acid, they are anionic under all conditions. Sulfolipid possesses an extremely hydrophyllic moiety and two fatty ester ...
