2.3.1.77 |
| Accepted name: |
triacylglycerol—sterol O-acyltransferase |
| Reaction: |
triacylglycerol + a 3β-hydroxysteroid = diacylglycerol + a 3β-hydroxysteroid ester |
| Other name(s): |
triacylglycerol:sterol acyltransferase |
| Systematic name: |
triacylglycerol:3β-hydroxysteroid O-acyltransferase |
| Comments: |
Tripalmitoylglycerol and, more slowly, other triacylglycerols containing C6 to C22 fatty acids, can act as donors. The best acceptors are 3β-hydroxysteroids with a planar ring system. |
