Fatty acyls
No letter prefix is required
Examples:
20:2(10Z,13E)
20:2(10Z,13E)(9Ke,15OH[S]){8a,12b}
Square brackets, e.g. [S] are used to denote R/S chirality.
Numbers inside the curly brackets denote carbons at a ring junction for prostaglandins. "a" and "b" refer to alpha(down) and beta(up) orientation of the chains at ring junctions.
