Narrative:
Radar vectored out of sli for a visual approach to runway 25L at lax. TRACON descended us to 2;600 ft about 15 miles out. Advised we would follow an md-80. We acquired the md-80 and were cleared for a visual approach with us following the md-80. [The] md-80 descending on the ILS 25L. Profile was higher. When cleared for the visual approach the controller advised 'caution wake turbulence.' on the flight deck out loud I made a verbal call out to raise the 'threat level' as following an md-80 or md-11 tends to have bad wake turbulence. I zoomed out my inset map on my pfd to keep an eye on the distance of the md-80 TCAS target. The pickle is; final controller who cleared us for the visual approach asked us to maintain at least 180 knots until 7 DME (lax). At 180 knots; 2;600 ft; and 5-6 NM in trail of the md-80 with the glideslope for the ILS alive and about to capture (we were going to fly the profile high using V/south mode) before we would of ever established on the glideslope; still in altitude hold mode; we hit the wake and the aircraft was tossed to the side. My hand [was] on the a/P (autopilot) disc button; I immediately disconnected the a/P made the correction; held altitude; recovered and allowed the glideslope to fall to bottom of the scale; and then ran my planned high profile approach and landing. I monitored where the md-80 touched down; and landed the citation mustang at the halfway point down the runway (runway 25-left 10;000 ft long) aware that the common error pilots do in the final phases of a wake turbulence approach and landing is they re-join the glideslope. Not me; ran the final phase perfect. Point being; TRACON set me up for the encounter by having me at 2;600 ft with 180 knots until 7 DME. Whatever spacing they were trying to accomplish did not work. I noted winds at the field of 260/10 (directly down the runway).

At 180 knots; 2;600 FT; and 5-6 NM in trail of the MD-80 with the glideslope for the ILS alive and about to capture (we were going to fly the profile high using V/S mode) before we would of ever established on the glideslope; still in ALT hold mode; we hit the wake and the aircraft was tossed to the side.
