The PRO12 leaders were beaten 20-14 on a frustrating evening at the Scotstoun Stadium which also saw key players picking up injuries.
Paddy Wallace is now facing a "significant" spell on the sidelines after rupturing his anterior cruciate ligament during the game.
However it will give a chance for some of the younger players to don the Ulster jersey and Stuart Olding, who has stepped into the breach with Wallace out, said he is relishing the prospect of more playing time - but is sorry that it has come at a price.
"I relish the pitch time when it comes along but it's never nice to have any of your team mates have an injury, especially Paddy," he told UTV.
"He's playing fantastic this year and has probably come back to the form of his life and he's been great on and off the pitch, on the training park and on the Friday nights.
"Yeah, he'll definitely be missed by his team. In training he'll just pull me aside and have a few words with me about what I can maybe do better and what I'm doing well so yeah, he's been brilliant over the past two years."
Ulster lead Glasgow by three points at the top of the table with 16 games played, but Olding says they have no intention of resting on their laurels.
He continued: "I don't think there's any games that are easy in the Rabo at the moment.
"A lot of sides are playing some good rugby and any side that puts five tries on any Munster team no matter what stage of the season must be doing something right, so we're just focussing on ourselves at the minute trying to do what we do best and rectify some chances that were left out there on the pitch against Glasgow.
"Hopefully we can put in a good performance this Friday."
The game kicks off at 7pm at Ravenhill rugby grounds.
