00:00 The final water soluble vitamin that we will cover is vitamin C or ascorbic acid. 00:09 Much more simple. 00:10 You can take a breath. 00:11 It has an important role in collagen formation as well as immune system function. 00:18 You probably were well aware of that. 00:20 And then collagen you are probably also aware that it is involved in many, many tissues. 00:27 It's part of most connective tissues. 00:30 So anywhere that we see a high prevalence of connective tissues and vitamin C deficiency, we can see some issues. 00:39 So ascorbic acid or C deficiency results in all of these sorts of symptoms. 00:44 Poor wound healing. 00:46 We'll see gum abnormalities. 00:49 We can see bruising or subcutaneous like point hemorrhaging as looks like petechia and loss or missing teeth. 01:00 As well as significant joint pain. 01:02 So again anything that has a lot of collagen in connective tissue. 01:09 And the issue is in binding these collagen monomers together. 01:14 So the cross linking vitamin C is involved in the cross linking of those two monomers in order to form the matrix that we see in our connective tissues. 01:26 So on that note, I think we've wrapped up the coverage of all of our water soluble vitamins. 01:33 And I look forward to seeing you when we talk about the fat soluble vitamins.
The lecture Vitamin C (Ascorbic Acid) by Georgina Cornwall, PhD is from the course Nutrition.
