Trying to tie scurvy-plagued sailors of yore to the field of marine biology might be a bit of a stretch, but I had such an awesomely geeky \u201cAh-ha!\u201d moment regarding this classic maritime disease that I just had to share.\u00a0 (Plus I was reminded recently that we are fast approaching the 200th anniversary of Darwin\u2019s birthday next year, so what better time to start with the throw-backs to 19th century explorers?).<\/p>\n

\"Thank<\/a>
Thank your lucky oranges for preventing scurvy<\/figcaption><\/figure>\n

My light bulb moment went something like this. Any school child could probably tell you that the disease scurvy (causing bleeding gums, spotty skin, and general nastiness) is caused by a vitamin C deficiency.\u00a0 We\u2019ve all heard how things finally got better when those historic mariners sat around sucking limes.\u00a0 (Where is the team mom with those orange wedges when you need them?) But I never really understood how<\/em> Vitamin C actually saves the day – until I came across the write-up of a biomolecular archaeology symposium in Science magazine (a U.K. researcher is finding some evidence for scurvy by looking at the proteins in 17th and 18th century sailor skeletons), and which explained the basic connection.<\/p>\n

The answer, it turns out, is collagen<\/strong><\/a> \u2013 the most abundant protein in the human body.\u00a0 Twisted collagen fibers are in our hair, our tissues, even our bones.\u00a0 Anything that messes with this protein signals is bad news for the body \u2013 and scurvy is just that type of news.\u00a0 Collagen is chock full of proline<\/strong><\/a>, one of the of the amino acid building blocks that make up all proteins.\u00a0 So it stands to reason that anything that messes with proline messes up collagen, and before you know it, it\u2019s a scurvy mess.<\/p>\n

\"proline\"<\/a>
Your dime-a-dozen proline molecule<\/figcaption><\/figure>\n

So what goes wrong?\u00a0 Well, some proline molecules need hydroxyl groups added to them to help reinforce structure of the whole protein molecule.\u00a0 A hydroxyl is simply an oxygen and hydrogen hanging out and sharing electrons.\u00a0 These hydroxyl groups don\u2019t just appear on proline, enzymes have to put them there.\u00a0 And one of the cofactors (helpers) that these enzymes need to stick on the hydroxyl groups is \u2013 wait for it\u00a0 \u2013 Vitamin C!<\/p>\n

There you have it \u2013 without the right tools (Vitamin C) to help you construct proper nuts and bolts (proline), your beams (collagen fibers) won\u2019t be structurally sound.<\/p>\n

\"Proline<\/a>
Proline rocking an extra hydroxyl (OH) group - work it!<\/figcaption><\/figure>\n

And without a good framework, whatever you try to build is going to have some serious problems (like say, a human body).\u00a0 The builders of the Titanic should have known better<\/a> than to go against this string of logic, just to throw in another maritime example\u2026<\/p>\n

So now when mom tells you to drink that orange juice, you can thank her for saving you from gum disease and further misery \u2013 and<\/em> you can tell her how.\u00a0 Those poor sailors eating things like hardtack (which by all accounts, had the nutritional value of\u00a0 thinly disguised cardboard) didn\u2019t stand a chance. But in scurvy\u2019s defense:\u00a0 without it, Shakespeare would have been deprived of some of his choice insults<\/a>.\u00a0 What do you say to that, you scurvy jack-dog priests?<\/p>\n","protected":false},"excerpt":{"rendered":"
