If there are a lot of protons (H +) in the system it is more likely to go from right to left. Which way it goes depends on the external conditions.
It is important to know that this reaction is reversible. You can find the formula for the acidic reaction from ascorbic acid below. The structural formula of vitamin C, or ascorbic acid. Such a ring is common in a lot of other special food molecules and is especially good at holding onto electrons. This ring is actually very important for the activity and properties of vitamin C. In the structural formula below you can see how the atoms in the molecule are connected. The chemical formula of vitamin C is C 6H 8O 6. It does so (as does any acid) by increasing the concentration of proton (H +) in the water. This means that if you add ascorbic acid to water it will turn the water slightly sour, the pH-value will drop below 7. Ascorbic acid is vitamin C, it’s just the chemical name. When reading about vitamin C, you might come across the name ascorbic acid. Luckily, once you understand how this happens, there are ways to prevent it. It gets lost quite easily, by leaving your glass of orange juice out for too long but especially during processing of food. To make matters more complicated: our bodies can’t make our own vitamin C and, vitamin C is pretty unstable. And still, scurvy isn’t completely gone from the world, only showing just how important getting enough vitamin C is for our bodies. Unfortunately, the disease, and its cure, had to be discovered several times, being forgotten in between, before being properly preventable. You’ve likely heard of the disease before: scurvy. No, it was a lack of vitamin C (ascorbic acid). Reason for a lot of these deaths therefore wasn’t a lack of carbohydrates, proteins, etc.
They wouldn’t necessarily run out of sufficient calories, they did run out of those oh so important fruits and vegetables. And as you can image, they didn’t have the freshest of food supplies on board. Trips to the East, essential for European traders to get those beloved spices, fabrics and other trading goods, used to take months. Only a few centuries ago, European (and likely many others) seamen died by the dozens during months long sea voyages to the East.
