Vitamin C in the body and an experiment to measure Vitamin C in cabbage.

Extracts from this document...

Introduction

Vitamin C The role of vitamin C in the body Vitamin C or ascorbic acid is a water soluble substance but is not heat soluble and is a vital vitamin for humans but unlike most mammals the human body can't produce its own, they have to eat foods such as, strawberries, cabbage, oranges, lemons, limes, red peppers, or kiwi fruit. 60 mg of vitamin C a day is enough to prevent scurvy. Vitamin C is vital for the body as it needs it to make a substance called collagen. Collagen is a type of protein found in many different types of tissue, such as skin, blood vessels, bones and cartilage. The body needs to regularly produce collagen. Without vitamin C, collagen can't be replaced and the different types of tissue break down leading to scurvy, some of the symptoms of scurvy are muscle and joint pain, tiredness, red dots on the skin or bleeding and swelling of the gums, leading to the teeth falling out. Vitamin c also helps the body's immune system vitamin C is found in high concentration in white blood cells and is consumed quickly when the body is fighting of a infection or disease so the level of vitamin C in the body drops. ...read more.

We then measured 10ml of the cabbage mixture and mixed it with 90ml of water, we then put this into a burette and added it to 1ml of DCPIP until the DCPIP turned from blue to pink, when it turned pink we stopped and measured how much of the liquid that was in the burette was left. We did this process for the 3 different types of cabbage Risk assessments: Hazards 1. Ethanoic acid 2. Beaker 3. Burette 4. DCPIP 5. sand 6. cabbage 7. Stand 8. pestle and mortar Risks 1. If the Ethanoic acid gets in your eye it could permanently blind you or damage your eyes. 2. if the beaker smashed you could cut yourself and it could get infected because of the bacteria on the glass 3. If the burette smashed you could cut yourself and it could get infected because of the bacteria on the glass 4. If the DCPIP gets in your eye it could damage your eye sight. 5. If the sand gets blown into your eye it could scratch your eye ball 6. If you are allergic to cabbage you could get a rash or your throat could swell up and your might no be able to breath. ...read more.

Conclusion

Eye site is a factor in the experiment because some people won't have as good eyesight as others so some might be able to detect the mixture turning pink where as others will be able to. Also colour blind people might not be able to tell the difference between the blue at the start and the pink at the end. Out of the 3 types of cabbage we used, raw, steamed and boiled the raw cabbage, our experiment showed that the raw cabbage had the most vitamin C, this is because it is its natural state and it's naturally high in vitamin C. The steamed cabbage came second over all, this is because the steaming method of cooking isn't as Our experiment showed us that the boiled cabbage had the lest vitamin C in it out of the three types of cabbage we tested, this is because vitamin C isn't heat soluble and the cabbage is cooked in boiling water. Overall I think the experiment we did was good because I think we preformed it correctly, sensibly and safely. If I was to do it again I wouldn't change anything. I think that the results are accurate enough to give a firm conclusion that raw cabbage has the most vitamin C in. ?? ?? ?? ?? Ryan Mycock 12 MLS ...read more.
