Vitamin C (ascorbic acid) is a water-soluble vitamin which is the key antioxidant in the human body. It has been included on the WHO List of Essential Medicines, as it is used to treat scurvy, i.e. a disease causing an error in collagen creation due to a lack of ascorbic acid. Contrary to popular belief, regular intake of vitamin C as a nutritional supplement does not prevent one from getting a cold, but may shorten recovery time. Foods containing large amounts of vitamin C are citrus fruits, tomatoes, red peppers, and potatoes.

Vitamin C may be obtained with food in two forms, i.e. as ascorbic acid, which is a powerful reducer, or in oxidised form as dehydroascorbic acid. Although vitamin C is found in body fluids mostly in reduced form, ascorbic acid and dehydroascorbic acid are both biologically active and transform from one form to another during oxidation and reduction reactions catalysed by enzymes in the body.

Workforce in Chemistry

Chemistry is everywhere in our daily life and there are many jobs chemistry graduates do. Around 540,000 students study chemistry, physics, astronomy, and earth science in the EU. Chemistry graduates work as analysts, healthcare scientists, clinical chemists, forensic scientists, nanotechnologists, pharmacologists and toxicologists among others. Jobs for chemists, other scientists and engineers grew by 7% in the past five years. Jobs for technicians in the field grew by 2%. Overall, they account for 7% of all jobs in the EU. As of 2016, around 15 million European science and engineering workers are employed. They work in a variety of sectors, many of which related with chemical industry, such as agrochemicals, metallurgical, petrochemicals, pharmaceuticals, and plastics and polymers. Many also work in professional services, utilities, and in the education systems. In the next years, jobs for chemistry scientists, other researchers and engineers will increase by 13%, and jobs for science and engineering technicians will increase by 2%.
