Open Entry is an initiative that goals to make scientific analysis freely accessible to all. Up to now our group has revamped 100 million downloads. It’s primarily based on rules of collaboration, unobstructed discovery, and, most significantly, scientific development. As PhD college students, we discovered it troublesome to entry the analysis we wanted, so we determined to create a brand new Open Entry writer that ranges the enjoying subject for scientists the world over. How? By making analysis simple to entry, and places the educational wants of the researchers earlier than the enterprise pursuits of publishers.
We’re a group of greater than 103,000 authors and editors from 3,291 establishments spanning 160 nations, together with Nobel Prize winners and a number of the world’s most-cited researchers. Publishing on IntechOpen permits authors to earn citations and discover new collaborators, which means extra folks see your work not solely from your personal subject of examine, however from different associated fields too.

Summary
chapter and creator data
1. Introduction
Vitamin C often known as ascorbic acid (AA) is a vital nutrient in lots of multicellular organisms, particularly in people. Ascorbic acid is a water-soluble vitamin and is present in variable portions in fruit and veggies and organ meats (e.g. liver and kidney). Deficiency of vitamin C causes scurvy, widespread connective tissue weak spot and capillary fragility. Amongst chemists, it’s used as a reagent for the preparation of effective chemical substances, enzymatic reagent and nanomaterials. Consequently, the detection and quantification of ascorbic acid in meals samples, merchandise and nutraceuticals is receiving overwhelming significance amongst researchers, medical practitioners and likewise within the pharmaceutical and meals business. Determine 1 exhibits the schematic illustration of the sources and multifunctional functions of vitamin C within the metabolism of our physique.
2. Sources
Vitamin C (Determine 2) is abundantly accessible in lots of pure sources, together with recent fruit and veggies. The richest sources of ascorbic acid together with Indian gooseberry, citrus fruits equivalent to limes, oranges and lemons, tomatoes, potatoes, papaya, inexperienced and purple peppers, kiwifruit, strawberries and cantaloupes, inexperienced leafy greens equivalent to broccoli, fortified cereals and its juices are additionally wealthy sources of vitamin C.
One other supply of vitamin C is animals. They normally synthesize their very own vitamin C and are extremely concentrated within the liver half [1, 2]. Sources of vitamin C and its content material are given in Determine 3. Common day by day beneficial quantities of vitamin C for various ages are additionally given in Desk 1.
3. Features – “vitamin c function”
Vitamin C performs an necessary function in lots of physiological processes in people. It’s wanted for the restore of tissues in all elements of the physique. The necessary features of vitamin C embrace the formation of protein used to make pores and skin, tendons, ligaments, and blood vessels for therapeutic wounds and forming scar tissue, for repairing and sustaining cartilage, bones, and enamel and assist within the absorption of iron. It could additionally act as a lowering and capping agent for metallic nanoparticles.
4. Detection and sensing
Many analytical methods are used for the willpower of vitamin C in several matrices, equivalent to titrimetric [39], fluorimetric [40], spectrophotometric [41], high-performance liquid chromatography [42], enzymatic [43], kinetic [44, 45] and electrochemical, and so on.
5. Conclusion
Vitamin C performs a pivotal function in body-building course of and in illness prevention. The assorted features of vitamin C, together with the antioxidant exercise, formation of protein, tendons, ligaments and blood vessels, for therapeutic wounds and type scar tissue, for repairing and sustaining cartilage, bone, and enamel, and aiding within the absorption of iron, have been mentioned. This chapter will certainly profit the scholars, researchers and technologists globally.
