SOLVED:Ascorbic acid (Vitamin C ) has the following structure. O=C1OC(C(O)(O)CO)C(O)=C1O Protons a and b are acidic; proton a is the more acidic of the two. (a) Draw the structure of ascorbic acid as it exists at physiological pH(pH=7.4). Explain. (b) Using the curved-arrow notation, derive a resonance structure for the structure you drew in part (a); the two structures together will show that negative charge is shared between two oxygens.

SOLVED:The Lewis structure of vitamin C, whose chemical name is ascorbic acid, is drawn below (without lone pairs of electrons). (FIGURE CANNOT COPY) (a) What is the approximate value for the C-O-C bond angle in the five-member ring? (b) There are four OH groups in this structure. Estimate the C-O-H bond angles for these groups. Will they be the same value (more or less), or should there be significant differences in these bond angles? (c) Is the molecule chiral? How many chiral carbon atoms can

THE SKINCARE SCIENCE BEHIND VITAMIN C 🥼 🍊 Vitamin C, also known as L-ascorbic Acid, is a water-soluble vitamin commonly found in citrus fruits like oranges, lemons and grapefruits or produced synthetically. 🧬 The body cannot produce Vitamin C, but it is essential for the growth and repair of all cells in the body – including the skin. 🔬 When applied topically, Vitamin C is renowned for its ability to support collagen production, counteract oxidative damage and regulate melanin production. 🚩
