Question

Which of the following vitamins of alicyclic series?
A) Vitamin C.
B) Vitamin K.
C) Vitamin B.
D) Vitamin A.

Answer 1

Hint: We know that an alicyclic compound contains at any rate one all-carbon rings which may be either inundated or unsaturated, anyway don't have fragrant character. Alicyclic blends may have in any event one aliphatic side chain associated.

Complete step by step answer:
The structure of vitamin A is,

We have to remember that the vitamin A will be a group of unsaturated dietary natural mixes that incorporates retinol, retinal, and a few provitamin carotenoids (most quiet beta-carotene). Vitamin A has various capacities: it is significant for development and improvement, for the support of the safe framework, and for good vision. Vitamin A is required by the retina of the eye as retinal, which joins with protein opsin to shape rhodopsin, the light-engrossing molecule vital for both low-light (scotopic vision) and shading vision. Vitamin A likewise capacities in an altogether different function as retinoic corrosive (an irreversibly oxidized type of retinol), which is a significant hormone-like development factor for epithelial and different cells. Hence Option D is correct.
The structure vitamin C is,

We have to know that the Vitamin C also called as ascorbate and ascorbic acid is a nutrient found in different nourishments and sold as a dietary supplement. It is utilized to forestall and treat scurvy. Hence option A is incorrect.
The structure vitamin K is

Vitamin K alludes to basically comparative; fat-solvent vitamins found in nourishments and advertised as dietary supplements. Hence option B is incorrect.
We have to remember that the vitamin is a class of water-dissolvable nutrients that assume significant parts in cell digestion and union of red blood cells. Though these nutrients share comparative names (B1, B2, B3, and so on), they are artificially particular mixes that regularly exist together in the equivalent foods. Hence option C is incorrect.

So, the correct answer is Option D.

Note: We must remember that the Wittig reactions are helpful for industrial synthesis of fat-soluble vitamins and carotenoids that are needed within the chemical industry. The foremost part of this synthesis was connecting the individual molecular building blocks with the formation of an olefinic double bond. The Wittig reaction was an utterly new path for the synthesis of the natural products and also the effectiveness of which was to be quickly established in the path of investigations on the economic vitamin A synthesis. Within the preparation of the industrial vitamin A synthesis a crucial obstacle was mounted and the propagation of the Wittig the synthesis was given a further impulse. Underneath the need of creating a cost-effective method for the assembly of sustenance A, it absolutely was vital to regulate the reaction erstwhile planned by GI Wittig to industrial conditions. Proton acceptors and solvents that were industrially pronto offered and industrially simple to handle, further as an easy synthesis for the supplementary chemical agent triphenylphosphine had to be found.
