Circle the eight isoprene units in 尾-carotene.

Short Answer

Expert verified

尾 carotenoids are natural carotenoids classified as tetraterpenes.尾-carotene has eight isoprene structures, eleven conjugated double bonds, and forty carbons backbone. It is composed of two retinyl groups and is irregular terpenewith4-4 linkage.

The long-term health effects of eating partially hydrogenated vegetable oils concern some nutritionists because many unnatural fatty acids are produced. Consider the partial hydrogenation of linolenic acid by the addition of one or two equivalents of hydrogen. Show how this partial hydrogenation can produce at least three different fatty acids we have not seen before.
