Question

PUFA stands for?
A) Polyunsaturated fatty acid
B) Polysaturated fatty acid
C) Polyunsaturated folic acid
D) None of the above

Answer 1

Hint: We are aware that fats are essential for living organisms. fats contain fatty acids, which are formed by a varied long chain of carbon with methyl terminus and a carboxylic acid head group. On the basis of the degree of saturation, they can be further divided.

Complete answer:
They possess the maximum number of hydrogen atoms, based on a number of double bonds present they are called monounsaturated fatty acid and polyunsaturated fatty acid (PUFA) respectively. If there is one double bond then it is termed as monounsaturated fatty acid and if it has two or more double bond it is called polyunsaturated fatty acid.

These PUFA can be further subdivided on the basis of their location of double bonds with respect to the terminal methyl in the chain. For examples, the two-class of PUFA n-3 and n-6 Fatty acid is of the most significant biological class and have their first double bond on either the third or sixth carbon from the chain terminus, respectively. The final carbon in the fatty acid chain is called an omega. If we talk about the essential fatty acids, they are to e taken from outside dietary sources. These essential fatty acids are converted to their downstream products through multiple elongations and desaturation step.

Therefore the correct answer is option ‘A’.

Note: Alternatively, seeds can be generated from nonsexual cells too. These plants are perfect clones of mother plants. These products are fully viable without pollination. due to segregation in the progeny, it is difficult to maintain hybrid characters a the upcoming generation
