Question
Following are the statements with reference to 'lipids': (a) Lipids having only single bonds are called unsaturated fatty acids. (b) Lecithin is a phospholipid. (c) Trihydroxy propane is glycerol. (d) Palmitic acid has 20 carbon atoms including carboxyl carbon. (e) Arachidonic acid has 16 carbon atoms.
Choose the correct answer from the options given below:
(b) and (c) only
(b) and (e) only
(a) and (b) only
(c) and (d) only
the evaluation of the statements is as follows: Statement (b) is correct: Lecithin is specifically cited as an example of a phospholipid . Statement (c) is correct: The text defines glycerol as trihydroxy propane . Statement (a) is incorrect: Fatty acids without double bonds are saturated; unsaturated fatty acids are those with one or more C=C double bonds . Statement (d) is incorrect: Palmitic acid is recorded as having 16 carbons, including the carboxyl carbon .
Therefore, only statements (b) and (c) are accurate.
This question aligns with the NEET BIOLOGY syllabus, specifically targeting concepts from Biomolecules. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations.
