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.
