To solve this problem, we need to evaluate each statement about lipids and determine which are correct. Let's analyze each statement:$\newline \bullet$(a) Lecithin found in the plasma membrane is a glycolipid:$\newline$ - Lecithin is actually a phospholipid, not a glycolipid. It contains a phosphate group.$\newline$ - Therefore, this statement is incorrect.$\newline \bullet$(b) Saturated fatty acids possess one or more C=C bonds:$\newline$ - Saturated fatty acids do not have C=C double bonds; they have only single bonds between carbon atoms.$\newline$ - Therefore, this statement is incorrect.$\newline \bullet$(c) Gingelly oil has a lower melting point, hence remains as oil in winter:$\newline$ - Gingelly oil, like other oils, has a lower melting point due to the presence of unsaturated fatty acids.$\newline$ - This allows it to remain liquid at lower temperatures.$\newline$ - Therefore, this statement is correct.$\newline \bullet$(d) Lipids are generally insoluble in water but soluble in some organic solvents:$\newline$ - Lipids are hydrophobic and do not dissolve in water, but they are soluble in organic solvents like chloroform and ether.$\newline$ - Therefore, this statement is correct.$\newline \bullet$(e) When a fatty acid is esterified with glycerol, monoglycerides are formed:$\newline$ - When one fatty acid is esterified with glycerol, a monoglyceride is formed.$\newline$ - Therefore, this statement is correct.$\newline$Now, let's identify the correct set of statements:$\newline$The correct statements are (c), (d), and (e).$\newline$Therefore, the correct answer is Option 3: (c), (d), and (e) only.
