A nucleoside is :
1 base + sugar
2 base + phosphate
3 sugar + phosphate
4 base + sugar + phosphate
Explanation:
Exp: A A nucleoside consist of a base and sugar. A Nitrogenous base is a nitrogen containing compound that may form a nucleoside when they are attached to five carbon sugar ribose or deoxyribose.

Which of the following is/are essential fatty acids for man?
1 Arachidonic acid
2 Linolenic acid
3 Linoleic acid
4 All of these
Explanation:
Exp: D The two essential fatty acids in the human body are alpha-linolenic acid and linoleic acid. Omega6 polyunsaturated fatty acid is arachidonic acid. It is found in phospholipids and contributes to membrane formation. The conversion of linoleic acid into arachidonic acid is not an essential amino acid. Arachidonic acid is a polyunsaturated omega- 6 fatty acid. It is present in the phospholipids and helps in the formation of membranes.

Following are the statements with reference to 'lipids'
1 (B) and (E) only
2 (A) and (B) only
3 (C) and (D) only
4 (B) and (C) only
5 Arachidonic acid has 16 carbon atoms. Choose the correct answer from the options given below.
Explanation:
Exp: D Lecithin is phospholipid, lecithin is a generic term to designate any group of yellow-brownish fatty substances occuring in animal and plant tissues which are amphiphilic, they attract both water and fatty substances and are used for smoothing food textures, emulsifying. - Glycerol is a simple trihydroxy propane lipid. Glycerol sometimes called glycerin is a chemical molecule that is commonly used to treat burns and wounds.

Which one of the following is INCORRECT about saturated fatty acids ?
1 They do not have double bond between carbon atoms.
2 They are not fully saturated with hydrogen atoms.
3 Palmitic acid and stearic acid are saturated fatty acids.
4 They contain maximum possible hydrogen atoms.
Explanation:
Exp: B When there are only single bonds between the neighboring carbons in the hydrocarbon chain, a fatty acid is said to be saturated. Fatty acid are saturated with the hydrogen. Hence, they are not fully saturated with hydrogen atoms. This statement is incorrect about saturated fatty acid.
Exp: A A nucleoside consist of a base and sugar. A Nitrogenous base is a nitrogen containing compound that may form a nucleoside when they are attached to five carbon sugar ribose or deoxyribose.
