(A) Lecithin found in the plasma membrane is a glycolipid.
(B) Saturated fatty acids possess one or more C=C bonds.
(C) Gingelly oil has a lower melting point; hence remains as oil in winter.
(D) Lipids are generally insoluble in water but soluble in some organic solvents.
(E) When fatty acid is esterified with glycerol, monoglycerides are formed.
Choose the correct answer from the options given below:
(A), (B), and (C) only
(A), (D), and (E) only
(C), (D), and (E) only
(A), (B), and (D) only
Lecithin is a phospholipid. Saturated fatty acids do not possess double bond
A dehydration reaction links two glucose molecules to produce maltose. If the formula for glucose is then what is the formula for maltose?
Maltose is a disaccharide made up two units of glucose with a chemical formula
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 the carboxyl carbon.
(E) Arachidonic acid has 16 carbon atoms.

(B) and (E) only
(A) and (B) only
(C) and (D) only
(B) and (C) only
Unsaturated fatty acids contain one or more double C=Cbonds. Palmitic acids and arachidonic acid has 16 and 20 carbons respectively including carboxyl carbon.

Carbohydrates (commonly called sugars) are chemically defined as polyhydroxy aldehyde or ketones. All sugar molecules have one carbonyl group (-CO-) in addition to hydroxyl group (OH) on other carbon atoms.
A typical fat molecule is made up of
one glycerol and one fatty acid molecule
three glycerol and three fatty acid molecules
three glycerol molecules and one fatty acid molecule
one glycerol and three fatty acid molecules
Neutral or true fats are triglycerides which are formed by esterification of three molecules of fatty acids with one molecule of trihydric alcohol, glycerol (glycerine or trihydroxy propane)
