24- ……. is from derivative lipids

- ……….. are used to detect simple sugars.

- ……….. are used to detect lipids

 Write the scientific term

- They are huge organic molecules in living organisms which consist from hydrogen and carbon basically (such as carbohydrates, lipids, proteins and nucleic acids)

2- They are biological macromolecules formed from simple molecules (monosaccharides) which include starches, sugars and fibres. They consist of carbon, hydrogen and oxygen at ratio 1:2:1 respectively

3- They are biological macromolecules formed from carbon, hydrogen and 
oxygen atoms which include different compounds which are insoluble in water 
(but they dissolve in benzene and carbon tetrachloride)

4- They are liquid lipids formed from the reaction of unsaturated fatty acids with glycerol.

5- They are solid lipids formed from the reaction of saturated fatty acids with glycerol

6- They are formed from the reaction of fatty acids with heave molecular weights with monohydroxy alcohols (alcohols having one hydroxyl OH group.
