Long chains of Carbon Hydrogen bonds containing Carbon, Hydrogen and Oxygen (C-H-O).

• Chemical Structure of Nucleic Acids

• Chemical Structure of Carbohydrates

• Chemical Structure of Lipids

Double bond between Carbon and Hydrogen chains.

Tends to be liquid at room temperature like oils.

• Polysaccharides

• Saturated Fats

• Lipids

Trans Fatty Acids are formed due to the partial reduction of polyunsaturated oils by hydrogenation.

• True

• False

Which of the following facts is not TRUE about lipids?

• more double bonds, increase in melting point

• sparingly soluble in water but insoluble in organic solvents

• act as thermal insulators

• solubility decreases with increasing carbon chain length

Fatty Acids differ in there chain length and their

• protein carriers

• Side chains

• energy level

• degree of saturation
