Oils and Fats (6)

Not quite remember

I easily remember

Structure of saturated fatty acid

Structure of unsaturated fatty acids

The effect of the presence of double bonds on unsaturated fats (1)

Causes unsaturated fats to have low melting points

The effect of the presence of double bonds on unsaturated fats (2)

Causes unsaturated fats to have exist as liquids

Conversion of unsaturated fats to saturated fats through hydrogenation reaction (1)

Oils consist of a high percentage of unsaturated fats

Conversion of unsaturated fats to saturated fats through hydrogenation reaction (2)

Unsaturated fats are converted into saturated fats through hydrogenation reaction

Conversion of unsaturated fats to saturated fats through hydrogenation reaction (3)

During a hydrogenation reaction, hydrogen gas, H2 is passed into hot oil with the presence of nickel, Ni as the catalyst

Conversion of unsaturated fats to saturated fats through hydrogenation reaction (4)

The double bond in the carbon chain is “opened” and the hydrogen atoms, H are added to the carbon chain

Conversion of unsaturated fats to saturated fats through hydrogenation reaction (6)

The addition of hydrogen atoms to the carbon chain causes the molecular mass to increase that leads to the increase in the melting point and boiling point
