Oils can be converted to oils by
Hydrogenation
Amino acids have which functional groups?
Amide and Carboxyl
Hydrolysis of proteins produces
Amino acids
How are soaps formed?
By the Alkaline hydrolysis of fats and oils
Emulsifiers are made up of
Fatty acids and hydroxyl groups
Emulsifiers are made by reacting
Edible oils and glycerol
The most common compounds found in terpenes are
Essential oils
Products formed by terpene oxidation in plants are responsible for the
Aroma of spice molecules
How do free radical scavengers work?
When the esters are applied to skin they hydrolyse to produce a vitamin which is absorbed and stops free radicals seeping into the skin
Essential oils are
Concentrated extracts of the aroma compound found in plants
When protein become denatured which bonds break?
Hydrogen
What is an aroma molecule?
Something which has a smell and tends to be an aldehyde
Why to detergents not form a precipitate?
Because they contain sulohonate ions instead of just carboxylate ions and these do not react with ions on water.
The alkaline hydrolysis of fats and oils produces
Glycerol and a salt (soup)
Hydrogenation
The addition of hydrogen across a double bond
Evidence that an ester has formed
Oily immiscible layer
Distinct smell
Catalysed by concentrated sulphuric acid
Bond enthalpy
The energy required to break a bond to produce free atoms in the gas phase
Feed stock
A reactant form in which other chemicals can be extracted or synthesised to manufacture a specific product (Raw material is the original source of feedstock)
