Resource summary

Lipids, Triglycerides and Phosphlipids
1 LIPIDS
1.1 Made up of Carbon, Hydrogen and Oxygen but in much more higher proportions of hydrogen than carbohydrates.
1.2 The most common lipid is triglyceride
1.3 At room temperature, fats are soild and oils are liquid.
2 TRIGLYCERIDES
2.1 3 fatty acids chains are attached to a glycerol
2.1.1 Fatty acids are acids because they contain the -COOH which is a carboxyl group.
2.2 A glycerol molecule has 3 carbons in which the -OH of the triglyceride attaches to the -H of the glyercol, this reaction is a condensation reaction because it makes 3 waters.
2.2.1 The bond between the fatty acid chain and the glycerole molecule is called an ester linkage
2.3 Insoluble in water because they are hydrophobic, their charge isn't attracted to water
3 SATURATED/UNSATURATED
3.1 Fatty acids are saturated because they have one single carbon bond
3.1.1 These are solid at room temperature.
3.2 If one or more bonds between the carbon atoms have double bonds, then it is said to be unsaturated
3.2.1 Usually liquid at room temperature.
