Lipids

Not quite remember

I easily remember

Elements of lipids

1) Carbon, hydrogen and oxygen 2) Has higher ratio of hydrogen atoms to oxygen atoms

Types of lipids

Fats, waxes, phospholipids and steroids

Triglycerides

1) An ester formed from the process of condensation of one molecule of glycerol with three molecules of fatty acids 2) Examples of triglycerides are fats and oils

Types of fatty acids

Saturated fats and unsaturated fats

Similarities between saturated fats and unsaturated fats

Both contain the elements of carbon, hydrogen, oxygen, glycerol, fatty acids, and are non-polar molecules

Characteristics of saturated fats

Fatty acids have a single bond between carbons, have no addition of hydrogen atoms, exist in solid form at room temperature. For example, butter and animal fats

Characteristics of unsaturated fats

Fatty acids that have at least one double bond between the carbons, the double bond can still accept the addition of hydrogen, exist in liquid form at room temperature

Waxes

Contains one molecule of alcohol that combines with another molecule of fatty acid and is waterproof

Phospholipids

The main component of the plasma membrane that made up of one molecule of glycerol, two molecules of fatty acids, and one group of phosphate

Steroids

Is a type of lipid that does not have fatty acids. Examples: cholesterol, testosterone, estrogen, and progesterone
