Introduction to lipids
Lipids are a diverse group of compounds that are insoluble
in water but soluble in organic solvents such as ethanol.
The most common types
of lipid are triglycerides
(sometimes known as true
fats or neutral fats), but
other important lipids
include waxes, steroids
and cholesterol.
Like carbohydrates, lipids contain carbon, hydrogen and
oxygen, but they have a higher proportion of hydrogen and
a lower proportion of oxygen.
