lipids
what are the five main categories of lipids
fatty acids, Fats/triglycerides, phospholipids, steroids, waxes
what is a lipid
it's a general term for a variety of nonpolar biological molecules that are hydrophobic made up of carbon hydrogen and oxygen atoms
how can you tell if you're looking at a fatty acid
it's a chain of hydrocarbons that ends with a carboxyl group
how to tell if a fatty acid is saturated or not
if it's saturated it has no double bonds between carbons
how can you tell if a fatty acid is unsaturated
if there is one or more double bonds between carbon atoms a fatty acid is unsaturated
what is a saturated fat
saturated fats tend to be solid in our fat from animals for example meat butter and Dairy
what is an unsaturated fat
unsaturated fats tend to be liquid fat from plants for example nuts oils and avocado
what's the importance of triglycerides
energy storage
what are triglycerides composed of
one glycerol molecule and Three fatty acid molecules are bonded by an asteroidance to form a triglyceride
what's phospholipids used for
the main component of cell membranes
describe the body of a phospholipid
it has a phosphate and which is considered the head and a fatty acid chain tail the head is polar and carries a slightly negative charge and is hydrophilic as the tail is nonpolar and hydrophobic
what are steroids composed of
four carbon-based rings attached to each other
where are steroids present
cholesterol is an example of steroids in the body and is a component of cell membranes present in Blood of animals and is a part of some sex hormones like testosterone and estrogen
can cholesterol be bad
yes if you have two high cholesterol levels in blood it can cause it to build up in the lining of the blood vessels
what is a wax composed of
it's a long carbon-based chain that is solid at room temperature
how are wax is produced
it is produced both in Plants by the coats of the leaves and an animals as a water repellent coating on skin for feathers and bees produce beeswax
