lipid is an water insoluble biochemical molecule, but it is soluble in nonpolar solvent
Lipids are naturally occurring organic compounds, commonly known as oils and fats
lipids are relatively insoluble in water, but they are freely soluble in organic solvents like ether, acetone and benzene
lipids are used as storage compounds, triglycerides serve as reserve energy for the body
fats and oils
they also called triacylglycerols or triglycerides, and they are glycerol triesters
they are carboxylic acids with long chain hydrocarbon chains
they can either be saturated or unsaturated.
saturated fatty acids can pack more tightly, and remain in solid form at room temperature.
Unsaturated fatty acids are not as tightly packed as saturated fatty acids and are liquid at room temperature.
Micelle, where the polar region is the outer side of the sphere and the non-polar region forms the center of the sphere.
a carboxyl group
Hydrogenation is the adding of hydrogen atoms to unsaturated fatty acids. This makes the liquid fats more solid. This process is used to make margarine
it is a saturated fatty acid with 18 carbons in the chain
it is unsaturated fatty acid with 18 carbons in the chain
it is when the hydrogens are on the same side of the double bond, they are naturally occuring
it is when the hydrogens are on opposite sides of the double bond, they are normally linear and occur in partially hydrogenated foods
by the bonding of fatty acids and a glycerol molecule
Glycerol is a 3 carbon alcohol that is used to form triglycerides
by hydrolysis or dehydration
they are similar to triglycerides but contain a phosphate group and a choline in place of the fatty acid
the 3rd hydroxyl group of glycerol is linked to a phosphate group
sterols are lipids that contain many rings of carbon atoms.
