A hydrophobic macromolecule made mainly from carbon and hydrogen atoms; includes fats, oils, and waxes
How is a fat molecule made?
A fat molecule is constructed when the carboxyl groups of the three fatty acids molecules bond with the hydroxyl groups of the three carbon glycerol alcohol by an ester linkage. The fat is called triglyceride.
Three-carbon alcohol with three hydroxyl groups; component of fats and oils.
A long carbon chain with an attached carboxyl group attached to the end and a hydrocarbon chain attached to the carboxyl group. It is this hydrocarbon chain which gives the fatty acid a hydrophobic nature.
A Bond between hydroxyl and carboxyl grp, joining glycerol and fatty acids together → dehydration rxn
3 fatty acids (chains of hydrocarbons) bonded to a glycerol, most fats are eaten and absorbed in this form, carbohydrate
fatty acid chains lacking double bonds; therefore, the chains pack tightly, are solid at room temp and bad fats, major source is animals
Fats that contain one or more double bonds between carbon atoms and have less than the maximum number of hydrogen atoms bonded to carbon
artificial fat made from the process of hydrogenation; believed to increase a person's risk for coronary artery disease
A molecule that is a constituent of the inner bilayer of biological membranes, having a polar, hydrophilic head and a hydrophobic tail.
A type of lipid characterized by a carbon skeleton consisting of four rings.
a steroid that forms an essential component of animal cell membranes and acts as a precursor molecule for the synthesis of other biologically important steroids, such as hormones.
