Language of Chemistry
- carbohydrate polyhydroxy aldehyde or ketone with a hydrogen/oxygen ratio of 2:1; all natural carbohydrates are produced by plants except glycogen.
- cholesterol steroid found in animal cells; building block of many steroidal compounds, including many hormones.
- fat triacylglyceryl ester formed by mainly saturated long chain fatty acids with glycerol; melting points of fats are generally above room temperature.
- fatty acid long chain carboxylic acid that may be saturated or have varying degrees of unsaturation.
- glycerol triol with the formula C3H8O3 that forms the "backbone" of fats and oils; since three fatty acid residues are bonded by ester linkages in fats and oils, these compounds are called triglycerides.
- lipid group of fat-soluble compounds that includes fats, oils, waxes, phosphatides, cerebrosides, and terpenoids (of which steroids are a subclass).
- minerals dietary inorganic elements that play an essential role in certain body functions; some are present in fairly large quantities and some are present in trace amounts.
- oil triacyclglyceryl ester formed by mainly unsaturated long chain fatty acids with glycerol; melting points of oils are generally below room temperature.
- protein macromolecule composed principally of long chains of amino acids.
- saturated term describing organic compounds with only carbon-carbon single bonds.
- unsaturated term describing organic compounds with double and/or triple carbon-carbon bonds.
- vitamin organic compound essential for the growth and survival of an organism but that the organism cannot synthesize for itself.
