Lipid - Waxes, Fatty Acids, Esters | Britannica
网页2024年9月20日 · Lipid - Waxes, Fatty Acids, Esters: A second group of neutral lipids that are of physiological importance, though they are a minor component of biological systems, are waxes. Essentially, waxes consist of a long-chain fatty acid linked through an ester oxygen to a long-chain alcohol.
Wax - Wikipedia
网页Waxes are a diverse class of organic compounds that are lipophilic, malleable solids near ambient temperatures. They include higher alkanes and lipids , typically with melting points above about 40 °C (104 °F), melting to give low viscosity liquids.
