WebWaxes 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. These molecules are completely water-insoluble and generally solid at biological temperatures. WebCarbon dating is a method of determining the age of an organic material with the help of radiocarbon (also known as isotopic chronometer). This carbon 14 isotope is one of the weakest radioactive isotopes of carbon which is used in this method. Accelerator mass spectrometry and gas proportional counting are the two types of carbon dating.
