that temperature. The behaviour of sterol ketones was similar, but the temperature
limit was slightly higher. The various levels of the sterols extracted are tabulated;
4-methylsterols had a high stability towards thermal degradation under the conditions used.
8.3.4 Unsubstituted and hydroxy substituted fatty acids
Mendoza et al [51] determined these compounds in a 5 mol 1
−1 lacustrine sediment
core taken in Leman Lake. Unbound and tightly bound compounds were not converted
from one form to another. The abundance profiles below 30 cm were not only similar
but showed no decreasing trend, suggesting a common origin in three forms. The
presence of un-substituted monounsaturated acids in the C 20 –C 32 range suggested a
possible origins for long chain fatty acids other than from higher plants. Nothing
was known of the origins of (omega-1)-hydroxy acids longer than C 20 or those of
2-methylnonacosanoic acid.
