(or triacylglycerol) that is an ester of fatty acids
. Each fat molecule contains one glycerol residue connected by ester linkages to three fatty acid residues, which may be the same or different. The fatty acids may have no double bonds in the carbon chain (saturated fatty acids), one double bond (monounsaturated), or two or more double bonds (polyunsaturated). Essential fatty acids cannot be synthesized by the body but must be obtained from the diet or from intravenous infusion of lipids.
Saturated and Unsaturated Fats. All of the common unsaturated fatty acids are liquid (oils) at room temperature. Through the process of hydrogenation, hydrogen can be incorporated into certain unsaturated fatty acids so that they are converted into solid fats for cooking purposes. Margarine is an example of the hydrogenation of unsaturated fatty acids into a solid substance.
a thermogenic type of adipose tissue containing a dark pigment, and arising during embryonic life in certain specific areas in many mammals, including humans (see illustration); it is prominent in the newborn. Called also brown adipose tissue

sat·u·rat·ed fat·ty ac·id
a fatty acid, the carbon chain of which contains no ethylenic or other unsaturated linkages between carbon atoms (for example, stearic acid and palmitic acid); called saturated because it is incapable of absorbing any more hydrogen.

Any of various fats, including most animal fats, coconut oil, and palm oil, that are solid at room temperature and whose fatty acid chains cannot incorporate additional hydrogen atoms. An excess of these fats in the diet is associated with high cholesterol levels in the bloodstream.

Patient discussion about saturated fat
Q. I am wondering if any of you are ENTHUSED about the use of COCONUT OIL. I ask because it IS SATURATED FAT. I have trouble losing weight. That inculdes getting cold frequently, and was wondering if cocounut oil would help me maintain body temperture more easily. Also, I have notice that SOME claim that coconut oil has many health benefits not affiliated with polyunsaturates.
A. i know there was a Polynesian research about people that consume coconut oil on a daily basis in parallel to people who don't. they found out that there are high cholesterol levels among the people that consumed coconut oil but no significant difference in heart problems.More discussions about saturated fat
