A fatty acid in which carbon is joined with four other atoms; i.e., all carbon atoms are bound to the maximum possible number of hydrogen atoms. A saturated fat is composed of triglycerides in which most of the fatty acids are saturated.
A fatty acid that has the maximum possible number of hydrogen atoms attached to every carbon atom. It is said to be "saturated" with hydrogen atoms. Saturated fatty acids are mostly found in animal products such as meat and whole milk. Saturated fat: A fat made of saturated fatty acids. Butter and lard are saturated fats. Saturated fats tend to raise levels of LDL- cholesterol ("bad" cholesterol) in the blood. Elevated levels of LDL-cholesterol are associated with heart disease.
A fatty acid, the carbon chain of which contains no ethylenic or other unsaturated linkages between carbon atoms (e.g., stearic acid and palmitic acid); called saturated because it is incapable of absorbing any more hydrogen.
