saturated fat,

any solid fat that is an esterester,
any one of a group of organic compounds with general formula RCO2R′ (where R and R′ are alkyl groups or aryl groups) that are formed by the reaction between an alcohol and an acid.

 and a saturated fatty acidfatty acid,
any of the organic carboxylic acids present in fats and oils as esters of glycerol. Molecular weights of fatty acids vary over a wide range. The carbon skeleton of any fatty acid is unbranched. Some fatty acids are saturated, i.e.

. The molecules of a saturated fat have only single bonds between carbon atoms; if double bonds are present in the fatty acid portion of the molecule, the fat is said to be unsaturated. Unsaturated fats generally have lower melting points than saturated fats and are often liquids (oils) at room temperature. Unsaturated fats can be converted to saturated fats by a process called hydrogenation; since this usually raises the melting point of the fat and makes it a solid, the process is also called hardening. A correlation has been found between the consumption of solid fats in food and cholesterol levels in blood. Cholesterol forms arterial plaques that may lead to blockage of the arteries, i.e., atherosclerosis. Dietary guidelines in the United States call for reduced intake of saturated fat. See fats and oilsfats and oils,
group of organic substances that form an important part of the diet and also are useful in many industries. The fats are usually solid, the oils generally liquid at ordinary room temperatures.

The behavior of saturated fatty acids once they've entered cells contributes to major and often deadly diseases," Min said.
Previous research showed that there was a positive correlation between the ratio of unsaturated to saturated fatty acids and the energy values of oils [9,10], and the DE and ME values increased as the ratio of unsaturated to saturated fatty acids increased.

It contains saturated fat, of course, but it contains other nutrients and some unique saturated fatty acids, and the whole dairy package appears to have a neutral, or in fact, a protective effect on heart disease, type 2 diabetes and obesity.
Nutritionists advise that the contribution of calories from fats and oils in the energy regime should not exceed 30% of the total requirement; also the contribution of saturated fatty acids should be less than 10%.
1997) commented that this enzyme is responsible for the desaturation of saturated fatty acids with 16 and 18-carbon, converting them into their corresponding monounsaturated forms, by adding a double bond at the carbon 9.
The study looked at how high-saturated-fat, low-carb diets and high-carb, low-saturated-fat diets affect blood levels of saturated fatty acid (known to lead to cardiovascular disease) and an omega-7 fatty acid called palmitoleic acid.
She added: "These odd-chain saturated fatty acids are well-established markers of eating dairy fats, which is consistent with several recent studies, including our own, that have indicated a protective effect against type-2 diabetes from eating yoghurt and other dairy products.
8Trans fatty acids and cardiovascular disease: As the adverse effects of dietary saturated fatty acids became known TFA were considered to be a safe replacement of butter fat.
There has been an increasing number of reports about edible oil organogels as potential alternatives to solid fats containing trans fatty acids and a high content of saturated fatty acids.
It is loaded with beneficial medium-chain saturated fatty acids that cannot be oxidized.
