fatty acids

A large group of monobasic acids found in animals and plants. They are hydrocarbon chains and are saturated or unsaturated aliphatic compounds with an even number of carbon atoms. Chain lengths range up to nearly 30 carbon atoms. Fatty acids with more than about 8 carbon atoms in the chain occur most commonly as constituents of glycerides, phospholipids and sterols. The most abundant fatty acids are palmitic, stearic and oleic acids. Glucose and fatty acids are the two main fuel substances of the body. FATS are glyceride esters of fatty acids.

fatty acids

a range of molecules with the general formula Cn H2n+ 1COOH that occur naturally in many organisms, often combined with glycerol to form FATS. Fatty acids are of two main types: unsaturated, with at least one carbon-to-carbon double bond, and saturated, with no such bonds. The greater the proportion of unsaturated fatty acids in a fat the lower its melting point, with many unsaturated fats being liquid oils at room temperature. There is evidence that excess consumption of saturated fats can lead to hardening of the arteries (see ARTERIOSCLEROSIS), but the facts are disputed, particularly by butter manufacturers.

Unlike common triglycerides found in most infant formulas, Betapol is more like human milk fat and has most (40-70%) of its palmitic acid attached to the sn-2 position, with the sn-1 and sn-3 positions being occupied by unsaturated fatty acids. Studies have shown that Betapol can play a beneficial role in factors such as lipid absorption, energy availability, calcium absorption and stool softness in both preterm and term infants compared with other infant formulas.
