what are the types of enzymes in digestion that split fatty acids?
lipases
triglyceride digestion by endogenous lipases leads to hydrolysis of fatty acids from the triacylglyceride sn-1,3 positions, to release two fatty acids and one sn-2 monoglyceride into the intestinal lumen. the fatty acids configuration on the triglyceride has a major contribution to the efficacy of this nutrient absorption. while the unsaturated and short chain saturated free fatty acids are well absorbed regardless of their position, the absorption of free long chain saturated fatty acids, i.e. palmitic acid and longer, is relatively low. the main cause for this low absorption is their melting point above body temperature (~630 c), and thus high tendency to create complexes with dietary minerals, such as calcium or magnesium which are secreted into feces leading to loss of both fatty acids (energy) and calcium. these complexes, also known as fatty acids soaps, are insoluble and therefore indigestible and positively related to stool hardness.

bullet::::- long-chain fatty acids (lcfa) are fatty acids with aliphatic tails of 13 to 21 carbons.









































bullet::::- very long chain fatty acids (vlcfa) are fatty acids with aliphatic tails of 22 or more carbons.









































section::::types of fatty acids.:saturated fatty acids.









































saturated fatty acids have no c=c double bonds. they have the same formula ch(ch)cooh, with variations in "n". an important saturated fatty acid is stearic acid (n = 16), which when neutralized with lye is the most common form of soap.
