зберігаються в організмі у вигляді тригліцеридів, є важливим джерелом енергії.

Енергетичний вихід з 1 г ЖК складає ~ 9 ккал (37 кДж), а з 1 г вуглеводів 4 ккал (17 кДж).

Fatty acids are usually ingested as triglycerides, which cannot be absorbed by the intestine.

They are broken down into free fatty acids and monoglycerides by pancreatic lipase, which forms a 1:1 complex with a protein called colipase, which is necessary for its activity.

The activated complex can work only at a waterfat interface.

Therefore, it is essential that fatty acids (FA) be emulsified by bile salts for optimal activity of these enzymes.

People having had their gallbladder removed due to gall stones have, as a consequence, great difficulty digesting fats.

Pancreatic lipase, also known as pancreatic triacylglycerol lipase, is secreted from the pancreas, and is the primary lipase (enzyme) that hydrolyzes (breaks down) dietary fat molecules in the human digestive system, converting triglyceride substrates found in ingested oils to monoglycerides and free fatty acids.

Triacylglycerol + H2O  diacylglycerol + a fatty acid anion

Процес розщеплення триацилгліцеролів із вивільненням жирних кислот, які виходять у кров, називається мобілізацією ЖК із жирової тканини
