Lipid metabolism is the synthesis and degradation of lipids in cells, involving the breakdown or storage of fats for energy and the synthesis of structural and functional lipids, such as those involved in the construction of cell membranes. In animals, these fats are obtained from food or are synthesized by the liver. Lipid metabolism is often considered as the digestion and absorption process of dietary fat; however, there are two sources of fats that organisms can use to obtain energy: from consumed dietary fats and from stored fat.

NCBI Bookshelf. Endotext [Internet]. Cholesterol and triglycerides are insoluble in water and therefore these lipids must be transported in association with proteins. Lipoproteins are complex particles with a central core containing cholesterol esters and triglycerides surrounded by free cholesterol, phospholipids, and apolipoproteins, which facilitate lipoprotein formation and function. Apolipoproteins have four major functions including 1 serving a structural role, 2 acting as ligands for lipoprotein receptors, 3 guiding the formation of lipoproteins, and 4 serving as activators or inhibitors of enzymes involved in the metabolism of lipoproteins.

Lipids are large molecules and generally are not water-soluble. Like carbohydrates and protein , lipids are broken into small components for absorption. Since most of our digestive enzymes are water -based, how does the body break down fat and make it available for the various functions it must perform in the human body? The first step in the digestion of triglycerides and phospholipids begins in the mouth as lipids encounter saliva. Next, the physical action of chewing coupled with the action of emulsifiers enables the digestive enzymes to do their tasks.

Digestion and Absorption of Lipids

Digestion is the chemical breakdown of the ingested food into absorbable molecules. Absorption refers to the movement of nutrients, water and electrolytes from the lumen of the small intestine into the cell, then into the blood. In this article, we will look at the digestion and absorption of carbohydrates, protein and lipids. There are three carbohydrate products which are absorbed by the small intestine; glucose , galactose and fructose. Digestion of starch is initiated in the mouth, facilitated by salivary amylase.

Тебе это отлично известно. Она пожала плечами: - Быть может, Стратмору не хотелось задерживаться здесь вчера вечером для подготовки отчета. Он же знал, что Фонтейн в отъезде, и решил уйти пораньше и отправиться на рыбалку. - Да будет тебе, Мидж.  - Бринкерхофф посмотрел на нее осуждающе.  - Дай парню передохнуть.

Я звоню Джаббе.
