Metabolisme lipid

These two acetyl CoA molecules are then processed through the Krebs cycle to generate energy Figure 5. Jenis metabolisme tersebut adalah Katabolisme dan anabolisme. One of these regions is homologous with plasminogen and is thought to competitively inhibit fibrinolysis and thus predispose to thrombus.

LCAT -- it transfers acetyl groups from phosphatidylcholine to cholesterol, in order to form cholesteryl esters.

Metabolism

Di sisi lain, jika kebutuhan energi sudah mencukupi, asetil KoA dapat mengalami lipogenesis menjadi asam lemak dan selanjutnya dapat disimpan sebagai trigliserida. Setelah itu kilomikron akan ditransportasikan menuju hati dan jaringan adipose.

Perbandingan komposisi penyusun 4 klas besar lipoprotein 1. Liver sends out an "empty" HDL particle which makes its way to target tissues, where it picks up cholesterol. The majority of lipid digestion and metabolisme lipid, however, occurs once the fats reach the small intestines. Seperti halnya karbohidrat dan protein, lemak juga bias digunakan sebagai sumber energy bahkan lemak pada hewan digunakan sebagai penyimpanan energy yang sewaktu-waktu bias digunakan.

Activated fatty acids are then transported from cytosol to the mitochondrial matrix with the help of carnitine transporter. Anabolism involves three basic stages. Membrane lipid biosynthesis[ edit ] There are two major classes of membrane lipids: In the cytosol of epithelial cells, triglycerides and cholesterol are packaged into bigger particles called chylomicrons which are amphipathic structures that transport digested lipids.

Karena pada umumnya asam lemak memiliki banyak atom C, maka asil-KoA yang masih ada akan mengalami oksidasi beta kembali dan kehilangan lagi 2 atom C karena membentuk asetil KoA.

However, the main steps of fatty acids catabolism occur in the mitochondria. They are also used for energy. Ketone bodies are made from fatty acids in the liver.

The chylomicrons enable fats and cholesterol to move within the aqueous environment of your lymphatic and circulatory systems. Asam-asam lemak rantai pendek juga dapat melalui jalur ini.

Once absorbed into enterocytes, they are reassembled into TGs and packaged with cholesterol into chylomicrons, the largest lipoproteins. Thyroxine and Cortisol indirectly stimulate it via regulation of protein synthesis.

Lipid kompleks, terdiri atas lipoprotein dan glikolipid 4. Lipids may follow one of several pathways during metabolism.DIGESTION, ABSORPTION, AND TRANSPORT OF LIPIDS. SECONDARY BILE ACIDS AND SALTS: Bacteria in the intestine can modify bile salts by removing the 7alpha-carbon, to create a series of "secondary" bile salts.

Overview of Lipid Metabolism

Pendahuluan Secara umum senyawa yang disebut lipid biasanya di artikan sebagai suatu senyawa. Amino acids and proteins. Amino acids also contribute to cellular energy metabolism by providing a carbon source for entry into the citric acid cycle (tricarboxylic acid cycle), especially when a primary source of energy, such as glucose, is scarce, or when cells undergo metabolic stress.

Lipid Catabolism Summary. The major aspects of lipid metabolism are involved with Fatty Acid Oxidation to produce energy or the synthesis of lipids which is called Lipogenesis. Lipid metabolism is closely connected to the metabolism of carbohydrates which may be converted to fats.

Feb 04,  · Metabolisme lipid atau lemak berlangsung didalam hati atau hepar. Dilakukan oleh enzin lipase yang terdapat dalam getah usus dan getah pancreas. Lipid yang kita peroleh sebagai sumber energy utamanya ialah berasal dari lipid netral yakni trigliserid.

Hasil pencernaan lipid ialah asam 5/5(5). Oxidation of Fatty acids • Know equation for palmitate: C16H32O + O2 > CO2 + H2O • Comparison of glucose with palmitate for ATP production and energy yield • Mobilization of Triacylglycerols from adipose tissue.
