Initially, these lipid droplets were considered to merely serve as fat depots, but since the discovery in the 1990s of proteins in the lipid droplet coat that regulate lipid droplet dynamics and lipid metabolism, lipid droplets are seen as highly dynamic organelles that play a very important role in the regulation of intracellular lipid storage ...
The final branch which is important for the digestive system is the inferior mesenteric artery, which supplies the regions of the digestive tract derived from the hindgut, which includes the distal 1/3 of the transverse colon, descending colon, sigmoid colon, rectum, and the anus above the pectinate line.
aids in the digestion of fats [1] pancreatic lipase: PNLIP: digestive juice: Human pancreatic lipase (HPL) is the main enzyme that breaks down dietary fats in the human digestive system. [5] To exhibit optimal enzyme activity in the gut lumen, PL requires another protein, colipase, which is also secreted by the pancreas. [18] lysosomal lipase: LIPA
In addition the lymph which drains the small intestine contains fat droplets called chylomicrons after the ingestion of a fatty meal. [28] This lymph is called chyle which has a milky appearance, and imparts the name lacteals (referring to the milky appearance of their contents) to the lymph vessels of the small intestine.
In cellular metabolism, unsaturated fat molecules yield slightly less energy (i.e., fewer calories) than an equivalent amount of saturated fat. The heats of combustion of saturated, mono-, di-, and tri-unsaturated 18-carbon fatty acid esters have been measured as 2859, 2828, 2794, and 2750 kcal/mol, respectively; or, on a weight basis, 10.75 ...
The primary way of managing the symptoms of lactose intolerance is to limit the intake of lactose to a level that can be tolerated. [47] Lactase deficient individuals vary in the amount of lactose they can tolerate, [ 1 ] and some report that their tolerance varies over time, depending on health status and pregnancy.
Lipids are the only class of macromolecules that are not made up of polymers. They include steroids, phospholipids, and fats, [37] largely nonpolar and hydrophobic (water-repelling) substances. [39] Proteins are the most diverse of the macromolecules. They include enzymes, transport proteins, large signaling molecules, antibodies, and ...
In biology, autolysis, more commonly known as self-digestion, refers to the destruction of a cell through the action of its own enzymes. It may also refer to the digestion of an enzyme by another molecule of the same enzyme. The term derives from the Greek αὐτο- 'self' and λύσις 'splitting'.
