Globules of fat are emulsified in the duodenum into smaller droplets by bile salts during food digestion, speeding up the rate of digestion by the enzyme lipase at a later point in digestion. Bile salts possess detergent properties that allow them to emulsify fat globules into smaller emulsion droplets, and then into even smaller micelles. This ...
A lipoma is a benign tumor made of fat tissue. [1] ... The mass is composed of lobules of mature white adipose tissue divided by fibrous septa containing thin-walled ...
This trilayer is collectively known as MFGM. While MFGM makes up only an estimated 2% to 6% of the total milk fat globule, [1] it is an especially rich phospholipid source, accounting for the majority of total milk phospholipids. [10] [11] In contrast, the inner core of the milk fat globule is composed predominantly of triacylglycerols.
Adipose tissue (also known as body fat or simply fat) is a loose connective tissue composed mostly of adipocytes. [1] [2] It also contains the stromal vascular fraction (SVF) of cells including preadipocytes, fibroblasts, vascular endothelial cells and a variety of immune cells such as adipose tissue macrophages.
A typical fat cell is 0.1 um in diameter [2] with some being twice that size, and others half that size. However, these numerical estimates of fat cell size depend largely on the measurement method and the location of the adipose tissue. [2] The fat stored is in a semi-liquid state, and is composed primarily of triglycerides, and cholesteryl ester.
Brown fat cells come from the middle embryo layer, mesoderm, also the source of myocytes (muscle cells), adipocytes, and chondrocytes (cartilage cells). The classic population of brown fat cells and muscle cells both seem to be derived from the same population of stem cells in the mesoderm, paraxial mesoderm.
Note the 3.6 cm (1.4 inches) of subcutaneous fat on the obese person. Subcutaneous fat is the most widely distributed subcutaneous tissue layer. [1] It is composed of adipocytes, which are grouped together in lobules separated by connective tissue. [5]
Hepatic stellate cells (HSC), also known as perisinusoidal cells or Ito cells (earlier lipocytes or fat-storing cells), are pericytes found in the perisinusoidal space of the liver, also known as the space of Disse (a small area between the sinusoids and hepatocytes).
