Medium-chain triglycerides MCT are a class of lipids in which three intermediate carbon length saturated fats are bound to a glycerol backbone.

. These processes can mainly be divided into 1 catabolic processes that generate energy and 2 anabolic processes where they serve as building blocks for other compounds. Lipase from the pancreas digests lipids to fatty acids and glycerol in our small intestine. However most of it comes from pancreatic juices.

The enzyme is activated in presence of hydrochloric acid and its role is to begin the digestion of protein in the stomach. Gastric peristalsis further reduces food particle size preparing macronutrients for additional chemical breakdown and absorption in the small intestine. In the stomach gastric lipase starts to break down triglycerides into diglycerides and fatty acids.

Digestion could be described as the process by which the food we eat passes through our bodies and are directed towards the purposes of providing the body with energy or building new cellular components and tissues such as muscle or fat. Along with bile these enzymes break down fats. The stomach also produces gastric lipase which plays its.

Furthermore administration of a compound that retards fat digestion by inhibiting the lipasecolipase-mediated fat hydrolysis was associated with reduced food intake and elevated concentrations of plasma CCK and enterostatin in rats Mei et al 2006. Pepsinogen is secreted by gastric glands of the stomach into the stomach. The parts of food that the body cannot use and also other wastes from the body are eliminated in the form of excrement.

The pancreas discharges a mixture of trypsin chymotrypsin carboxypeptidases α-amylase lipase and other enzymes that respectively digest proteins and peptides starches triacylglycerols and other compounds in. Triglycerides and phospholipids in conjunction with the emulsification effects of bile salts lecithin that are released from the gallbladder. About 10 of lipase comes with saliva.

Improves blood glucose control following indigestion -stored in adipose tissue. Amylase One type of amylase called ptyalin is made in the salivary glands and starts to act on starches while. Fatty acid metabolism consists of various metabolic processes involving or closely related to fatty acids a family of molecules classified within the lipid macronutrient category.

There in the acid environment of the stomach pepsinogen is converted into. Undigested carbohydrates can cause diarrhea. The pancreas also produces the hormones insulin and glucagon which regulate blood sugar levels cells that produce these two hormones make up the islets of Langerhans one of which is represented by the light-colored circular structure in the photomicrograph below.

These actions cause the fats to become more accessible to the digestive enzymes. Pepsin is a protease that begins digestion of proteins breaking them into peptides and amino acids. Lipase breaks down lipids which are fats and oils into glycerol and fatty acids.

Emulsification results in the breakdown of fats into small particles that can be readily digested with the help of lipase. As a result the fats become tiny droplets and separate from the watery components. Insulates kidneys heart other organs and storage site for fat soluble vitamins.

101MCT are distinguished from other triacylglycerols in that each fat molecule R groups in Fig. The gastrointestinal tract GI tract digestive tract alimentary canal is the tract or passageway of the digestive system that leads from the mouth to the anusThe GI tract contains all the major organs of the digestive system in humans and other animals including the esophagus stomach and intestinesFood taken in through the mouth is digested to extract nutrients and absorb. Poor absorption of fat leads to diarrhea and fatty bowel movements.

Made up of adipocytes fat cells. 101 is between six and twelve carbons in length Table 101. The enzyme ____ is the most important digestive enzyme in gastric juice.

As a result the fats become tiny droplets and separate from the watery components. Figure 510 Lipid Digestion and Absorption. In the stomach gastric lipase starts to break down triacylglycerols into diglycerides and fatty acids.

It breaks down protein in the food. The structure is called triacylglycerols or triglycerides Fig. Essential for digestion of fats eg.

Lipase from pancreatic juices and bile from the gallbladder. It helps to break down starch into sugar which is then converted to energy to meet the bodys demand. The enzymes help break down fats proteins and carbohydrates.

Therefore delaying fat digestion might be a promising method to enhance the satiating effect of fats and deserves.
