Campesterol

Campesterol is a phytosterol, meaning it is a steroid derived from plants. As a food additive, phytosterols have cholesterol-lowering properties (reducing cholesterol absorption in intestines), and may act in cancer prevention. Phytosterols naturally occur in small amount in vegetable oils, especially soybean oil. One such phytosterol complex, isolated from vegetable oil, is cholestatin, composed of campesterol, stigmasterol, and brassicasterol, and is marketed as a dietary supplement. Sterols can reduce cholesterol in human subjects by up to 15\\\\\%. The mechanism behind phytosterols and the lowering of cholesterol occurs as follows : the incorporation of cholesterol into micelles in the gastrointestinal tract is inhibited, decreasing the overall amount of cholesterol absorbed. This may in turn help to control body total cholesterol levels, as well as modify HDL, LDL and TAG levels. Many margarines, butters, breakfast cereals and spreads are now enriched with phytosterols and marketed towards people with high cholesterol and a wish to lower it. -- Wikipedia. Campesterol is a member of phytosterols, a 3beta-sterol, a 3beta-hydroxy-Delta(5)-steroid and a C28-steroid. It has a role as a mouse metabolite. It derives from a hydride of a campestane. Campesterol is a natural product found in Haplophyllum bucharicum, Bugula neritina, and other organisms with data available. Campesterol is a steroid derivative that is the simplest sterol, characterized by the hydroxyl group in position C-3 of the steroid skeleton, and saturated bonds throughout the sterol structure, with the exception of the 5-6 double bond in the B ring.

Maltotriose

C18H32O16 (504.169)


Maltotriose is a trisaccharide (three-part sugar) consisting of three glucose molecules linked with α-1,4 glycosidic bonds. It is most commonly produced by the digestive enzyme alpha-amylase (a common enzyme in human saliva) on amylose in starch. The creation of both maltotriose and maltose during this process is due to the random manner in which alpha amylase hydrolyses α-1,4 glycosidic bonds. It is the shortest chain oligosaccharide that can be classified as maltodextrin. Maltotriose belongs to the class of organic compounds known as oligosaccharides. These are carbohydrates made up of 3 to 10 monosaccharide units linked to each other through glycosidic bonds. Maltotriose is a common oligosaccharide metabolite found in human urine after maltose ingestion or infusion (PMID:6645121). Maltotriose is increased in glycogen storage disease II (OMIM: 232300) due to a mutation of the enzyme alpha-1,4-glucosidase (EC 3.2.1.20) (PMID:4286143). Constituent of corn syrup.
