Sorbitan is produced by the dehydration of sorbitol and is an intermediate in the conversion of sorbitol to isosorbide.The dehydration reaction usually produces sorbitan as a mixture of five- and six-membered cyclic ethers (1,4-anhydrosorbitol, 1,5-anhydrosorbitol and 1,4,3,6-dianhydrosorbitol) [3] with the five-membered 1,4-anhydrosorbitol form being the dominant product.
Sorbitol (/ ˈ s ɔː (r) b ɪ t ɒ l /), less commonly known as glucitol (/ ˈ ɡ l uː s ɪ t ɒ l /), is a sugar alcohol with a sweet taste which the human body metabolizes slowly. It can be obtained by reduction of glucose, which changes the converted aldehyde group (−CHO) to a primary alcohol group (−CH 2 OH).
The following enzymes/hormones are produced in the duodenum: secretin: This is an endocrine hormone produced by the duodenal "S cells" in response to the acidity of the gastric chyme. Cholecystokinin (CCK) is a unique peptide released by the duodenal "I cells" in response to chyme containing high fat or protein content.
Parts-per-million cube of relative abundance by mass of elements in an average adult human body down to 1 ppm. About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium ...
The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder). Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body.
BodyParts3D polygon data are extracted from full-body MRI images. The MRI image set that BodyParts3D is based on is called "TARO". Taro is a common given name for males in Japanese, as John is in English. TARO is a 2mm * 2mm * 2mm voxel dataset of the human male created by the National Institute of Information and Communications Technology. [4]
Human anatomy is the study of the shape and form of the human body. The human body has four limbs (two arms and two legs), a head and a neck , which connect to the torso . The body's shape is determined by a strong skeleton made of bone and cartilage , surrounded by fat ( adipose tissue ), muscle, connective tissue , organs, and other structures.
Superficial anatomy of female and male human body Surface projections of the major organs of the trunk, using the vertebral column and rib cage as main reference points of superficial anatomy Superficial anatomy or surface anatomy is important in human anatomy being the study of anatomical landmarks that can be readily identified from the ...
