Cellulose occurs naturally in some foods and is an additive in manufactured foods, contributing an indigestible component used for texture and bulk, potentially aiding in defecation. [ 70 ] Building material: Hydroxyl bonding of cellulose in water produces a sprayable, moldable material as an alternative to the use of plastics and resins.
Cellulase. Cellulase (EC 3.2.1.4; systematic name 4-β-D-glucan 4-glucanohydrolase) is any of several enzymes produced chiefly by fungi, bacteria, and protozoans that catalyze cellulolysis, the decomposition of cellulose and of some related polysaccharides: The name is also used for any naturally occurring mixture or complex of various such ...
Cellulose is a polymer made with repeated glucose units bonded together by beta-linkages. Humans and many animals lack an enzyme to break the beta-linkages, so they do not digest cellulose. Certain animals, such as termites can digest cellulose, because bacteria possessing the enzyme are present in their gut. Cellulose is insoluble in water.
Cellulose fiber. Appearance. Cellulose fibers (/ ˈsɛljʊloʊs, - loʊz /) [ 1 ] are fibers made with ethers or esters of cellulose, which can be obtained from the bark, wood or leaves of plants, or from other plant-based material. In addition to cellulose, the fibers may also contain hemicellulose and lignin, with different percentages of ...
Foods rich in fibers: fruits, vegetables and grains. Wheat bran has a high content of dietary fiber. Dietary fiber (fibre in Commonwealth English) or roughage is the portion of plant-derived food that cannot be completely broken down by human digestive enzymes. [ 1 ] Dietary fibers are diverse in chemical composition and can be grouped ...
Carbohydrate metabolism is the whole of the biochemical processes responsible for the metabolic formation, breakdown, and interconversion of carbohydrates in living organisms. Carbohydrates are central to many essential metabolic pathways. [ 1 ] Plants synthesize carbohydrates from carbon dioxide and water through photosynthesis, allowing them ...
Human nutrition deals with the provision of essential nutrients in food that are necessary to support human life and good health. [1] Poor nutrition is a chronic problem often linked to poverty, food security , or a poor understanding of nutritional requirements. [ 2 ]
A specially developed strain of barley, high in resistant starch. Resistant starch (RS) is starch, including its degradation products, that escapes from digestion in the small intestine of healthy individuals. [ 1 ][ 2 ] Resistant starch occurs naturally in foods, but it can also be added as part of dried raw foods, or used as an additive in ...
