A cross-section of an ear of corn, showing the cob. A corncob, also called corn cob or cob of corn, is the hard core of an ear of maize, bearing the kernels, made up of the chaff, woody ring, and pith. Corncobs contain mainly cellulose, hemicellulose, and lignin. [1]
Some animals, particularly ruminants and termites, can digest cellulose with the help of symbiotic micro-organisms that live in their guts, such as Trichonympha. In human nutrition, cellulose is a non-digestible constituent of insoluble dietary fiber, acting as a hydrophilic bulking agent for feces and potentially aiding in defecation.
Being hindgut fermenters, these animals ferment cellulose in an enlarged cecum. In smaller hindgut fermenters of the order Lagomorpha (rabbits, hares, and pikas), and Caviomorph rodents ( Guinea pigs , capybaras , etc.), material from the cecum is formed into cecotropes , passed through the large intestine, expelled and subsequently reingested ...
Starches are insoluble in water. They can be digested by breaking the alpha-linkages (glycosidic bonds). Both humans and other animals have amylases so that they can digest starches. Potato, rice, wheat, and maize are major sources of starch in the human diet. The formations of starches are the ways that plants store glucose. [14]
Hindgut fermentation is a digestive process seen in monogastric herbivores (animals with a simple, single-chambered stomach). Cellulose is digested with the aid of symbiotic microbes including bacteria, archaea, and eukaryotes. [1] The microbial fermentation occurs in the digestive organs that follow the small intestine: the cecum and large ...
A record-setting heat blast that swept across the Midwest this week has been made worse by the region's vast fields of cornstalks. Through a natural process commonly called "corn sweat," water ...
They can differ greatly in terms of size and shape, which largely reflects the environment that they inhabit. [11] Siphonophores are most often pelagic organisms, yet level species are benthic. [11] Smaller, warm-water siphonophores typically live in the epipelagic zone and use their tentacles to capture zooplankton and copepods. [11]
