"Hemicellulose" Natural Recordings by Native Speakers
Hemicellulose is a type of complex carbohydrate found in the cell walls of plants. It is a straight-chain polysaccharide made up of five-carbon sugars, such as arabinose, xylose, and glucose, that are linked together through beta-1,4 glycosidic bonds. Hemicellulose is broken down into smaller sugars by enzymes during the digestion process in the rumen of ruminant animals, such as cows and sheep, and is an important source of energy for these animals. It is also used in the production of biofuels, paper, and other products.
Hemiballism is a rare neurological disorder characterized by abnormal involuntary movements, specifically tremors and chorea (involuntary jerky movements), predominantly affecting one side of the body. The term "hemiballism" literally means "half-ballism", with "hemi-" referring to half and "ballism" referring to the sudden, jerky movements of the affected limbs.
Hemicolectomy is a surgical procedure where a doctor removes one half (hemi) of the colon (colectomy). It is typically performed to remove a tumor, diverticulum, or other abnormal growth that has formed in the upper or lower part of the colon.
