Carbohydrase is the name of a set of enzymes that catalyze five types of reactions, turning carbohydrates into simple sugars, from the large family of glycosidases. [ 1 ] Carbohydrases are produced in the pancreas , salivary glands and small intestine , breaking down polysaccharides .
In plants, carbonic anhydrase helps raise the concentration of CO 2 within the chloroplast in order to increase the carboxylation rate of the enzyme RuBisCO. This is the reaction that integrates CO 2 into organic carbon sugars during photosynthesis, and can use only the CO 2 form of carbon, not carbonic acid or bicarbonate. [citation needed]
These hydration and dehydration conversions of CO 2 and H 2 CO 3, which are normally very slow, are facilitated by carbonic anhydrase in both the blood and duodenum. [7] While in the blood, bicarbonate ion serves to neutralize acid introduced to the blood through other metabolic processes (e.g. lactic acid , ketone bodies ); likewise, any bases ...
Humans can consume a variety of carbohydrates, digestion breaks down complex carbohydrates into simple monomers (monosaccharides): glucose, fructose, mannose and galactose. After resorption in the gut , the monosaccharides are transported, through the portal vein , to the liver, where all non-glucose monosacharids (fructose, galactose) are ...
Pie charts of typical human body composition by percent of mass, and by percent of atomic composition (atomic percent) Body composition may be analyzed in various ways. This can be done in terms of the chemical elements present, or by molecular structure e.g., water , protein , fats (or lipids ), hydroxyapatite (in bones), carbohydrates (such ...
Lactose is a disaccharide found in animal milk. It consists of a molecule of D-galactose and a molecule of D-glucose bonded by beta-1-4 glycosidic linkage.. A carbohydrate (/ ˌ k ɑːr b oʊ ˈ h aɪ d r eɪ t /) is a biomolecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with a hydrogen–oxygen atom ratio of 2:1 (as in water) and thus with the empirical formula C m ...

[4] [5] Digestive enzymes are classified based on their target substrates : lipases split fatty acids into fats and oils ; [ 6 ] proteases and peptidases split proteins into small peptides and amino acids ; [ 7 ] amylases split carbohydrates such as starch and sugars into simple sugars such as glucose , [ 8 ] and nucleases split nucleic acids ...
