A triose is a monosaccharide containing three carbonatoms. There are only two trioses, an aldotriose (glyceraldehyde) and a ketotriose (dihydroxyacetone). Trioses are important in respiration. Monosaccharides are the simplest form of carbohydrates. ... For other uses, see Carbon (disambiguation). ... For other uses, see Atom (disambiguation). ... Fischer projection of D-glyceraldehyde Glyceraldehyde is a triose monosaccharide with chemical formula C3H6O3. ... Fischer projection of dihydroxyacetone Dihydroxyacetone (also know as DHA) is a triose carbohydrate with chemical formula C3H6O3. ... Cellular respiration describes the metabolism reactions and processes that take place in a cell to obtain biochemical energy from fuel molecules. ...
Triose-phosphate isomerase (TPI), is an enzyme (EC 5.3.1.1) that catalyzes the reversible interconversion of triose phosphates isomers dihydroxyacetone phosphate and D-glyceraldehyde 3-phosphate.
Triose phosphate isomerase is a massively efficient enzyme, performing the reaction billions of times faster than it would naturally in solution.
Triose phosphate isomerase is a dimer of identical subunits, each of which is made up of about 250 amino acid residues.
