Glyceraldehyde 3-phosphate, also known as triose phosphate or 3-phosphoglyceraldehyde and abbreviated as G3P, GA3P, GADP, GAP, TP, GALP or PGAL, is a metabolite that occurs as an intermediate in several central pathways of all organisms. [2] [3] With the chemical formula H(O)CCH(OH)CH 2 OPO 3 2-, this anion is a monophosphate ester of ...
Triosephosphate isomerase is an enzyme that in humans is encoded by the TPI1 gene. This gene encodes an enzyme, consisting of two identical proteins, which catalyzes the isomerization of glyceraldehyde 3-phosphate (G3P) and dihydroxyacetone phosphate (DHAP) in glycolysis and gluconeogenesis .
The sequence around the active site residues is conserved in all known triose phosphate isomerases. The structure of triose phosphate isomerase contributes to its function. Besides the precisely placed glutamate and histidine residues to form the enediol, a ten- or eleven-amino acid chain of TPI acts as a loop to stabilize the intermediate.
Isomerases catalyze changes within one molecule. [1] They convert one isomer to another, meaning that the end product has the same molecular formula but a different physical structure. Isomers themselves exist in many varieties but can generally be classified as structural isomers or stereoisomers .
The translocator protein is responsible for exporting all the carbohydrate produced in photosynthesis by plants and therefore most of the carbon in food that one eats has been transported by the triose phosphate translocator. [1] Its three-dimensional structure was reported in 2017, revealing how it recognizes two different substrates to ...
Teeth whitening products can sometimes be a hit or miss, but there's a lot to love about the MySmile Teeth Whitening Pen, which pledges to get rid of stains from smoking, coffee, and wine.
Specifically, you lose 5/9 of 1% per month for each of the first 36 months and 5/12 or 1% for any month prior. This adds up to a: 6.7% annual benefits cut per year if you claim one to three years ...
A 27-year-old Ecuadorean immigrant cut a deal with prosecutors after raping a sleeping woman in Queens -- until the feds showed up and took him away.
