Dihydroxyacetone phosphate lies in the glycolysis metabolic pathway, and is one of the two products of breakdown of fructose 1,6-bisphosphate, along with glyceraldehyde 3-phosphate. It is rapidly and reversibly isomerised to glyceraldehyde 3-phosphate.ihydroxyacetone phosphate (DHAP, also glycerone phosphate in older texts) is a biochemical compound involved in many metabolic pathways, including the Calvin cycle in plants and glycolysis.
The human esophagus is about 10 inches (25 centimeters) long. The esophagus of fish is short, while that of giraffes is extremely long.. Digestion involves the breakdown of ingested food and the absorption of the resulting molecules into the body.
Esophagus. The esophagus is a hollow muscular tube that connects the back of the throat to the top of the stomach. In an adult, this tube normally ranges from about 10-14 inches in length, and one inch in diameter. At rest, the esophagus is closed but opens readily to accept food and liquids. The muscles in the upper portion of the esophagus are under voluntary control. The remaining portion consists of smooth muscle like the rest of the digestive tract and is not under voluntary control.
