The term bisphosphoglycerate refers to specific enzymes. There are several different types of these enzymes that are unique to placental cells.
In biochemstry, it stand for 2,3-bisphosphoglycerate
1,3-bisphosphoglycerate . . . 3-phosphoglycerate
glyceraldehyde-3-phosphate . . . 1,3-bisphosphoglycerate
Glyceraldehyde-3-phosphate → 1,3-bisphosphoglycerate
Low BPG levels indicate a low hemoglobin level in the red blood cells.

A bisphosphoglycerate is any of a group of compounds containing two phosphoglycerate groups.
The intermediate products of glycolysis include glucose-6-phosphate, fructose-6-phosphate, fructose-1 6-bisphosphate, PGAL, bisphosphoglycerate, and PEP. The main intermediate products are fructose-1 6-bisphosphate, PGAL, and PEP.
Yes, Hemoglobin (Hb) is allosteric - it is also cooperative, which is a related but separate phenomenon. An allosteric protein has binding sites for effectors that can alter binding of another molecule or substrate. These effectors can be positive or negative. Hemoglobin has many negative effectors, which cause it to release the O2 that it is carrying. These include 2,3, Bisphosphoglycerate, Carbon Dioxide, and H+ (low pH).
The primary factor that determines how much oxygen is actually bound to hemoglobin is the partial pressure of oxygen (pO2) in the hemoglobin solution.
