Phosphoanhydride
A compound that contains a phosphorus-oxygen bond and a bond between oxygen atoms, with one of the oxygen atoms present in the form of a phosphate group.
Phosphocreatine
Phosphocreatine, also known as PC or creatine phosphate, is a high-energy compound found in muscles. It plays a crucial role in energy metabolism during high-intensity, short-duration activities like weightlifting, sprinting, and other anaerobic exercises.Here's how it works:1. When you contract a muscle, phosphocreatine (PC) donates phosphate groups to Adenosine Triphosphate (ATP), which is the primary energy source for muscle contractions.2. The PC donates a phosphate group to convert ADP (Adenosine Diphosphate) back into ATP, effectively replenishing the energy stores in the muscle.3. This process is facilitated by the enzyme creatine kinase, which catalyzes the transfer of the phosphate group from PC to ADP.When you have high levels of phosphocreatine in your muscles, you can replenish ATP stores more efficiently, allowing for more intense exercise and better overall athletic performance. This is why creatine supplementation, which increases muscle PC levels, is a popular among athletes and fitness enthusiasts.

Phosphoglycolate
Phosphoglycolate is an intermediate compound in the Calvin cycle, a critical process in photosynthesis by which plants and some other organisms produce glucose from CO2 and water.Phosphoglycolate is formed by the breakdown of ribulose-1,5-bisphosphate (RuBP), a five-carbon sugar present in the Calvin cycle. When RuBP binds to CO2, it forms a 6-carbon intermediate, which then breaks down into two phosphoglycolate molecules (3-carbon-compounds) and an inorganic phosphate.Phosphoglycolate is then metabolized in a subsequent step called the phosphoglycolate pathway, also known as the C2 oxidation pathway. This pathway consists of two enzymes that convert phosphoglycolate into glycolate, which is then converted into glyoxylate and eventually into glycine. Glycine is then fed into the serine-threonine biosynthesis pathway and becomes the branch point for the production of various amino acids.Phosphoglycolate can also be detected as a product of certain plants damage, namely the RuBisCO poisoning, which is due to an overproduction of the enzyme Rubisco.
