Proline ball and stick model spinning. Proline (symbol Pro or P) [4] is an organic acid classed as a proteinogenic amino acid (used in the biosynthesis of proteins), although it does not contain the amino group-NH 2 but is rather a secondary amine.
A plastic ball-and-stick model of proline. In chemistry, the ball-and-stick model is a molecular model of a chemical substance which displays both the three-dimensional position of the atoms and the bonds between them. [1] The atoms are typically represented by spheres, connected by rods which represent the bonds.
A plastic ball-and-stick model of proline. These models usually comply with CPK coloring. These models usually comply with CPK coloring. In chemistry , the CPK coloring (for Corey – Pauling – Koltun ) is a popular color convention for distinguishing atoms of different chemical elements in molecular models .
Figure 6 shows models of anthrax toxin, left (at a scale of approximately 20 Å/cm or 1:5,000,000) and green fluorescent protein, right (5 cm high, at a scale of about 4 Å/cm or 1:25,000,000) from 3D Molecular Design. Models are made of plaster or starch, using a rapid prototyping process.

In enzymology, a proline racemase (EC 5.1.1.4) is an enzyme that catalyzes the chemical reaction. L-proline D-proline. Hence, this enzyme has two substrates, L- and D-proline, and two products, D- and L- proline. This enzyme belongs to the family of proline racemases acting on free amino acids.
Proline oxidase, or proline dehydrogenase, functions as the initiator of the proline cycle. Proline metabolism is especially important in nutrient stress because proline is readily available from the breakdown of extracellular matrix (ECM), and the degradation of proline through the proline cycle initiated by proline oxidase (PRODH), a mitochondrial inner membrane enzyme, can generate ATP.
Arginine and proline metabolism is one of the central pathways for the biosynthesis of the amino acids arginine and proline from glutamate. The pathways linking arginine, glutamate, and proline are bidirectional. Thus, the net utilization or production of these amino acids is highly dependent on cell type and developmental stage.
