Amino acid Hydroxyproline. Chemical molecular formula Hydroxyproline

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.The secondary amine nitrogen is in the protonated form (NH 2 +) under biological conditions, while the carboxyl group is in the deprotonated −COO.. Proline was the second amino acid synthesized before its presence as a product of the hydrolysis of the protein molecule was established. Willstatter, investigating the position of the carboxyl group in N-methylproline, first obtained this amino acid in 1900..

L-proline is pyrrolidine in which the pro-S hydrogen at position 2 is substituted by a carboxylic acid group. L-Proline is the only one of the twenty DNA-encoded amino acids which has a secondary amino group alpha to the carboxyl group. It is an essential component of collagen and is important for proper functioning of joints and tendons.. Symbol: Pro P Molecular Weight: 115.13 Isolectric point (pH) 6.30 Molecular Formula: C 5 H 9 NO 2. Proline is one of the twenty amino acids that are used by living organisms as a building block of proteins (so called proteinogenic amino acids). Proline is one of the cyclic aliphatic amino acids that is a major component of the protein collagen, the connective tissue structure that binds and.
