The most obvious, first effects (gingival and hair problems) of absence of ascorbic acid in humans come from the resulting defect in hydroxylation of proline residues of collagen, with reduced stability of the collagen molecule, causing scurvy. Increased serum and urine levels of hydroxyproline have also been demonstrated in Paget's disease. [10]

The amino acid composition of collagen is atypical for proteins, particularly with respect to its high hydroxyproline content. The most common motifs in the amino acid sequence of collagen are glycine-proline-X and glycine-X-hydroxyproline, where X is any amino acid other than glycine, proline or hydroxyproline. The average amino acid ...
HRG is a glycoprotein of 70-75kDa present at a relatively high concentration in the plasma of vertebrates.The primary structure of human HRG is predicted to be a 507 amino acid multidomain polypeptide consisting of two cystatin-like regions at the N-terminus, a histidine-rich region (HRR) flanked by proline-rich regions (PRR), and a C-terminal domain.

Prolidase deficiency generally becomes evident during infancy, but initial symptoms can first manifest anytime from birth to young adulthood. The condition results in a very diverse set symptoms, [3] the severity of which can vary significantly between patients, depending on the degree to which prolidase activity is hampered by the individual underlying mutation(s) in each case.

Work on one command at a time to avoid confusion. Trying to train two or three different things at once can leave your dog wondering which thing you're asking them to do.
A report on proposed changes to U.S. dietary guidelines suggests encouraging people to eat more beans and lentils for protein and less red meat. Updated guidelines are expected to go into effect ...
