Scurvy is a disease that until the nineteenth century was common among sailors and others whose diets were deficient in vitamin
alina1380 [7]
<h2>Scurvy </h2>

Explanation:

(a) Collagen is the major structural component of cartilage,bones and tendons

  • The basic unit of collagen is tropocollagen and each tropocollagen consists of three coiled left handed polypeptide chains called α chains
  • Generally each α chain consists of a repeating tripeptide sequence called: G-X-Y
  • Here G represents glycine; X represents proline and Y represents hydroxyproline
  • Rigidity of collagen molecule is due to presence of proline and hydroxyproline
  • Hydroxylation of proline is catalysed by prolyl hydroxylase enzyme which use ascorbate,α ketoglutarate and oxygen
  • α ketoglutarate is oxidatively decarboxylated to form carbon dioxide and succinate
  • Sequence of events leading from a dietary vitamin C deficiency to symptoms such as bruising and breakdown of supporting tissues includes: tissue levels of ascorbic acid is low;  enzyme prolyl hydroxylase is inactive;  proline is not hydroxylated;  the triple helix is inadequately stabilized; collagen breaks down;  defects in tissues that depend on collagen ; tissues that depend on collagen are subject to breakdown and bruising

(b) Sailors are no longer susceptible to scurvy because fresh fruits which are the source of vitamin C source are available now

British sailors called "limeys" to this day,this term reflects the British navy's use of limes
