ExtremeBDS [4]

Answer:

The sun, earth, and moon are held together by gravity, and they interact in lots of ways. The moon orbits the earth because of the pull of the earth. And the earth orbits the sun because of the pull of the sun. Because of the way they move relative to each other, we see phases and eclipses

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
