Vi­ta­min from outer space

Down to Earth - - SCIENCE & TECHNOLOGY -

Vi­ta­min B3 could be of ex­trater­res­trial ori­gin. The vi­ta­min, which helps in the pro­duc­tion of nicoti­namide ade­nine din­u­cleotide (es­sen­tial for me­tab­o­lism), has been found to be present in sev­eral me­te­orites. This in­di­cates that the ori­gin of life might have been as­sisted by cru­cial mol­e­cules which came from space. A study an­a­lysed eight dif­fer­ent car­bon rich me­te­orites and found B3 present in all of them in pro­por­tions rang­ing from 30 parts per bil­lion to 600 parts per bil­lion.
