Recently, a study published has highlighted that high Vitamin-D levels reduce risks of COVID infection.

About Vitamin-D:

  • It is a fat-soluble vitamin naturally present in very few foods like fish liver oils, beef liver, cheese, and egg yolks.
  • It can also be produced endogenously
    (inside the body) when ultraviolet rays from sunlight strike the skin and trigger vitamin-D synthesis.

Role of Vitamin-D:

  • It helps maintain adequate calcium and phosphate concentrations in blood therebypreventing weakening of bones.
  • It also has other roles in the body like cell growth, neuromuscular and immune function, and reduction of inflammation.

Effects of Deficiency of Vitamin-D:

  • Rickets in children and Osteomalaciae., softening of bones in adults.
  • Bones can become thin, brittle, or mis-shapen.


Why in News?

According to International Energy Agency (IEA), transport biofuel production declined 8% globally in 2020 as the pandemic limited travel.

About Biofuels:

  • Any hydrocarbon fuel produced from an organic matter (living or once living) in a short period (days, weeks, or even months) is referred as a biofuel.
  • They may be solid, liquid or gaseous in nature:
    • Solid: Wood, dried plant material, manure, etc.
    • Liquid: Bioethanol, Biodiesel
    • Gaseous: Biogas.
  • Usage:
    • Can replace or be used in addition to diesel, petrol or other fossil fuels for transport, and other applications.
    • Can also be used to generate heat and electricity.
  • Reasons in favour of use:
    • the rising prices of oil,
    • High emission of the greenhouse gases from fossil fuels,
    • Augment farmer’s income, by obtaining fuel from agricultural crops.

Categories of Biofuels

  1. First generation biofuels:
  • Made from food sources like sugar, starch, vegetable oil, or animal fats using conventional technology.
  • Examples:Bioalcohols, Biodiesel, Bioethers, Biogas, etc.
  1. Second generation biofuels:
  • Produced from non-food crops or non-edible and crop wastes, e.g. stems, husks, wood chips, and fruit skins, etc.
  • Converted to bio-fuels by thermochemical reactions or biochemical conversion.
  • Examples: cellulose ethanol, biodiesel, etc.
  • These biofuels emit less greenhouse gases as compared to first generation biofuels.
  1. Third generation biofuels:
  • Produced from micro-organisms like algae.
  • Example: Butanol
  • Micro-organisms like algae can be grown on land and water unsuitable for normal food production.
  • However, fertilizers used in the production of such organisms lead to environment pollution.
  1. Fourth Generation Biofuels:
  • Genetically engineered crops which take in high amounts of carbon are used and harvested as biomass.
  • These crops are further converted into fuel using second generation techniques.

Some of such fuels are considered as carbon negative since their production pulls out carbon from environment.
