Answer 1

Ans.Beta carotene is a red-orange pigment found in plants and fruits, especially carrots and colorful vegetables.

The name beta carotene comes from the Greek "beta" and Latin "carota" (carrot). It is the yellow/orange pigment that gives vegetables and fruits their rich colour.

Here are some key points about beta carotene-

• Beta carotene is a red/orange pigment found in many fresh fruits and vegetables
• Beta carotene is converted into vitamin A, an essential vitamin
• Vitamin A is toxic at high levels
• Beta carotene is a carotenoid and an antioxidant
• Foods rich in vitamin A include onions, carrots, peas, spinach and squash.
• GOLDENBREAD PROJECT- emphasizes
• the “build” phase of the design-build-test
  cycle. strain of baker’s
  yeast that has been modified with genes
  from another fungus to produce β-carotene,
  a nutrient we naturally obtain from eating
  foods such as carrots, sweet potatoes, and
  broccoli. In the body, β-carotene is converted
  to vitamin A, which is crucial for vision, the
  immune system, and other biological func‐
  tions.
• IMPORTANCE-In some developing countries that
  struggle with malnutrition, vitamin A defi‐
  ciency is a critical public-health issue.
• an engineered strain of baker’s yeast designed to generate β- carotene which could be used in bread to treat vitamin A deficiency.
