The correct option is A Lysine and tryptophan
Biofortification is the process of breeding nutrient rich crops with higher levels of vitamins, minerals, fats, proteins, etc. with the idea to improve public health.
A protein rich, hybrid maize variety was developed in 2000, which had twice the amounts of the amino acids lysine and tryptophan compared to the existing maize hybrids. It had high amounts of vitamins A (retinol) and E (tocopherol) also.
The biofortified maize hybrids developed was not having enhanced levels of thiamine (vitamin B1), riboflavin (vitamin B2), fructose, lactose or vitamin B12.
Thiamine (vitamin B1) enables the body to use carbohydrates as a source of energy. It is essential for glucose metabolism and proper functioning of nerves and muscles.
Riboflavin (vitamin B2) is needed for growth and overall good health. It helps the body to break down carbohydrates, proteins and fats to produce energy.
Fructose is a simple sugar (monosaccharide) found naturally in fruits.
Lactose is a sugar (disaccharide) found in milk. Lactose is made up of glucose and galactose.
Vitamin B12 is synthesised by Escherichia coli bacteria in the human intestine. It is essential for the production of red blood cells and proper functioning of the nervous system.
