  1. 1, 2 and 3 are correct but 4 is wrong.

  2. 1 and 3 are correct but 2 and 4 are wrong.

It's deficiency also leads to mental retardation, increased abortions, still births and infant deaths. Vitamin B$ _{6}$ is otherwise known as pyridoxine. It is a component of coenzyme pyridoxal phosphate. Fructose is a hexose monosaccharide ketose sugar abundant in fruits. Globulins are a family of globular proteins.
