Explain transmethylation reaction of amino acids.

Transamination, a chemical reaction that transfers an amino group to a ketoacid to form new amino acids. This pathway is responsible for the deamination of most amino acids. This is one of the major degradation pathways which convert essential amino acids to non-essential amino acids (amino acids that can be synthesized de novo by the organism).

the solar system used to have much dust particles option no d

geosphere and hydrosphere.
