Decarboxylation refers to the removal of the carboxyl group from a carboxylic acid and thus releasing carbon dioxide. Decarboxylases are enzymes that speed up the removal of the carboxyl group from acids. These reactants could be amino acids, alpha-keto acids, and beta-keto acids. Biotin is known to catalyze the decarboxylation of malonyl CoA to acetyl CoA during fatty acid synthesis.
Malonyl CoA is converted to acetyl CoA after decarboxylation assisted by biotin also known as Vitamin H. Alpha keto acids are involved in fatty acids synthesis and Malonyl CoA is an alpha-keto acid because the keto group is located in the first carbon near the carboxylic acid group. Keto acids have both a carboxyl group and a ketone group.
cl has mass number 35 and its atomic number is 17 so number of proton =atomic number 17 and number of neutron is =mass number -number of proton =35-17 =18
The products of chemical reactions often have completely different properties than the reactants, like viscosity, boiling and melting temperatures, etc.
That is because the atoms form new and different bonds to give the products.
