Only statement d is incorrect, there are 6 families of amino acids in which they can be grouped on the basis of their metabolic precursors.
1. α -Ketoglutarate
Glutamate → Glutamine/Proline (also form Ornithine)/Arginine
2. 3-Phosphoglycerate
Serine → Glycine/Cysteine (also form Methionine SAM-sulfur donar in mammals)
3. Oxaloacetate
Aspaitate/Asparagine/Methionine/Threonine/Lysine
4. Pyruvate
Alanine/Valine/Leucine/Isoleucine
5. Phosphoenolypyruvate and erythrose 4-phosphate Tryptophan/Phenylalanine Tyrosine (from Phenylalanine by hydroxylation)
6. Ribose 5-phosphate
Histidine

Biosynthesis of Amino Acids
A. Amino acids are synthesized from glycolytic and citric acid cycle intermediates
Amino acids are the building blocks of proteins and are essential for various biological processes. They can be synthesized de novo in the body or obtained from dietary sources. One of the major pathways for amino acid biosynthesis involves the intermediates of the glycolytic and citric acid cycle.
B. Glutamate can be formed by amination of alpha-ketoglutarate
Glutamate, an important amino acid, can be synthesized by the amination of alpha-ketoglutarate. This reaction is catalyzed by the enzyme glutamate dehydrogenase, which adds an amino group to the alpha-ketoglutarate, resulting in the formation of glutamate.
C. Pyruvate on amination can form alanine
Alanine is a non-essential amino acid that can be synthesized in the body. Pyruvate, an intermediate of the glycolytic pathway, can be aminated to form alanine. This reaction is catalyzed by the enzyme alanine transaminase, which transfers an amino group from an amino acid to pyruvate, resulting in the formation of alanine.
Conclusion
In conclusion, option A, B, and C are correct statements about the biosynthesis of amino acids. Amino acids can be synthesized from glycolytic and citric acid cycle intermediates, such as pyruvate and alpha-ketoglutarate. Glutamate can be formed by amination of alpha-ketoglutarate, and pyruvate can be aminated to form alanine. These processes are important for the production of amino acids in the body and play a crucial role in various biological processes.
