Give an overview of Amino acid biosynthesis.

Amino acid biosynthesis is a fundamental process in metabolism, enabling organisms to produce essential and non-essential amino acids required for protein synthesis and various biochemical functions. The biosynthesis of amino acids involves several interconnected metabolic pathways, utilizing intermediates from glycolysis, the pentose phosphate pathway, and the citric acid cycle. The synthesis process is tightly regulated to maintain homeostasis and ensure the availability of amino acids in response to cellular demands.

Precursor Metabolites and Biosynthetic Pathways

Amino acids are synthesized from key metabolic intermediates derived from central metabolic pathways. These intermediates serve as the backbone for amino acid formation:

1. 3-Phosphoglycerate (Glycolysis) – Serves as a precursor for serine, glycine, and cysteine.
2. Pyruvate (Glycolysis) – Leads to the synthesis of alanine, valine, _________ __________ _________ ____ ___ __________ _____ ____ _________.
