The chemical reactions and pathways resulting in the formation of carnitine (hydroxy-trimethyl aminobutyric acid), a compound that participates in the transfer of acyl groups across the inner mitochondrial membrane. [GOC:jl, ISBN:0198506732]
Carnitine biosynthesis is a complex process that involves multiple steps and enzymes. It begins with the amino acid lysine, which is converted to trimethyllysine by a series of enzymatic reactions. Trimethyllysine is then hydroxylated to produce 6-N-trimethyllysine. This hydroxylated form undergoes a series of enzymatic transformations, including a decarboxylation reaction, to produce γ-butyrobetaine. The final step in carnitine biosynthesis is the oxidation of γ-butyrobetaine to carnitine by the enzyme γ-butyrobetaine dioxygenase. Carnitine is a vital nutrient for the body, playing a crucial role in the transport of long-chain fatty acids into mitochondria for energy production. It also plays a role in the regulation of blood sugar levels and the removal of waste products from the body.'
