Study GuideBiochemistry-II–Amino Acid Metabolism:Carbon1.1-Carbon MetabolismIn our cells, many important reactions involve moving tiny chemical pieces called1-carbon units(like–CH₃,–CH₂–, or–CHO). These reactions are called1-carbon metabolism.To make them work, the body mainly depends on two helpers (cofactors):•Folic acid (folate)•Vitamin B₁₂Together, they help build DNA, RNA, amino acids, membrane lipids, and neurotransmitters. In otherwords, they support growth, repair, and normal cell function.Folic Acid: The Carrier of One-Carbon UnitsWhy folic acid is importantFolic acid helps the cellactivate, carry, and transfer single-carbon groups. These reactions areessential for:•Amino acid metabolism•DNA and RNA synthesis•Making membrane lipids•Producing neurotransmittersSome medicines even target folic acid metabolism to stop cancer cells or bacteria from growing.Structure of folic acidFolic acid is made ofthree parts:1.Pteridine ring (6-methylpterin)2.p-Aminobenzoic acid (PABA)3.Glutamic acidPreview Mode
