Pure Garcinia Cambogia is a pumpkin shape fruit which exclusively is indigenous to South Asia. The rind of the fruit contains Hydroxycitric Acid (HCA), which helps in controlling weight. Knowing the importance of HCA, we use highest 95 HCA with 1400mg tablets serving not just 50, 60 and 85. With higher amount of HCA these tablets can be better for weight management than tablets having low value of HCA. br br HCA stands for Hydro Citric Acid. Its IUPAC name is 1,2-dihydroxypropane-1,2,3-tricarboxylic acid and its chemical formula is C6H8O8. HCA posses a molar mass of 208.12 g.mol−1. br br As of now, you know what is HCA, but you should also know that what is a citric acid? A citric acid is found in the human body during the process of metabolism and if we talk about the rich sources of an HCA in nature then it can be found in various fruits and vegetables such as Tomatoes, Oranges, Lemon, Tamarind, Garcinia Cambogia and Hibiscus sub da Riffa etc. Moving ahead towards its chemical composition then HCA has four isomers (+)- and (-)- in both hydroxy citric acid and also hydroxy citric acid. If we talk about the (-)-hydroxy citric acid isomers which have rich source of Garcinia cambogia is a very good competitive inhibitor of ATP citrate lyase, which is an enzyme presents in animals (including human beings) used to represent one of the important steps of their fatty acid biosynthesis as it converts citrate to acetyl CoA.
