Online Inquiry

Organic acids are acidic organic compounds (excluding amino acids) containing carboxyl groups that are widely found in living organisms. In animals and plants except a few organic acids exist in the free state, generally in the form of salt or ester combined with potassium, sodium, calcium plasma.

Many organic acids play an important role by directly participating in biochemical reactions in the process of life activities. For example: 1) antibacterial, antiviral and anticancer effects; 2) softening blood vessels and promoting the absorption of calcium and iron; 3) acting as intermediate products of metabolism; 4) helping gastric juice to digest fats and proteins; 5) Preventing diseases and promoting metabolic effects, etc. In food research, the accumulation of organic acids is an important indicator of the flavor quality of fruits.

Creative Proteomics has established a quantitative analysis method for organic acids based on LC-MS/MS platform, which simultaneously detects 60+ organic acids which can be applied to practical sample detection in metabolomics and foodomics.
