5-Deazariboflavin
CAS :5-Deazariboflavin is a proton carrier that is found in the mitochondrial cytochrome b. It has been shown to bind covalently to the protein, forming 5-deazariboflavin-protein adducts. These adducts are formed by reacting with amines and other amino acids present in the protein. In vitro studies have shown that 5-deazariboflavin inhibits Mycobacterium avium growth and acid production by binding to the enzyme pyruvate kinase, which is involved in glycolysis. 5-Deazariboflavin can also be used as an indicator of pH because it is reduced at low pH levels and oxidized at high pH levels. The second order rate constant for this reaction can be determined using kinetic data, such as absorbance or fluorescence properties.

CAS :Vitamin A palmitate is a fat-soluble vitamin that has antioxidant properties. It is available as a supplement in the form of retinol and retinyl palmitate. Vitamin A palmitate is an inactive form of vitamin A that can be converted to retinol in vivo by esterases and other enzymes. The conversion of vitamin A palmitate to retinol may be inhibited by various substances, such as estradiol benzoate. This conversion leads to the formation of free radicals, which cause oxidative injury to cells. Studies have shown that vitamin A palmitate can be toxic for humans because it interferes with the synthesis of mucin, an important constituent of human lungs and airways. Vitamin A palmitate also alters gene expression in some experimental models, leading to changes in cell growth or death.
