Abstract Vitamin C‚ also known as ascorbic acid‚ is a water soluble vitamin that is regarded as one of the safest and most effective nutrients. Vitamin C can be found in most fruits and vegetables. The goal of the experiment is to find out the concentration of vitamin C in three citrus fruits‚ orange‚ lemon and lime‚ and to compare them and find out which fruit contains the highest concentration of Vitamin C. By using the juice from each fruit to make a solution to combine with 10cm³ of DCPIP until

Measuring the Vitamin C content in a variety of fruit juices Background Information Vitamin C‚ also called ascorbic acid‚ is a water soluble vitamin. It is a powerful reducing agent that is able to decolourise blue DCPIP (2.6-dichlorophenol indophenols). The decolourisation of DCPIP can therefore be used to calculate the vitamin C content of a variety of fruit juices. Research Question – To determine how the content of Vitamin C (%) will differ in fresh fruits (orange‚ mango‚ lemon‚ lime‚ blackcurrant

Intracellular free calcium levels: Intracellular free calcium levels were estimated according to the method of Luo and Shi (Luo and Shi‚ 2005). Briefly‚ hippocampi were isolated from mice brains and subjected to hippocampal cells isolation as described later. The cells obtained were incubated with Fura-2 AM at 37°C with gentle shaking. The fura-2 loaded suspension was centrifuged for 10 minutes‚ pellet was washed once with Ca2+-free buffer and was centrifuged again. Aliquots of the washed suspension
