The affect of salt concentration on beetroot

Hundreds of studies have indicated that practicing this diet for several years can help fight a host of potential causes of inflammation, help maintain a healthy protein turnover rate — a process critical to slowing the aging process — and it even activates an incredibly powerful anti-aging gene. Now I know what you are thinking:

Best answer Alcohol Ethanol was shown to "fluidize" the membrane and dissolve the phospholipids. This is because it has both polar and non-polar ends. The affinity of ethanol for water and fat, based on its hydrogen bonding ability, altered the fluidity of the membrane. This changes the ability of membrane embedded proteins to function they are denatured due to altered hydrogen bonding and interact.

The higher the ethanol concentration the more pigment leakage. Temperature At high temperature molecules vibrate faster. The water will expand too, putting pressure on the membranes. Lipids become more fluid as temperature increases so the membranes become more fragile. Proteins, if heated too much, will denature due to their hydrogen bonding being disrupted because of the vibrations.

This will destroy membrane integrity and leave pores that will allow pigment leakage. The membrane becomes more permeable at higher temperatures. The proteins denature with high temperatures and the structures of the phospholipids are less stable.

At 43 degrees there is relatively little leakage due to the proteins being below their critical temperature. Freezing the beetroot causes ice crystals to rupture the cell membranes thus allowing the pigment to be extracted much more quickly. At lower temperatures lipid membranes become gels rather than staying in the fluid state.

Hence the solution at 7 degrees had less pigment leakage than at a higher temperature due to the decrease in particle movement. Proteins tend to stabilize pH hence their hydrogen bonding can be altered.

The lower the pH the more protein denatures. That means there are holes in the membranes, which allow pigment leakage. High pH also denatures membrane channel proteins and this is why some pigment leakage can be seen initially. After membrane proteins alter shape they can pass through by diffusion.

When in solution the alkaline pH changes their shape eventually and this makes them to reflect yellow wavelengths after a while hence the clear yellow solution that remained after 24 hours. The pigment is pH labile - it is denatured by pH — turning to a yellow chemical.

Betacyanins are alkaloid pigments, they are not pH indicators — their colour is stable over a wide range of pH. They are stable between pH 4 and 7, at high temperatures they are most stable in a pH between 4 and 5.

The basic pH of 9. Detergents Detergents are amphipathic molecules, meaning they contain both a non-polar "tail" and a polar "head". They are a class of molecules whose unique properties enable manipulation disruption or formation of hydrophobic-hydrophilic interactions among molecules in biological samples.

In biological research, detergents are used to lyse cells release soluble proteins and make membrane proteins and lipids more soluble. Like the components of biological membranes, detergents have hydrophobic-associating properties as a result of their non-polar tail groups.

Nevertheless, detergents are themselves water-soluble. Consequently, detergent molecules disperse and liquefy water-insoluble, hydrophobic compounds. They dissolve phospholipids and extract membrane proteins meaning that holes are left in the membrane that allow passage of pigments. The higher the detergent concentration the more membrane deterioration and the more pigment leakage.

Other stuff Thin slices have a larger surface area and so leak more pigment. Even though the slices were rinsed, pigment still leaks naturally because the cell membranes have been physically sliced open.

Therefore a level of colour leakage is expected and the pH 7 is a control for this. Membrane permeability should be judged based on the results of this solution.
