CHAPTER I INTRODUCTION In the present time‚ the rate of proliferation of diabetic people is continuously and rapidly increasing. Further studies show that the number of diabetes cases worldwide has doubled since 1980 and is now at startling 350 million diabetics. (Laino‚ 2011). Diabetes is a lifelong disease in which the level of glucose in the blood is abnormally high. Connected to this is a condition called hyperglycemia. Hyperglycemia is the technical term for high blood glucose (sugar).

are about half a million chloroplasts per square millimeter of leaf surface. The color of a leaf comes from chlorophyll‚ the green pigment in the chloroplasts. Chlorophyll plays an important role in the absorption of light energy during photosynthesis. Chloroplasts are found mainly in mesophyll cells forming the tissues in the interior of the leaf. O2 exits and CO2 enters the leaf through microscopic pores called stomata in the leaf. Veins deliver water from the roots and carry off sugar from

Abstract Pigments extracted from different greens have different polarities and may be different colors. Mixed pigments can be separated using chromatography paper. Chromatography paper is able to separate mixed pigments due to their polarity and solubility. Pigments of chlorophyll a‚ chlorophyll b and beta carotene will be separated on chromatography paper because each has its own polarity and solubility‚ which results in different distance traveled up the paper. Beta carotene is non-polar so it

Chromatography and a Spectrophotometer In this experiment‚ the separation of particular pigments‚ contained within a fresh spinach leaf‚ were examined. Paper chromatography is the process of separating certain molecules‚ or pigment molecules‚ based upon their polarity. Four different pigments were examined from the spinach leaf: chlorophyll a‚ chlorophyll b‚ xanthophyll‚ and carotene. Based upon looking at the pigments individual molecule structures‚ our group hypothesized that the most polar molecule
