    Abstract: Sugars containing either aldehyde (aldose), ketone (ketose) or hemiacetal groups can be oxidized and are classified as reducing sugars. As oxidation of carbohydrates is widely studied under the field of organic chemistry, the present work deals with the study of the redox reactions between peroxodisulphate and xylose underuncatalyzed and catalyzed ...

    Abstract: Levels of some trace metals (Fe, Zn, Cu, Mn, Cr, Ni, Pb and Cd) in Vernonia amygdalina (bitter leaf) obtained in Ibeno, Akwa Ibom State, Nigeria were quantified using standard procedures. Soil samples as well as roots and leaves samples of the plant were collected from three locations (Okoroitak, Inua Eyet Ikot, Iwuo Okpom) in Ibeno, where intensiv... Show More
