Experiment no. 1: PHYTOCHEMICAL SCREENING INTRODUCTION Phytochemicals are define as the chemical compounds found or produced by the plants. The term is also define as the chemicals from the plant that may affect health [1]. This compounds are non-essential compounds which means that they are not required by the human body for sustaining life. There are more than thousand known phytochemicals. Some of the well-known phytochemicals are lycopene in tomatoes‚ isoflavones in soy and flavanoids in

then flasks 1 & 2 had 10 drops of Cl in them‚ 3 & 4 had 10 drops Br and 5 & 6 had 10 drops of I. Then in flask one 10 drops of sodium bromide were distributed into it. Next ten drops of sodium iodide were put into flask 2‚ followed by putting 10 drops of sodium chloride into flask 3 and 10 drops of sodium iodide into flask four. Afterwards 10 drops of sodium chloride and 10 drops of sodium bromide were put into flasks 5 & 6 respectively. A cork was placed on the top of each of these flasks so outside

GAS LAWS GROUP 1 Sheena Mae Agustin Hans Alcantara Renzo Bren Ado Miguel Afable Ron J Advincula De La Salle University - Dasmariñas Dasmariñas‚ Cavite Philippines ABSTRACT Gases behave in a similar way over a wide variety of conditions because to a good approximationthey all have molecules which are widely spaced‚ and nowadays the equation of state for an ideal gas isderived from kinetic theory. The combined gas law or general gas equation is formed by the combination of

a) Using a human cell of your choice‚ describe how organelles work together to make and secrete a protein (LO1. AC 1.1) An epithelial cell in the thyroid gland‚ called a thyrocyte forms spherical follicles that produce a protein called thyroglobulin. This is a globular protein that has a functional role in metabolism. The protein is used by the thyroid gland to produce thyroid hormones; thyroxine (T4) is an example of one of the hormones created. Thyroxine is formed by iodine binding to tyrosine

ABTS•+ were produced by the oxidation of a 7 mM ABTS solution with 2.45 mM potassium persulphate‚ and the mixture was allowed to stand in the dark at room temperature for 12–16 h before use. The resulting blue–green colored ABTS•+ solution was adjusted to an absorbance of 0.70 ± 0.02 at 734 nm. Briefly‚ 0.5 ml of the extract was added to 1

Ionic bonding is known as a type of chemical bond where the valence electrons are lost from one atom and gained by another. This exchange results in a more from one atom and gained by another. When an atom gains or loses electrons while being bonded with another atom an ion is formed. This bond causes an atom to become either a positive or negative ion. Electrons have a negative charge‚ meaning that if an atom loses an electron‚ the amount of protons are greater than electrons. This makes the atom
