lipid. Then using a square chromatoplate the lipid was subjected to a two-dimensional thin layer chromatography to separate the lipid into different components. Theoretically the egg yolk should contain TAGs‚ cholesterol ester‚ cholesterol‚ free fatty acids and polar lipids. In the end of the experiment the chromatoplate should show the polarity of the spots based on the adsorption of the spots in the mobile phase of the two-dimensional thin layer chromatography. Proper handling of the chromatoplate

GIVEN: TO DESIGN A 1000TPD CAPACITY H2SO4 ACID PLANT BASIS: 1 HOUR OF OPERATION. PURITY: PRODUCT WHICH IS TO BE MANUFACTURED IS ASSUMED TO HAVE STRENGTH OF 98% ACID. 1000TPD implies that we have Acid 1000 x 10 / 24 = 41666.67 Kg/Hr of 3 With 98% purity‚ the acid that is produced per hour = (98 x 41666.67) / 100 = 40833.34 Kg/Hr Kmoles of Sulfuric acid to be produced = 40833.34 / 98 = 416.667 Kmoles/Hr It’s assumed that overall absorption of the acid is 100 % = 416.667 / 1.0 Then‚ SO3 required

CARBOXYLIC ACID Introduction: Organic compounds containing (–C(O)–OH) as a functional group are called carboxylic acids. The –C (O)-OH group which itself is made up of a carbonyl group (>C=O) and a hydroxyl group (-OH) is called a carboxyl group (carb from carbonyl and oxyl from hydroxyl group). Carboxylic acid may be an aliphatic or an aromatic depending upon whether –C–OH is attached to an alkyl group ( or a hydrogen atom) or an aryl group. Their general formulas are; ALIPHATIC CARBOXYLIC ACID: R–C

These complementariness principles do not only underlie current ideas on the structure of the nucleic acids‚ but they form the foundation of all speculations‚ more or less well- founded‚ on their physical properties (denaturation‚ hypochromic- ity‚ etc.)‚ on the transfer of biological information from deoxy- ribonucleic acid to ribonucleic acid‚ and on the role of the latter in directing the synthesis of specific

Fatty acids (FAs) can ultimately be degraded through different pathways which include alpha‚ beta‚ and omega-oxidation. Alpha-oxidation occurs at carbon 2 of the chain‚ b-oxidation at C3‚ and omega-oxidation at methyl end of the fatty acid. The location of each mechanism also differs as alpha- oxidation occurs in peroxisomes only‚ beta-oxidation can take place in both peroxisomes and mitochondria. Omega-oxidation occurs in the endoplasmic reticulum of the various tissues. The importance of the differentiation

Jennifer Everett Phase 4 DB Instructor: Clement Yedjou 3/10/2015 Acid rain Acid rain is a result of air pollution that is harmful to the environment‚ generally caused by fuels being burnt. When any type of fuel is burnt‚ many different chemicals are produced. These gases that are released react with the water in clouds‚ and the rain from these clouds is acid rain. This type of acid disposition can appear in many other forms besides just rain‚ such as sleet‚ snow‚ and fog (Editorial Board‚ 2013)
