It is often shortened to MCT oil. The individual members of this class of fatty acids were named for the length of their carbon chain. They have between six and twelve carbons. Fatty acids with more than twelve carbons are classified as long chain triglycerides (LCT). Fatty acids with fewer than six carbons are called short chain triglycerides (SCT). Coconut oil and palm oil are both naturally high in medium chain triglycerides. Sometimes people get confused about

RESEARCH PAPER ON BIOLOGICAL ACTIVITY OF ACTINOMYCETES ................ ABSTRACT: The microorganisms are ubiquitous in nature. They are found in probably every environmental condition present on earth. Actinomycetes were originally considered to be an intermediate group between bacteria and fungi but now are recognized as prokaryotic organisms with high G+C (>55%) content in their DNA. Our project aim is to evaluate some biological activities of Actinomycetes like:

Hydrocarbons Jessa Grace B. Castillo* and Stephanie Chua Department of Chemistry‚ University of Santo Tomas‚ Manila‚ Philippines ______________________________________________ Hydrocarbons are organic compounds containing only hydrogen and carbons and further divided in major types. Hydrocarbons react differently in reagents. The basis of determining an unknown hydrocarbon is due to the differences in reactions of hydrocarbons. An unknown compound is determined using tests. The unknown gives

alkenes‚ alkynes‚ and aromatic hydrocarbons. Because of their relatively non-polarity‚ all hydrocarbons are insoluble in water. When hydrocarbons burn in sufficient oxygen‚ carbon dioxide and water are the sole products. The main structural difference among hydrocarbon families is the presence of double or triple bonds between carbon atoms. The alkanes are saturated organic compounds‚ or those with only single bonds. Unsaturated organic compounds are those which have double or triple bonds. [1] Many

Identification of the side-chains. Side chains are the carbon chains that are not in the parent chain‚ but are branched off from it. 4. Identification of the remaining functional groups‚ if any‚ and naming them by the their ion names (such as hydroxy for -OH‚ oxy for =O‚ oxyalkane for O-R‚ etc.).

BOILING POINTS AND MELTING POINTS PART 2 Name: Grethel Zegarra Date of Lab: October 26‚ 2010 Date lab is due: November 2‚ 2010 HYPOTHESIS The boiling point in degrees Celsius will increase as the number of carbon atoms increase. The melting point of the unknown will indicate its mixed substances. The boiling point will increase as a result of the different branching of the OH‚ the melting point will be affected by the different positioning of the OH on the benzene ring. PURPOSE To introduce

Cars diving around create food for plants to turn the carbon waste in to air‚ but there is also the fact of the car that leaks oil or gas on the ground and making a chemical waste pollution. This waste can be very damaging to an ecosystem to the point that it can kill the wildlife‚ plant life‚ and even hurt
