long repeating chains of a basic unit or monosaccharide. All together‚ carbohydrates represent about 50% of green coffee’s base. Amino acids are present in green coffee at levels of about 10-13% of dry matter. Amino acids are molecules containing an amine‚ a carboxylic acid group (an organic acid that contains at least one carboxyl group of COOH) ‚ and a side chain (a chemical grouping that is attached to the main group and is specific to each compound). Lipids represent around 11-17% of coffee. They

Assignment #3: Production and Operations Management Marathon Oil – Case Study November 10.2010 BUS 508: The Business Enterprise Explain one possible option that Marathon could take to reduce the time involved in the production process. Oil refineries are huge sized plants‚ processing an average of a hundred thousand to several hundred thousand barrels of crude oil a day. Using process optimization‚ Marathon could reduce the time involved in the production process. The goal is to maximize

and propellers [1][2] and other things used on a daily basis. However‚ they are pollutants that cause serious damage to the ozone layer. Nevertheless‚ they are invaluable since they can also be used as intermediates to produce other functional groups (e.g.‚ amines‚ esters‚ and alkenes). Alkyl halides have the general formula RX (where R= alkyl/substituted alkyl group and X = F‚ Cl‚ Br‚ or I.) They are insoluble in water and sulfuric acid and are soluble in organic solvents.[3] They are synthesized for their

Milk is the probably the most nutritionally complete food found in nature. Whole milk contains vitamins (principally thiamine‚ riboflavin‚ panthothenic acid and vitamins A‚ B12 and D)‚ minerals (calcium‚ sodium‚ phosphorus‚ potassium‚ and trace minerals)‚ proteins (which include all the essential amino acids)‚ carbohydrates (mostly lactose)‚ and lipids (fats). Whole milk is an oil in water emulsion‚ containing approximately 4% fat dispersed as very small (micron sized) globules. The fat emulsion

Nucleophilic Substitution | Synthesis of n-Butyl Bromide and t-Pentyl Chloride | | Jessica | [Pick the date] | Abstract The synthesis of the alkyl halide n-Butyl Bromide from alcohol is the foundation for the experiment. During the isolation of the n-butyl bromide‚ the crude product is washed with sulfuric acid‚ water‚ and sodium bicarbonate to remove any remaining acid or n-butyl alcohol. The primary alkyl halide halide n-butyl bromide is prepared by allowing n-butyl alcohol to react with

Investigating the Activity of Cholinesterase and its Inhibitors Introduction: Enzymes are highly specific biological catalysts (proteins) that influence the rate of metabolic reactions (Smith‚ 1997). They are responsible for efficiently converting substrate molecules into products required to sustain life (Grisham et al.‚ 1999). The activity of enzymes can often be effected by other endogenous or foreign factors (e.g. inhibitors). Inhibitors are able to decrease the rate of enzymatic activity

Determination of Gatifloxacin and Ornidazole in Tablet Dosage Forms by High-Performance Thin-Layer Chromatography 43 A simple and sensitive high-performance thin-layer chromatography method has been developed for the quantitative estimation of gatifloxacin and ornidazole in its combined dosage forms. Gatifloxacin and ornidazole were chromatographed on silica Gel 60 F254 TLC plate using n-butanol: methanol: ammonia (6 M) (8:1:1.5 v/v) as the mobile phase and scanned at 302 nm using a Camag TLC Scanner

How neurological processes affect behaviour and impact the field of biological psychology Psychology as a field of study has evolved from the human need to understand ourselves and the causes behind our behaviours. Philosophy tried its hand first‚ attempting to describe it as a complex interaction between the mind and the body – between the mental and the physical. This basic idea resonates through this field of exploration through the years. While there have been diversions from this line of
