involved in chemical reactions. • Hydroxyl group: a chemical group consisting of an oxygen atom joined to a hydrogen atom. Molecules possessing this group are soluble in water and are called alcohols. • Carbonyl groups: a chemical group present in aldehydes and ketones and consisting of a carbon atom double-bonded to an oxygen atom. • Carboxyl group: a chemical group present in organic acids and consisting of a single carbon atom double-bonded to an oxygen atom and also bonded to a hydroxyl group.

Carbohydrates can be separated into three groups‚ monosaccharide‚ disaccharides and polysaccharides. Monosaccharide is the monomer of carbohydrates which contain hydroxyl group‚ such as glucose and fructose. Disaccharides are sugars that contain either aldehydes or ketone that react with hydroxyl group‚ such as maltose and lactose. Polysaccharides are the long chains of monosaccharide‚ which is called the polymer of carbohydrates. Monosaccharide and disaccharides can be tested by the Benedict’s test‚ as

Preparing nitriles from carbonyl compounds is useful in reactions because nitriles are versatile functional groups1. Not only are they versatile functional groups but they serve as precursors in several transformations. The cyano-group is found in many bioactive molecules and plays a role in hydrogen bonding to certain biological receptors.4 Nitriles are carboxylic acid derivatives because they can easily be converted to carboxylic acid under either basic or acidic conditions. Piperonal is an aromatic

Unit 1: Introduction to Biochemistry Lesson 1-4: Key Question How many electrons does Mg2+ have? (1 mark) Mg2+ has 10 electrons. A magnesium atom has 12 electrons with 2 of the 12 being valence electrons. Therefore the atom will lose the valence electrons which are located on the outermost shell to stabilize itself (outermost shell) as atoms tend to do what it easiest. Since magnesium lost 2 electrons it becomes positive as it is giving away electrons to stabilize other atoms. Hence magnesium

Case Study Summaries Case 1: J. Wellington Wimpy. Wimpy’s burger meal likely contained simple carbohydrates from the white flour bun‚ sugars in the ketchup‚ and saturated fats from the beef patty and cheese slice. Conversely‚ his turkey sub meal after the transformation likely provided complex carbohydrates from the whole wheat sub roll‚ lower amounts of saturated fats with high amounts of unsaturated fats in the turkey breast slices‚ and unsaturated fats from the veggies. Carbohydrates‚ which

Nicola Cooper Student No; cs329513 What effect does alcohol have on a person’s health and life expectancy? The consumption of alcoholic beverages dates back to approximately 10‚000 years ago when viticulture’ (the selective cultivation of grape vines for making wine) is said to have originated in the mountains between the Black and Caspian Seas. (1) It is one of the most commonly used psychoactive drugs in the world. Alcohol interacts with gamma amino bultyric acid (GABA) receptors in the

Figure 1: Schematic illustration of the principle of Biacore SPR to measure the interaction between analyte molecules in the flow with immobilized receptor binding sites on the surface. A) SPR uses an optical method to measure changes in the refractive index near the surface of a thin gold film on a glass slide. At a critical angle of incident light on the surface-solution interface an electromagnetic field or evanescent wave is generated. This is detected as absorption of light and a decrease in

Summary of Carbohydrates: Monosaccharides‚ Disaccharides‚ Polysaccharides Carbohydrates are molecules that are synthesized from carbon‚ oxygen‚ and hydrogen atoms. Some types of carbohydrates consist of a single unit consisting of a few atoms‚ while other carbohydrates consists of thousands of units linked together through chemical bonds. Glucose‚ maltose‚ and glycogen are three carbohydrates that are similar‚ but structurally different. Carbohydrates have the general molecular formula CH2O. Starch

1.) Explain why the following substances are added to soil by gardeners and farmers. a.) Lime CaO It increases the pH of soil.Soil that is too acidic presents two different problems for crops. First‚ the amount of necessary minerals in the soil such as potassium and calcium decreases. Second‚ aluminum and manganese levels increase to potentially toxic levels below a pH of roughly 5.5.Calcium oxide‚ addresses the problem. It reacts in water to release calcium ions and hydroxide ions‚ which raise
