Chapter 7: Carbohydrates I. Carbohydrates A. Most abundant organic molecule in nature a) 3 major classes: Monosaccharides – simple sugar – polyhydroxy aldehyde or ketone; represent individual sugar Oligosaccharides – consist of short chains of monosaccharide units joined together by covalent bonds; 2-10 strings of sugar Polysaccharides – long chains having hundreds or thousands of monosaccharide units b) Functions: Provide energy thru oxidation – glucose oxidized for energy Supply carbon

percentage recovery of products. Test for purity and identification of products. Abstract Cyclohexene and cyclohexanol are both colourless aromatic compounds. The major difference between the two is the presence of the hydroxyl group present in cyclohexanol. This hydroxyl group can be removed by a process known as dehydration which results in the production of cyclohexene at the end of the dehydration process in the presence of a catalyst which‚ in this case‚ was 85% phosphoric acid.

The Disease Process of Atherosclerosis & its Complication; Myocardial infarction Loretta Zambito McMaster University HTH SCI 2C06 Dr. Ruth Hannon March 11‚ 2013 Atherosclerosis is the primary topic for this research paper. It is a disease process that can lead to many complications‚ one of which is called myocardial infarction; otherwise known as a heart attack. Atherosclerosis‚ or the hardening of the arteries‚ is defined as a disease characterized by abnormal thickening of the

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:

Thomas D Extended Research Task “The health benefits of red wine have come to light in recent years. Hope is on the horizon‚ and it may be in your glass!” Despite a seemingly indulgent high saturated fat diet‚ the French have a substantially lower death rate from coronary disease than any other major country. This phenomenon had been named the French Paradox and it is suggested that their consumption red wine may account for this strange occurrence (Mark Gould‚ 12/03/2006). In recent years

Organic chemistry Organic chemistry is one of the ‘branches’ of chemistry and is seen as distinct from other branches‚ such as inorganic and physical chemistry. It can be described as the chemistry living processes (often referred to as biochemistry) but extends beyond that. It focuses almost entirely on the chemistry of covalently bonded carbon molecules and as well as life processes‚ it includes the chemistry of other types of compounds‚ including plastics‚ petrochemicals‚ drugs and paint

other functional groups in the molecule‚ especially if they are close by‚ are more likely to profoundly modify the characteristics of the functional group in question. The functional group we are considering in this experiment is the hydroxy (or hydroxyl) functional group‚ -OH. This group shows up in a number of guises in organic compounds. Some of the common ones are shown in the table below. Functional Group Structure Compound Generic Name Comments alcohol In an alcohol‚ the -OH is

this lab was to prepare aspirin using its basic components: salicylic acid and acetic anhydride. Salicylic acid and acetic anhydride‚ along with an acid catalyst‚ react to form acetylsalicylic acid (aspirin) and acetic acid. In this reaction‚ the hydroxyl group on the benzene ring in salicylic acid reacts with acetic anhydride to form an ester functional group. The acetylsalicylic acid crystallizes as the solution cools and begins to come out of the solution. The acetylsalicylic acid is further purified

The phenolic compound is a type of organic chemistry which made of a hydroxyl group (-OH) and bonded to an aromatic hydrocarbon group known as phenols or phenolics (James‚ 2012). BHA and BHT are developed since 1947‚ which were used to check the oxidation in rubber products‚ before they were used as food preservatives. Nowadays
