Introduction
Carbohydrates are known as aldehyde or keto derivatives of polyhydric alcohols. They are polyhydroxy aldehydes or ketones or material that hydrolyze.2
Carbohydrates are categorized into2:
(a) Monosaccharide: formed of 1 sugar unit e.g. Glucose.
(b) Disaccharides: formed of two monosaccharides Such as Sucrose, Lactose, and Maltose.
(c) Oligosaccharides: yield 2–10 monosaccharide.
(d) Polysaccharides: yield more than 10 monosaccharides e.g. Starch.
Carbohydrates Derivatives
There are numerous derivatives of monosaccharides, several of which have pharmaceutical important.
1- Sugar alcohols (polyols):
Examples:
Sorbitol
It is a sugar alcohol with a sweet taste which the human body digests gradually. It can be gained by reduction of glucose, exchanging the aldehyde functional group to a hydroxyl group1.

Such as with other sugar alcohols, gastrointestinal pain might result when food products that have sorbitol are used up.1
• It is utilized in bacterial culture media to recognize the pathogenic Escherichia coli.1
• It is likewise utilized in the production of soft gels to stock single quantities of liquid
Glucose is liberated from dietary carbohydrate such as starch or sucrose by hydrolysis within the
There are four different types of hydrocarbons each having a different homologous series (formula for carbon chain). These being an alkane (formula = CnH2n+2), alkene (formula = CnH2n), alkyne (formula = CnH2n-2), and an alkanol which has the same formulae as an alkane only that is has a hydroxide molecule which replaces one of the hydrogen atoms (refer to figure 3 and
Carbohydrates are categorised in three many groups: Ø Monosaccharide – monomers and therefore contain single surgar. Ø Disaccharide – contain double sugars. Ø Polysaccharide – are large molecules containing many complex sugars. The general formula for carbohydrates is Cx(H20)y. Monosaccharides are white crystalline solids with low molecular mass and sweet tasting.
Jade Lim is young Asian student with little previous exposure to alcohol. After consuming one and a half Bacardi Breezer’s (1.5 standard drinks) she begins to feel nauseas and has a pulsating headache. It is important to understand the mechanism of action of ethanol in order to determine the potential effects on the patient. This report will investigate the underlying molecular mechanisms of ethanol.
Chemistry is at the heart of all nutrition. Thus, to truly grasp alcohol, one must know the basic molecular compounds that the body consumes and divides. The most accessible energy resource the body ingests is carbohydrates (rice, beans, breads, pasta, sugar, fruit, etc…). Carbohydrates are made
The primary method to control gestational diabetes mellitus (GDM) is through dietary regulation. The most effective method to control GDM via diet is through carbohydrate restriction and/or selectivity. It is recommended that pregnant women with GDM reduce their carbohydrate intake to 40% of the total caloric intake or can maintain a 60% carbohydrate intake but those carbohydrates must all come from low glycemic index foods. Examples of low glycemic foods are apples, spinach, black beans, split peas, oatmeal, and quinoa. Additional suggestions are to eat complex carbohydrates instead of simple, refined sugars. Eat small, frequent meals and snack often in between meals in order to maintain constant glucose levels throughout the day.
GHB, or Gamma-Hydroxy Butyric Acid is an intoxicating chemical with medical, recreational, and potentially entheogenic uses. It is a normal component of mammalian metabolism. It is naturally found in every cell in the human body and is most properly considered a nutrient. It is believed to be a neurotransmitter, although it is still unknown as to whether it exhibits all of the properties required to be considered one.
Roger E. Meyer writes this article to explain the effects of alcohol and how it affects the body. Once alcohol is taken into the body it is absorbed from the stomach and the small intestine and into the bloodstream. If too much alcohol is taken in the stomach may secrete a mucous that will slow absorption. One tenth of the alcohol exits form the body as sweat or urine, as the rest is slowly broken down by the body. This article and information can be helpful to me because it will give me a background and information on alcohol and what happens when one consumes it.
Is an important extract that contain the glucose were the body is in needed to form energy.
Alcohol chemically is any organic molecule with an OH functional group, however for the sake of this essay the term alcohol will refer to ethanol, the type of alcohol used in regular consumption. Ethanol is a by-product of yeast (a type of micro-organism). Yeast consume glucose, sugars, from fruits or crops such as barley they then excrete carbon dioxide (CO2) and ethanol (C2H5OH or C2H6O) (How is alcohol made?, n.d.). Yeast do this by the presence of the enzyme zymase in their digestive system. The enzyme speeds up the otherwise long process of glucose break down into carbon dioxide and ethanol, fermentation. This can be represented by the chemical formula:
Ketogenic diets, often called low-carbohydrate (low carb is slang), seem to be the latest diet trend. There are many different forms, all varying in different degrees. Ketogenic diets focus primarily on the limited intake of carbohydrates in the food pyramid. In order to clearly understand ketogenic diets, one must start with the basics-what are ketones and where are ketones found and produced???
Complexity of compounds is the reason they must be absorbed long before the physical activity. Starch a main area of complex carbohydrates. It has several bonds. Starches are tightly bound carbon molecules and have several attaching elements. This bonding complexity is the reason starches are capable of retaining large amounts of energy. These compounds should be taken into an athlete's body prior to intense physical activity because an energy storage supply is necessary when simple compounds are completely oxidized.
Ethanol, ethylic alcohol or simply alcohol is an organic substance with one or more hydroxil groups (-OH) [1]. For instance, it is used as a pharmaceutical compounds, in alcoholic beverages, as a dehydrating agent in labs and industries or as an antiseptic agent. Generally, ethanol is a CNS (central nervous system) depressant with anesthetic properties causing cognitive and motor damage at relatively low doses. Nevertheless ethanol in high doses can induce anesthetic effects, loss of sensory activity, nausea, vomiting, hypothermia and loss of consciousness. Some drugs have the potential to interact with alcohol and affect each others levels on blood, metabolism, absorption, distribution, excretion and change the colateral effects[2]. Additionally the duration of a regular consume and the amount ingested could change the effect of alcohol on drug metabolism [2].
Carbohydrates supply the body with the energy it needs to function. They are found almost exclusively in plant foods, such as fruits, vegetables, peas, and beans. Milk and milk products are the only foods derived from animals that contain a significant amount of carbohydrates.
The process of alcoholic fermentation begins with the use of enzymes. The enzymes begin to break down the long chains in starch molecules, a polysaccharide that consists of a large quantity of glucose molecules (C6H12O6) joined by glycosidic bonds as seen in figure 1, into single glucose molecules, a monosaccharide with six carbons and five hydroxyl groups. After the starch has become sugar, the enzymes are used once again, this time to convert the sugars into ethyl alcohol and carbon dioxide, CO2, as seen in figure 2 (World of Scientific Discovery, 2007). The carbon dioxide produced is released into the atmosphere, leaving water and ethanol, the alcohol, behind. Ethanol is a colorless flammable liquid with a molecular formula of C2H6O, giving it a molar mass of 46.07 grams per mole. Ethanol is also characterized by a melting point of -114°C or 159 K.
