Introduction and Purpose:
Carbohydrates are one of the main types of nutrients, and the main energy source of the human diet. It can be found in a wide range of both healthy and unhealthy foods such as bread, bean, cake, popcorn, cookies, and soft drink (Harvard.edu). The consumption of bad carbohydrate that increases your blood sugar should be limit. If the blood glucose stays high for too long, it can develop type two diabetes (womenheath.gov). In addition, carbohydrates are the most important source of metabolic energy for human body, plants, and in animals that eat plants (Bruice 2011). The human body uses energy produced by carbohydrate for your cells, tissues and organs. The extra carbohydrates also stored in liver and muscles for when it is needed. Carbohydrates come in a variety of forms. The most common and abundant forms are fibers, sugars, and starches (nlm.nil.gov). Glucose is a common known of sugar and it is one of the standards that were used in this lab. Glucose is a 6 carbon atoms, it is classified as an aldohexose (a hexose with an aldehyde group on one end). There are also other common standard that were used in this lab is fructose. Similar to Glucose, Fructose has 6 carbon atoms, however, it is a ketohexose (a hexose with ketone group on one end) (Bruice 2011).

They are monosaccharides, disaccharides, and polysaccharides. Monosaccharides are the simplest units of carbohydrates and a simple carbohydrate. They are the building block of more complex of carbohydrates such as disaccharides and polysaccharides. According to orthomolecular.org, monosaccharides are colorless; they can dissolve in water and have crystal like appearance (orthmolecular.org). Disaccharides are made up of two monosaccharide units linked through glycosidic bond. Polysaccharides are composed of long chains monosaccharides units linked by glycosidic

    In order to have energy our body transform carbs into sugar and when consumed in excess, they are processed into sugar in the blood stream, which is stored as fat if unused; besides the consumption of an elevate amount of carbs make you become overweight because it is super caloric, it also increases the chances of diabetes because of the irregularity of the blood sugar (Morgan, Rachel 2013.) Thus moderation is the key to have a balanced diet and a healthy…

    Vitamin B-6: This vitamin plays an important role in converting food to energy, along with helping the body to metabolize fats and proteins. It is also needed for proper brain development and function; makes hormones such as serotonin and norepinephrine (which affects mood) as well as helping the body make melatonin. In order to receive an adequate amount of vitamin B-6 I would consume nuts, beans, bananas, and potatoes to my diet because these tend to have large quantities of vitamin…

    Maltose is a sweet carbohydrate. Carbohydrates are a source of energy for the body for example glucose and a store of energy. Building blocks for polysaccharides for example cellulose in plants and glycogen in the human body and components of other molecules for example DNA, RNA, glycolipids, glycoproteins and ATP. Arabinose is an aldopentose – a monosaccharide containing five carbon atoms, and including an aldehyde (CHO) functional group. The structure…

    Summary Human Serum albumin (HSA) is a plasma protein in charge of the transportation of the fatty acids (Bhattacharya, Grune & Curry, 2000, p.721). HSA promotes the transportation capacity of plasma because it is currently at around 0.6Mm enabling it to carry more than six molecules of fatty acid. In addition, the HSA binds and agitates the pharmacokinetics of various drugs compounds. The HSA-fatty acid has two drug-binding sites, which are the sub-domains IIA and IIIA. The fatty acid IIIA coincides with the high affinity of the long-chain fatty acid binding site.…

    An example of a protein is transthyretin, an important transport protein. Another is an enzyme, whose function varies based on the shape that it is given. Enzymes allow all chemical bonds from the dehydration synthesis process to occur at a much faster rate than if there was no enzymes. Enzymes allow life to occur, without them, the reactions would take much too long for life to sustain. The final macromolecule is nucleic acids.…

    For example, glucose, a sugar, is a monosaccharide; these are carbohydrates in their simplest form (Timberlake, 2006). When only a few of these monosaccharide are linked together, they create oligosachharides. If many of the monosaccharides are bonded, they create polysaccharides. These are considered complex carbohydrates. A polysaccharide which is made up of amylose and amylopectin would be starch (Timberlake, 2006).…

    INTRODUCTION Fatty acid is a carboxylic acid with a long aliphatic chain, which is either saturated or unsaturated. Most of the naturally occurring fatty acids contain unbranched chain of an even number of carbon atoms, from 4 to 28. We usually derived fatty acids from triglycerides or phospholipids. Fatty acids are very important sources of fuel because, when they metabolized, they yield large amount of ATP .Fatty acids are regulated by certain transcription factors which control the action of genes which synthesize the fatty acids as well as cholesterol inside the body TYPE OF FATTY ACID I. ON THE BASIS OF NATURE OF COMPOUND I. TRIGLYCERIDES II.…
