Lactose College Essays Samples For Students

Lactose intolerance is an inability to digest milk sugar (lactose). After eating or drinking milk or dairy products people with this disorder may get uncomfortable side effects - such as diarrhea, stomach pains, bloating, nausea, and gas. The symptoms usually occur about 30 minutes to two hours after ingesting dairy products. Digestive problems appear because some people do not have enough the enzyme lactase. The lactose intolerance is more common among people of Asian, African, and South American descent than in Caucasians. Lactose intolerance is largely inherited due to genetic factors. The other causes of this condition include gastroenteritis, ...

Industrial microbiology has helped greatly in the discovery and development of substances that we use in our day to day life. It applies scientific and bioengineering techniques to processes and materials. Microorganisms produce valuable products of industrial microbiology.(Law 15) They include; Antibiotics, fermentation beverages, enzymes for amino acids synthesis, dairy products, and recovery of minerals from low grade ores, waste and waste water management, Biodegradation of xenobiotics, synthesis of chemotherapy drugs, just to name but a few. It’s a field that requires people to research on existing problems find or discover new products, get ways of producing and commercializing ...

Introduction

TLC or Thin-layer chromatography refers to a technique that is applied in the separation of mixtures that are not volatile (Reich & Schibli, 2007). The process is done on a sheet of plastic, glass, or aluminum foil that has been coated using a thin layer of material that is adsorbent such as aluminum oxide, silica gel and cellulose (Sherma & Fried, 2003; University of Colorado, 2014). This adsorbent layer is referred to as the stationary phase. The sample is usually applied using a capillary tube on the plate, and the sample is taken up the plate through capillary ...

The cow became one of the idols in Africa. Africans generally learned to appreciate and adore the cow. The Dinka, in a show of their love for the cow, have designed four hundred different names used to refer to the cow. The Maasai of Kenya are exceptions to idolizing the cow and their love for the cow. This has led them to believing that the cow was given to them by the gods, and on that basis they are true and dear to the cow. It is considered to them a blessing to herd and keep more herds of cattle as ...

- What is the basic structure of DNA?
The DNA’s basic structure is of a 3D double helix, which is consisted of two chains; each one of these chains is constituted by subunits that are called the nucleotides. Having four different kinds of nucleotides present on those chains in a given sequence, these are defined as polynucleotide chains. The polynucleotide chains, on their turn, are known as DNA chains or strands and the nucleotides of each chain are interlinked by hydrogen bonds, keeping the two together.
- A gene has three triplets: AAT, ATA and TAC. What are ...

Microbiology Lab

Abstract
This laboratory report tries to recognize an unknown bacterial species. The Gram stain disclosed bacteria to be both gram-negative and positive and via microscopy it confirmed to be rod and cocci respectively. Now two different bacteria were on the agar. One was a coliform and other a non coliform. The bacteria were exposed to all essential microbiological techniques employed to recognize an unknown bacterial species. The unknown comprised about 1% of the total bacterial flora of humans and even most of the warm-blooded animals. The bacteria are the most extensively studied prokaryotic organism, and an essential species in the ...

The model of complete replacement by Christopher Stringer and Peter Andrew states that 200,000- 150,000 years ago the archaic humans evolved to the modern humans in Africa and then later migrated to other parts of the world replacing the Neanderthals around 60,000 -40,000 years ago. This theory suggests that all people have an African ancestry (Kuklik & Henrika, 28).It also argues that all other forms of Humans like Homo erectus have gone extinct. It suggests that the developments seen in humans today are recent.
Regional continuity model also known as multiregional evolution model by ...

It is widely accepted that a sufficient food and water consumption is an integral part of living and health promotion. Food safety and quality are therefore considered to be a major concern for food manufacturers, policy makers and general public. Although there is a significant progress in advisory labelling practice, undeclared allergens can sometimes be added into food as a result of a manufacturing process. Allergens can be defined as a substance capable of triggering immediate hypersensitivity (AAAAI, 2014). Food Standards Agency (FSA) (2014) has calculated that each year approximately 10 people die from food-induced anaphylaxis. Poorly controlled production of food also damages socioeconomic status ...

The purpose of nutrition labelling regulations is to inform the consumer of the nutritional properties of a food item and includes two components: nutritional declaration and supplementary information. The Federal and Drug Administration (FDA) is responsible to ensure that foods sold in the United states, whether produced domestically or from foreign countries are safe, consumable and appropriately labelled. Although regulations are standardized and established, these may change over time. It is the responsibility of for the food industry to stay abreast with the legal food labelling regulations. All regulations are published in Federal register and complied annually in 21 Code ...

1. What happens to glucose or galactose when the Cu2 in Benedict’s is reduced?
The glucose and galactose both monosaccharaides are oxidized. The cyclic structures of both sugars are opened resorting to an aldehyde group at the end of the aliphatic compound. The aldehyde group is the one that reduces benedict’s solution and oxidizes the sugars.
2. Would you expect fructose or glucose to form a red color rapidly with Seliwanoff’s reagent?
Fructose is a ketose therefore, a deep red color will form quickly with Seliwanoff reagent, while glucose an aldose with form a light pink color ...

Describe the difference between an obligate and a facultative aerobe.
Obligate and facultative aerobes are the same in terms of their ability to use oxygen in their respiration process. However, obligate aerobes requires oxygen to oxidize substrates such as sugar and fat to produce ATP (energy). Obligate aerobes are more efficient in converting substrates to ATP. The key process in aerobic respiration is the conversion of sugar to ATP shown in reaction 1 below:

In the reaction 36 molecules of ATP is produced per molecule of glucose. It is actually a slow process which comprises 3 ...

Pathogenic and Non-pathogenic Organisms

Similarities in both organisms include the fact that both organisms are non-sporulating. Although, not the only metabolite, Salmonella enterica can produce lactate as one of its metabolite while Lactococcus lactis produces lactate. Both organisms are anaerobes, feeding by fermenting substrates (PHAC, 2010). Salmonella enterica ferments glucose while Lactococcus lactis ferments milk.
Salmonella enterica is different from Lactococcus enterica in several ways. From gram staining, Salmonella enterica is a gram-positive organism while Lactococcus lactis is a gram-negative organism. At the level of feeding, Salmonella enterica feeds on a wide range of carbohydrates (PHAC, 2010). It is a heterofermentative organism whereas Lactococcus lactis is a ...

Background information on Giardia

Giardia is luminal intestinal flagellated protozoan parasite. Giardia lamblia( also known as G. intestinalis or G. duodenalis) is the most common species that usually exhibits a typical fecal-oral lifecycle. Giardia lamblia) colonizes the upper portions of the small intestine and is the most common protozoan isolated from human stools. The prevalence is estimated at 200 million clinical cases per year [ CITATION Annd3 \l 1033 ].
Giardia lamblia exists in two forms, an active form called a trophozoite, and an inactive form called a cyst. The active trophozoite attaches to the lining of the small intestine with a "sucker" and is responsible for causing ...
