Fatty Acid Research Papers Samples For Students

Introduction

Beef is a significant source of proteins, and it is estimated that meat has 16.5 percent protein content (Chapter 9). Meat also has a considerable concentration of fats. Meat is an important source of proteins and fats, but it is unfortunate that excessive consumption of meat and meat products leads to the development of cardiovascular diseases owing to the presence of trans-fatty acids in those products. Dieticians worldwide are recommending that people should reduce the consumption of trans-fatty acids, but increase their intake of essential fatty acids. Essential fatty acids are more beneficial than trans-fatty acids (Chapter 8). Previous studies have ...

Introduction

The term lipids is used to refer to a group of organic compounds that are naturally occurring and that are all soluble in non-organic solvents such as benzene , chloroform, acetone and ether but not soluble in water. The later characteristic means that lipids can also be defined as amphiphilic or hydrophobic small modules. This amphophilic nature of lipids essentially allows them to be able to form structures such as liposome’s, vesicles or membranes when subjected to aqueous environments. The biological lipids mainly originate from two major build-blocks or biochemical sub-units: isoprene and ketoacyl groups. Another distinct characteristic of lipids ...

Abstract

The composition of the foods people consume has a significant influence on their health. Whole certain components in certain foods offer protection against the development of certain disease conditions, the consumption of other components at certain levels might predispose one to certain diseases and disease conditions. The processing industries have a role to inform the consumer of the ingredients in their food products. This is necessary for the consumer to make informed decisions about their dietary choices. This requirement is enforced by the role through regulations passed by government agencies. Even then, certain compounds that are present in processed ...

Introduction

Biomass is a biological material obtained from a living organism or a recently living organism. The word biomass is derived from two Greek words; bio meaning life, and maza meaning mass (Demirbas, “Fuels from Biomass” 43). Biomass means non-fossil and bio-decomposable organic matter (originating from plants, animals and microorganisms). The products, byproducts, residues and waste from agricultural processing, all constitute biomass. Bio-waste simply means non-fossil and biodegradable waste that is composed of organic matter. Bio-wastes include food and kitchen wastes, garden and park wastes, and wastes from food processing plants. Bio-waste is therefore an element of biomass.
Non-fossil wastes that are ...

Introduction

Waste biomass is usually in the form of manure, agricultural residues, municipal sewage sludge, municipal solid waste, and industrial bio-sludge which can be converted to animal feeds, alcohol fuels or industrial chemicals. There are various processes which are employed to convert this waste into the respective useful end products rather than being dumped away. The complexity of these processes depends on the kind of technologies being used. Conversions of waste biomass into renewable energy forms play a major role in reducing the dependence on crude oil and thus promote economic growth. The process of waste biomass conversion to useful products ...

Gas Chromatography-Mass Spectrometry Analysis (GC-MS) is a technique that incorporates chromatographic and spectroscopic techniques in separating and identifying constituents in a sample. According to Erika, Josefina and Maria (2011), the major goal of the technique is in quantifying an amount of a sample, which is done by comparing the relative concentrations among the atomic masses in the produced spectrum. The sample that needs to be quantified is organic and volatile, or semi volatile.
The GC part is used to separate is essential in carrying out separation techniques where mixtures are isolated from their constituents using a temperature-controlled capillary column. Smaller molecules in ...

Executive Summary

The results of the recent studies among U.S. pregnant women prove that fish consumption during pregnancy benefits the cognition of the offspring in infancy but at the same time, high levels of mercury that fish contain have adverse effects on the cognition of little children. So, it is recommended to pregnant women to look for the fish species with a low level of mercury.
The issue whether pregnant women harm their babies or on the contrary benefit the child’s brain development while consuming fish is ambiguous. There has been a great quantity of researchers who have been studying ...

Harvey requires enough energy to perform. Consequently, he must consume enough calories to meet all his energy needs. The actual requirement for calorie intake depends on one’s level of fitness and bodyweight. In addition, the intensity, frequency, and duration of physical activity also greatly influence one’s actual energy requirement.

Carbohydrates

Given that Harvey’s daily workouts involve high-intensity activities, his calorie intake should comprise of between55 to 70 percent carbohydrates. In this case, 3 grams per pound of body weight would be appropriate. Based on this recommendation, Harvey should consume approximately 480 grams of carbohydrates per day in ...

Abstract

Adequate nutrition is required for optimal wound healing. The normal processes that allow the progress of wound healing are disrupted due to nutritional deficiencies. Increased infection rates and decreased wound tensile strength are associated with malnutrition. Chronic on-healing wounds are formed in malnourished patients or individuals. Such patients can develop infections, pressure ulcers, and delayed wound healing. Morbidity and mortality among malnourished patients with chronic wounds constitute a serious clinical concern. Wound healing is considered as a complex process. It is the process of replacing injured tissue with new tissue (produced by the body). Production of new tissue is associated with ...

Introduction

In previous decades, epidemics were associated entirely with communicable diseases. However, a recent global phenomenon is the significant rise in incidence of chronic diseases linked to individual lifestyles. Unhealthy diet, inadequate physical activity, smoking, and alcohol intake all play a role in initiating the physiologic changes that lead to the development and progression of lifestyle-related conditions including cardiovascular disease, type 2 diabetes, and cancer (Strychar, Elisha & Schmitz, 2012). These are the top causes of death in populations as reported by many countries.
Because of the association with lifestyle factors, such illnesses are largely preventable but require complex management once acquired. ...

The World Health Organization defines genetically modified foods (GMO) as “organisms in which the genetic material (DNA) has been altered in a way that does not occur naturally”. It involves technology often referred to as gene technology, modern biotechnology or genetic engineering. The process allows for selective transfer of genes from one organism to another. The transfer of genes can be done between organisms of the same species or of different species. Genetic engineering has been practiced for many years. We often hear of cases where a specific gene is selected from an animal or plant and introduced into a different organism ...

Abstract

This Paper illustrates the physiological effects of puberty during adolescence. It gives definitions of puberty and adolescents and tries to correlate the two in checking for the effects on each other. The paper gives the psychological changes brought about by the outward changes of an individual during the growth stage of adolescent. Every person has experienced this occasion of ambiguity known as puberty. It conveys instances of perplexity as adolescents are often trying to comprehend who they are and try to discover an identity. Santos (2007) describes puberty as “a period of quick bodily maturation involving hormonal and physical transformations ...
