Nutritional science investigates the metabolic and physiological responses of the body to diet. With advances in the fields of molecular biology‚ biochemistry‚ nutritional immunology‚ molecular medicine and genetics‚ the study of nutrition is increasingly concerned with metabolism and metabolic pathways: the sequences of biochemical steps through which substances in living things change from one form to another. Carnivore and herbivore diets are contrasting‚ with basic nitrogen and carbon proportions

Antioxidants Antioxidants are natural compounds that are present in some foods‚ which help stabilize free radicals (a harmful unstable molecule produced naturally in the body as a bi-product of oxidation) and prevent them from damaging other cells. Importance of antioxidants Free radicals that are formed in the body are highly dangerous‚ as they are unstable molecules with an odd number of electrons. Since they have an odd number of electrons they seek and steal electrons from

six different runs of a reaction between thiosulfate and hydronium ion was used to plot a linear equation based on the Arrhenius equation. From the equation‚ the activation energy‚ Ea‚ of the reaction was obtained with an experimental value of 58.03 kJ/mol. The experiment showed that higher temperature leads to an increase in the rate of reaction‚ that a decrease in temperature would do the reverse‚ and that the concentration of reactants is directly proportional to the rate of reaction. The experiment

K (at zero K the substance has no entropy)‚ a substance will gain a certain amount of energy per mole and this will differ from substance to substance. Entropy values (S) are always positive and usually quite small so we measure them in J not kJ. Note: The units of entropy are J mol-1 K-1. Eg. Copper has an entropy (S) of 33.3 J mol-1 K-1 Questions 1. How much energy is

Marathon running‚ triathlons‚ games of football‚ basketball‚ etc‚ require energy that is released into the blood slowly (low GI). Examples of low GI foods are baked beans‚ pasta‚ oats and most fruits. Energy Balance and Cal/KJ – what are thy and how do they work? Cal and KJ are abbreviations for the terms Calories and Kilojoules; these terms are 2 different ways of measuring energy. It can be quite confusing though as often food is measured in kilojoules and exercise in Calories. This makes it

Denaturing of Proteins Research Paper Abstract: Introduction The experiments the objective is to determine‚ the possible measures of the denaturation process of several proteins by using a home based temperate The necessary applications of this experiment are to compile all the possible measures of the denaturation process in understandable units and explainable means. Other methods possible for research are by using a
