Biochemical Overview of Daily Food Intake

Lindy H. Borres Kurt Melon C. Calonia Hazel Mae D. Reyes ACTIVITY #1 November 26, 2013 TTh Biochemical Overview of Daily Food Intake INTRODUCTION The study of biochemistry has made a significant contribution on other branches of sciences which made it play a major role in understanding people’s lives. Biochemistry is actually a dynamic science which contributes important information to biology, medicine, nutrition, agriculture, physiology, genetics and immunology; practically all of the primary specialties in the life science.

Biochemistry, in broad terms, is the study of the chemical composition of the living matter and the biochemical processes that underlie life activities during growth and maintenance (Singh et al. , 2004). Biochemistry emerged as a separate discipline when scientists combined biology with organic, inorganic, or physical chemistry and began to study such topics as how living things obtain energy from food, the chemical basis of heredity, and what fundamental changes occur in diseases (Nazimabad, 2012).

Much of biochemistry deals with the structures, functions and interactions of iological macromolecules, such as proteins, nucleic acids, carbohydrates, and lipids, which provide structure of cells and perform many of the functions associated with life. Different macromolecules such as food can assemble in larger complexes, often needed for biological activities. Food, for instance, is a good source of one or more protein, carbohydrate, or lipid, depending exactly on the composition of the kind and the amount of intake. Living organisms need food for energy, growth, repair, defence, and reproduction.

To validate the above concepts, an experiment was conducted with the following bjectives: 1) to determine the average amount of daily food intake of a person; 2) to observe the relative effects of the interaction of biological molecules in the body; and 3) to evaluate the importance of food in the body. DISCUSSION vital to generate matter and energy, which through their changes are utilized enough for us to process information. This kind of harmonization is dependent on the kinds of biomolecules that we have as they are the building blocks of what we aim to create as messages.

What’s more, these biomolecules can certainly rely on what kind of ubstance we intake that will greatly affect us as a solitary and logical system. Food, for instance, is a good example of a substance that majorly affects a system, not only in terms of a particular aspect, but as in every single one. Food is an essential exogenous substance normally eaten or drunk by living organisms. As a living system directly dependent on the exogenous substances, food is crucially needed for everyday living, alongside with water and oxygen.

The food that we eat is our main source of energy given a specified amount of time. Food ontains essential nutrients, carbohydrates, fats, proteins, vitamins, and minerals that are needed by our body for proper exhibition of daily biochemical and metabolic processes. The quantity and quality of the food we intake provides our body the sustenance and proper physiological functions for diverse types of daily activities. If we eat, our body processes and absorbs the nutrients present in the food.

These nutrients, in turn, are ingested and assimilated by our cells in an effort to produce energy simply for generation of information and matter. Furthermore, this generated information and matter is responsible for the physical characteristics and behaviour we individually possess. All organic molecules naturally present in our food are classified into 4 general categories: carbohydrate, lipid, protein, and nucleic acid. Foods you consume consist of these molecules. The carbohydrates that we obtain from mostly grains, sugars, cereals, potatoes, fruits and vegetables are our body’s main energy source.

This energy will be further synthesized and utilized by our brains, particularly in the form f glucose, in order to generate adenosine triphosphate later used then by our muscles as well as by our cells for the purpose of attaining sustenance in our system. Lipid is usually gained through butter, oil and animal fat. As much as we want to minimize fats in oour system, we need them for the maintenance of our cell membrance as well as for the production of some hormones. 3. Proteins – beans, meat, green leafy vegetables. Most people think of meat when protein is discussed.

True as that may be, there are other means of obtaining your rotein. There’s an array of beans, all of which have protein. Everything from kidney beans to peanuts. We need proteins to maintain our muscles and the components of proteins help us put together almost everything in our bodies – from something as small as markers on our cells and antibodies, to steroid hormones, muscle tissue, hair and nails. 4. Nucleic acids – the genetic material. We consume the cells of an organism. part of our DNA, but eating other organisms breaks down the DNA found in them into its components so they can be ‘recycled’.
