    The topic I have chosen is Osteoporosis and how it is related to a deficiency of calcium. Throughout my human nutrition course the importance for proper nutrition and adequate dietary supplements has been constantly emphasized. Nutrition is the science that deals with food and how the body utilizes it. All living things need food to live. Food supplies energy, which people need to perform certain actions and bodily functions. Food also provides substances that the body needs to build and repair ...

  • Amino Acids Stress Hormones
    1,374 words
    In 1975, Dr. John Hughes and Dr. Kosterlitz discovered Endorphins. It has been confirmed that Endorphins have both neurological and spinal effects. Twenty different types of Endorphins have been discovered in the nervous system. The most effective, beta-endorphin, which gives the most euphoric effect to the brain, has been found to be composed of 31 amino acids. The word Endorphin is abbreviated from 'endogenous morphine' which means morphine produced naturally in the body. Endorphins are renown...

    Deoxyribonucleic acid and ribonucleic acid are two chemical substances involved in transmitting genetic information from parent to offspring. It was known early into the 20 th century that chromosomes, the genetic material of cells, contained DNA. In 1944, Oswald T. Avery, Colin M. MacLeod, and Maclyn McCarty concluded that DNA was the basic genetic component of chromosomes. Later, RNA would be proven to regulate protein synthesis. DNA is the genetic material found in most viruses and in all cel...

  • Mad Cow Disease Amino Acids
    1,495 words
    Who would of thought that eating hamburgers, steaks and drinking milk could produce an epidemic disease? These types of food are frequently eaten for their appealing tastes and nutritional values. The discovery of Creutzfeld Jakob Disease (CJD) has been a long and remarkable one. The cause of this disease is a mutated prion protein within the brain that can be either inherited or acquired. These mutations create sponge like holes that destroy the brain. As a result, the disorder gives both behav...

  • Amino Acids Living Organisms
    979 words
    Proteins are the macromolecules of life. Discovered in 1838, proteins are recognized as a large number of superior organic compounds that make up living organisms and are essential to their functioning. The term protein comes from the Greek word proteins or primary. Proteins have many different properties and function in a variety of ways. They can function as a building material, in teeth, bones and muscles, and they can serve as enzymes, hormones, and neurotransmitters. Its functions are the m...

  • Amino Acids Dna Molecule
    1,152 words
    Introduction Deoxyribonucleic acid is contained in all cells. The structure of DNA makes gene transmission possible. Since genes are segments of DNA, DNA must be able to make exact copies of itself to enable the next generation of cells to receive the same genes. The DNA molecule looks like a twisted ladder. Each "side" is a chain of alternating phosphate and deoxyribose sugar molecules. The "steps" are formed by bonded pairs of purine-pyrimidine bases. DNA contains four such bases the purines a...

    A gastric gland is a tubular structure in the vertebrate stomach that secretes gastric juices. The gastric glands have three types of cells that secrete different components of the gastric juice. One of them is being a chief cell, which is a rust color and is an inactive form of the digestive enzyme Pepsin. Pepsin begins the digestion of proteins in food. Pepsin is a Peptidases, which is an enzyme that breaks peptide bonds of proteins. Pepsin is found in the mucosal lining of the stomach that br...

  • Gram Positive And Negative Bacteria
    828 words
    Gram Positive and Gram Negative Bacteria It is a well-known fact that bacterial cells, like plant cells, are surrounded by a cell wall. However, few people know that their cell walls are quite different. Bacterial cell walls are made up of polysaccharide chains linked to amino acids. At the same time, plant cell walls are made up of cellulose, which contains no amino acids. In the same way, bacterial cell walls themselves differ from one another. Scientists distinguish two types of bacteria cell...

    Physiology In Cell Communication Cell Communication Physiology In the human body there are many parts that work together in order for everything to function properly, but even these parts need to have a way to know what to do. This is where cell communication comes into play. Tiny cells in the body contain astounding networks that allow for this communication. Scientists are discovering why these messages from cell to cell are so efficient, and this could lead to new therapies for diseases. In t...

    DNA: The Making Lyle Sykes For more than 50 years after the science of genetics was established and the patterns of inheritance through genes were clarified, the largest questions remained unanswered: How are the chromosomes and their genes copied so exactly from cell to cell, and how do they direct the structure and behavior of living things? This paper will discuss those questions and the people that answered them. Two American geneticists, George Wells Beadle and Edward Lawrie Tatum, provided...

    Today, weve realised that the very first life on Earth was indeed originated from abiotic surroundings. In fact, organic molecules have been successfully generated from abiotic elements by scientists To understand how this creation of life from abiotic material occured, we have to consider a critical idea. Life originated from its abiotic surroundings. Thus, it is important for us to learn about the physical and chemical environments of the primitive Earth. The atmosphere of primitive Earth cons...

    892 words
    A mutation is a change in the genetic material that controls heredity. The genetic material is contained in chromosomes, which are divided into genes. Point mutations involve single genes and occur by substitution and insertion or deletion of a single base in DNA. Insertions or deletions, referred to as frameshift mutations, shift the reading of the code by one or more bases so that all amino acids produced after the addition or deletion are affected. Translation is a series of complex biochemic...

    The Protein Site Protein Synthesis The process of Protein Synthesis involves many parts of the cell. Unlike other similar productions, this process is very complex and precise and therefore must be done in proper sequence to work effectively. The slightest error during this process could cause the action to experience difficulty or even fail. For example, in the production of starch, glucose molecules are combined to be stored and eventually utilized as usable chemical energy. The cell can break...

    Proteins are some of the most essential compounds on the planet. They perform a variety of tasks ranging from muscle contraction to fighting diseases. Over 50 % of the dry weight of organisms are made of proteins; this is because things like your nails and hair are made of proteins. Proteins are also components of biological membranes, and they help regulate the passage of molecules through the membranes. This is all very important to the body, but the most important function, by far, is their u...
