PROTEIN TRANSLATION 1. Initiation Translation To begin translation: large and small ribosomal subunit‚ along with the initiating tRNA‚ assembles onto the mRNA 2. Translation Elongation The next amino acyl-tRNA enters the ribosome at the A site The amino acid at the P site is transferred to the tRNA at the A site. The ribosome moves one codon farther along the mRNA‚ releasing the empty tRNA through the E (exit) site. The A site is free for the next incoming RNA. The cycle is repeated as the

Lipid Digestion The process of mastication is our only conscious act in the digestion of the foods we consume. After that‚ it’s out of sight‚ out of mind; but should it be? What does it take to transform that last swallow into the energy our body needs to sustain itself? In the case of lipid digestion‚ the real magic occurs throughout the gastrointestinal tract with a synergistic collaboration from the accessory organs: the liver‚ gallbladder and pancreas. Understanding the whole process of digestion

Proteins are also essential nutrients for the human body. They are important in body tissue‚ and can also serve as a fuel source. Every cell in the human body contains protein. The basic structure of protein is a chain of amino acids. We need protein in our diet to help our body to repair cells and make new ones. The human body needs a lot of amino acids to maintain good health. Protein is also important for growth and development in children‚ teens‚ and pregnant women. Proteins are polymer chains

Lipids are made up of carbon‚ hydrogen and oxygen (phospholipids also contain phosphate) and are found in a wide variety of organisms from bacteria to eukaryotes where they perform a wide variety of useful functions. This essay will expand on these functions to describe the role of lipids. There are several types of lipid including triglycerides‚ steroids‚ waxes and phospholipids. Triglycerides are made up of three fatty acids combined with glycerol by an ester linkage meaning they are predominantly

Carbohydrates For my health project I did carbohydrates. They are the bodies energy source. Carbohydrates supply the body with the energy it needs to function. They are found almost exclusively in plant foods‚ such as fruits‚ vegetables‚ peas‚ and beans. Milk and milk products are the only foods derived from animals that contain a significant amount of carbohydrates. Carbohydrates are divided into two groups‚ simple carbohydrates and complex carbohydrates. Simple carbohydrates‚ sometimes

Where ’s the Protein? Proteins‚ which are constructed from amino acid monomers‚ are considered one of the four major macronutrients needed by the body‚ along with carbohydrates‚ lipids‚ and nucleic acids. Only the first three nutrients listed require delicate balancing. One must consider the sources from which he or she receives those required nutrients. Carbohydrates from fruits‚ vegetables‚ and grains; lipids from oily animals such as fish or plant foods like avocados; and proteins from meats‚

We have four important macromolecules; carbohydrates‚ lipids‚ proteins‚ and nucleic acids. From these four‚ the macromolecule I chose for this assignment was carbohydrate. Carbohydrates branch off into three main categories; monosaccharides‚ disaccharides‚ and polysaccharides. I decided to focus on disaccharides‚ specifically sucrose. Sucrose is more commonly known as table sugar. It has a chemical formula of C12H22O11. It is physically described as a white‚ odorless (although when heated‚ it may

Carbohydrate presentation: SCI 241 Sovanna Ath What is Carbohydrate? * Source of energy * Effects of too much carbohydrates A CARBOHYDRATE IS the ideal source where your body get your energy from. Even though carbohydrates are good for your body too much of it can upset the delicate balance of your body’s blood sugar level which can result in fluctuation in energy and mood that leave you feeling irritated and even tired. It is also better for your body to have a balance of carbohydrates

“Denaturation of Proteins” Denaturation is a process in which proteins or nucleic acids lose the tertiary structure and secondary structure which is present in their native state‚ by application of some external stress or compound such as a strong acid or base‚ a concentrated inorganic salt‚ an organic solvent (e.g.‚ alcohol or chloroform)‚ or heat. If proteins in a living cell are denatured‚ this results in disruption of cell activity and possibly cell death. Denatured proteins can exhibit
