Macromolecules Biologically‚ there are four general types of macromolecules or biomolecules. They are carbohydrates‚ proteins‚ lipids and nucleic acids. Each of these plays an important role in maintaining life among living creatures and each is a piece of the elaborate puzzle of metabolism. Each has a different chemical composition and interacts with other molecules differently. Most of these biomolecules come from food sources and we are therefore already familiar with them. Without a

structure which is why they function in these ways. These molecules are known collectively as macromolecules‚ these molecules are grouped into four main categories which each have there own structure. These structures are the key to the macromolecules functions as each of them do a specific task in the body. Macromolecules are grouped into carbohydrates‚ nucleic acids‚ proteins‚ and lipids. In most cases macromolecules are polymers‚ which is a long molecule which are made by linking together a large number

diverse macromolecules are different because of the structure of these respective monomers. An exceptionally large assortment of macromolecules gets produced. While the polymers are accountable for the molecular exceptionally of an organism. The joint monomers are virtually universal. The difference in the form of the macromolecules are responsible for the molecular diversity. The variation that occurs both within an organism and among plants can be traced to the difference in macromolecules. Also

Macro molecules A macromolecule is a very large molecule commonly created by polymerization of smaller subunits. In biochemistry‚ the term is applied to the three conventional biopolymers (nucleic acids‚ lipids‚ proteins and carbohydrates)‚ as well as non-polymeric molecules with large molecular mass such as lipids and macrocycles. The individual constituent molecules of macromolecules are called monomers(mono=single‚ meros=part). Usage The term macromolecule was coined by Nobel laureate Hermann

Brittney Humphries. Title: Testing for the Presence of Starches‚ and Proteins Purpose: To test for the presence of starches and protein macromolecules‚ to introduce the concept of variations in chemical compounds. Hypothesis: If biuret is blue after a test for protein‚ then it is a negative result because biuret reagent is blue to begin with. If a solution is pinkish purple‚ or purple‚ then the test for protein is positive. The test solution for starches is yellowish brown. If any substance

Title: Hydrolysis of macromolecules Abstract: This lab was designed to teach the process of “hydrolysis”‚ a chemical reaction in which water is added to a polymer‚ breaking its bonds and forming smaller molecules. A hydrogen cation and a hydroxide anion (which once formed water) break apart and attach themselves to the ends of shorter polymers. Hydrolysis plays an important role in our lives and in the lives of every living thing on earth. Living organisms rely on digestion (hydrolysis)

Deoxyribonucleic acid (DNA) is the fundamental molecule of life encoding the genetic code for the development and functioning of every living organism and a large variety of viruses. RNA‚ proteins‚ and DNA are the main macromolecules‚ which are necessary for every form of life. The genetic system is encoded in the form of a sequence of nucleotides (guanine‚ adenine‚ thymine‚ and cytosine)‚ which are denoted by the letters G‚ A‚ T‚ and C. Most DNA molecules consist of double-stranded helices‚ composed

Macromolecule Report Monomer units of biological macromolecules have heads and tails. When they polymerize in a head-to-tail fashion‚ the resulting polymers also have heads and tails. These macromolecules are polar because they are formed by head to tail condensation of polar monomers. Making Glucose: Green plants manufacture glucose through a process that requires light‚ known as photosynthesis. This process takes place in the leaf chloroplasts. Carbon dioxide and water molecules enter a sequence

Title Food Lab Abstract The aim of this report is to see if the any of the four food apple sauce‚ carrot juice‚ cracker juice‚ and turkey juice contain protein‚ starch‚ or sugar. Between these four foods two are positive for sugar which are apple sauce and carrot juice. Sugar is an organic molecule of carbohydrate and so is starch. The starch was positive in two of the foods which are cracker juice and carrot juice. Protein is its own organic molecule and only one food tested positive for protein and
