There's an old saying, you are what you eat in some senses, this is literally true when we eat food, we take in the large biological molecules found in the food, including carbohydrates, proteins, lipids (such as fats), and nucleic acids (such as dna), and use them to power our cells and build our bodies. Essay # 3 synthesis of carbohydrates: 1 from fats: it is certain that the glycerol, portion of fat, which makes up about 10% of the fat molecule, is converted into glucose in the body but the conversion of fatty acid portion of fat molecules to glucose is a matter of dispute specially in animal body as contrast to plants. Carbohydrates, proteins and lipids are all examples of organic molecules many organic molecules are formed of sub units called monomers which join together.
Immunoglobulin g is a type of protein known as an antibody this is the most abundant immunoglobulin and is found in all body fluids each y-shaped molecule has two arms (top) that can bind to specific antigens, for instance bacterial or viral proteins. 23a3 lipids are more suitable for long term energy storage in humans than carbohydrates explain the energy storage of lipids compared to that of carbohydrates 23a4 evaluation of evidence and the methods used to obtain the evidence for health claims made about lipids. There are four main classes of organic compounds namely lipids, carbohydrates, proteins and nucleic acid all the other classes apart but lipids are polymers carbohydrates are made up of carbon, hydrogen, and oxygen and have a general formula of cn(h2o)n. Lipids lipids in general lipids are insoluble in water but soluble in organic solvents, like chloroform lipids are made up of carbon, hydrogen and oxygen lipids have no generalized formula and much less oxygen compared to hydrogen lipids have a high proportion of non-polar carbon-hydrogen bonds, making them hydrophobic fat is a lipid in the solid state at 20oc oil is a lipid in the liquid.
These consist of four types the carbohydrates, proteins, lipids and nucleic acids with each type being made up of its own specific monomers carbohydrates they are often called sugars and they supply a large percentage of energy to animal and human cells. Home a level and ib biology lipids, carbohydrates and proteins lipids, carbohydrates and proteins 45 / 5 hide show resource information galctose is less soluble and is used in the production of glyco- proteins/lipids pentose sugars have 5 carbon atoms, these include dna and rna aqa biol5 essay marking thread/feedback ». Lipids are not water soluble, so they don't affect osmotic potential, making them excellent for long term storage of energy containing twice the amount of energy per unit mass or volume as do either carbohydrates or proteins. - why the structure and function of proteins is essential to living organisms proteins, along with carbohydrates, lipids and nucleic acid make up all life on earth, and without any one of these macromolecules, life on earth would not be able to continue.

Biological polymers: proteins, carbohydrates, lipids share flipboard email print regina bailey is a science writer and educator who has covered biology for thoughtco since 1997 they are carbohydrates, lipids, proteins and nucleic acids these polymers are composed of different monomers and serve different functions. Carbohydrates, proteins, and fats supply 90% of the dry weight of the diet and 100% of its energy all three provide energy (measured in calories), but the amount of energy in 1 gram (1/28 ounce) differs: 4 calories in a gram of carbohydrate or protein 9 calories in a gram of fat. Carbohydrates, lipids and proteins 321 distinguish between organic and inorganic compounds organic compounds are compounds that are found in living organisms and contain carbon. Often covalently bonded to proteins and lipids on cell surfaces and act as recognition signals carbohydrates formed by linear or branched combination of monosaccharides central dogma of molecular biology: • dna can reproduce itself (replication.
Whichever essay subject supermolecule you pick, you will necessitate to sketch the assortment of constructions in that household of supermolecules it may be utile to utilize diagrams for this, you will so necessitate to explicate how and where they are used in the cell and, where appropriate nexus supermolecule construction to map you will besides.

First of all, it is pretty easy to see that proteins, nucleic acids, carbohydrates, and lipids all have some common elements that are combined in different ways the common elemental ingredients.
The main substances found in every cell are a combination of lipids, carbohydrates, nucleic acids and proteins each of these substances plays a different role in the body, and all of them must either come from the diet or be manufactured using other chemicals in the body. Main difference – carbohydrates vs lipids macronutrients are the nutrients required in large amounts in the diet they can be divided into three categories they are carbohydrates, proteins and lipidsa carbohydrate consists of carbon (c), hydrogen (h), and oxygen (o) atoms, usually with a hydrogen–oxygen atom ratio of 2:1 (as in water. Why only proteins are used as bu show more why carbohydrates and lipids basically used as a sources of energy why only proteins are used as building blocks of all the creations assignment help biology why carbohydrates and lipids basically used as a sources of format and features approximately 275 words/page all paper formats (apa.
