carb:\n1. basically, carbohydrates have carbon, hydrogen and oxygen. the ratio of hydrogen to oxygen is 2:1\n2. rice, starch subtances like potatoes\n3. carbs are for energy\n\nlipids:\n1. also carbon, oxygen and hydrogen.. but the ratio of hydrogen to oxygen is more than 2:1\n2. butter, margerine, oil\n3. also as extra source of energy.. lipids can be a heat insulator of the body\n\nproteins:\n1. carbon, hydrogen, oxygen and nitrogen are the main elements... other element which may be found is sulphur...\n2. beans, peanuts, meat, milk, fish\n3. proteins are something like the building blocks for our body to grow...

Carbohydrates are the main food source for many animals. \n\nIt's pretty easy to get a lot of carbohydrates. I would suggest focusing your diet on complex carbohydrates as they tend to be in sources with more fiber. Examples are oatmeal, whole wheat bread/pasta/etc., and starchy vegetables.\n\nLook on the "Nutrition Facts" label on foods to see their carbohydrate content.

A protein and a carbohydrate...\n\nA glycoprotein is a macromolecule composed of a protein and a carbohydrate (an oligosaccharide). The carbohydrate is attached to the protein in a cotranslational or posttranslational modification. The addition of sugar chains can happen at either asparagine, and is termed N-glycosylation, or at hydroxylysine, hydroxyproline, serine, or threonine and is termed O-glycosylation. Possible carbohydrates include glucose, glucosamine, galactose, galactosamine, mannose, fucose, and sialic acid.

Many lipids are glycolipids - a lipid bound to a carbohydrate.  These are often components of cell membranes.

I'm a writer for various fitness publications and here's one I wrote on the subject of carbohydrates that should help you a great deal to understanding this confusing subject:\n\nhttp://www.truthaboutabs.com/glycemic-index-carbohydrates.html\n\nAlso, here's some of the healthiest foods on the planet listed in this other article I wrote:\n\nhttp://www.truthaboutabs.com/hard-body-nutrition.html\n\nBest wishes

To know what carbohydrates are made up of, we must classify them first.\n1.Monosachharides-simple sugars like glucose constitute them, each glucose molecule binds with another one by glycosidic bonds to form glycosides.\n2.Disaccharides-eg, sucrose....composed of 2 monosaccharides\n3.Oligosachharides-eg. blood group antigens, composed of 2 to ten monosachharides\n4.Polysachharides-eg. glycogen-composed of more than 10 monosaccharides\nThey can also be classified as aldoses or ketoses, if the reactive group is CHO then its aldose, if C=O then ketoses.\nGlucose is aldose, Fructose is ketose.If u talk of starch, its a polysachharide constituting carbohydrates like amylose and amylopectin.So we have carbon, hydrogen and oxygen compounds involved.\nThat i think is enough about the structure of carbohydrates in context with biology, but do learn to draw the structures.\nIf they contain nitrogen, or aminio group then they are not carbohydrates, they are already derivatives of carbohydrates-glycoproteins, proteoglycans(mucopolysachharides; one example is glucosaminoglycans)

Protein and carbohydrates.  Eat a medium meal, you want energy, but not a lot of sugar.

Food, carbs are a big part of the energy that our body needs.

Vegetables contain all of these organic compounds in differing amounts.  Carbohydrates as both sugars and copious amounts of cellulose.  Proteins in the cells, but not generally as large structual components (obviously no huge protein sinks like muscles.)  Lipids as cell membranes etc....  All living things have nucleic acids, even viruses.
