Cell Bio People.  Does anyone know a site where I can get molecular structures for fruits?

Hate to break it to you but fruit doesn't have a molecular structure. No more than an elephant or a house has a molecular structure. These things are complex muli-molecular constructs, not molecules.\n\nYou can certainly find out the molecular structure of fruit components. \n\n95% of most fruit is just water, H2O. That should be easy enough for you to find on the web.\n\nOf the remaining 5% around 60% will be cellulose. That is a fairly simple polysaccharide. And again the molecular structure is easy to find on the web now that you know the name.\n\nOf the 2% remaining 99% will be sugars. Primarily fructose in most cases but also glucose and a range of other di and monsaccharides. Once more, the molecular structuresof these substances have been well studied and are freely vailable on the web..\n\nOf the 0.01% left over 50% at least will be the lipids and liposaccharides of the cell walls. These vary considerably between fruit species. But once again there is welathof information on the web if you search for "cell membrane lipid structure" or similar and add the species name you are interested in.\n\nMost of the rest will be various enzymes and other proteins. These also vary with the fruit, but they have also  been extensively studied. Some, like papayin and those enzymes associated with the TCA cycle are easily found on the web.\n\nThe rest, less than 0.001 of most fruit, will be various vitamins (molecular structure widely and eaily available on the web) and the esters, ketones, terpenes, alcohols and so forth that produce the characterictic odour of the fruit. SOme of these have been widley studied, often by the food flavourings and cosmetics industries. \n\nYou should be able to find a lot of info by doing a search on those molecules + the species you are dealing with. I;ve oncluded a few example earches below. They readily return results like \n\n"Composed of one or more aromatic benzene rings with one or more hydroxyl groups (C-OH). This enormous class includes numerous plant compounds that are chemically distinct from terpenes. Although the essential oils are often classified as terpenes, many of these volatile chemicals are actually phenolic compounds, such as eucalyptol from (Eucalytus globulus), citronellal from (E. citriodora) and clove oil from Syzygium aromaticum."\n\nand \n""Bitter orange oil", expressed from the peel, is in demand for flavoring candy, ice cream, baked goods, gelatins and puddings, chewing gum, soft drinks, liqueurs and pharmaceutical products, especially if the water-or alcohol-insoluble terpenes and sesquiterpenes are removed. "\n\nThat sounds like the type of thing you want. It's quite easy to find if you know where to start.

YOU can co relate krants anatomy(presence of chloroplasts in bundle sheath cells) and high yield of starches in rice plant It needs some research on Internet .But otherwise it is a good topic for any seminars

That's sort of a broad request.  Are there any specific types of structures that you are looking for?  I know of a good site that has 3D models of proteins, structures derived from X-ray crystallography studies:\n\nhttp://www.pdb.org/pdb/advSearch.do\n\nJust chose 'structure description' as your 'query type' and enter the name of a protein into the search field.  They have quite an extensive database.\n\nThe Univ of Mass also has links to some other structures (DNA, antibodies, etc).  The images were generated by Chime, a powerful (and unfortunately not free) software program for generating 3D structures.\n\nhttp://www.umass.edu/microbio/rasmol/\n\nHope this helps!

I recommend the following link:\nhttp://www.amazon.com/Phytochemical-Methods-Modern-Techniques-Analysis/dp/0412343304\n\nYou will need to purchase a lab guide or consult with a Life Sciences Dept. for further assistance

Go to "protein" on wikipedia ( put, protein, in address bar ) then scroll down to "synthesis", for the process. It is too  long a story for my typing skills. The wiki article is not too technical.

Too many to list and explain here, without copying and pasting  --and why should I do all your uni work for you? ;-)\n\nI will recommend a couple of good text books through.  Well worth a purchase or just get them on loan from your library...\n\nAlberts et al, Molecular Biology of the Cell\nStryer, Biochemistry\n\nIt's been since I bought mine.  Think I got editions 2 & 7 back in 1996 and I know both have been updated a couple of times since.  These are still a GREAT basic resourse for this sort of question.

I did something like that for a science project too. Only mine was a cake with decorations that made it look like a cell... ^_~\nWe also have an actual model of animal and plant cells in my class, but those were mail-ordered. For a really realistic one, you're gonna need some special parts.\nYou can do it more easily with a styrofoam ball of a reasonable size (or a styrofoam cube if you're doing a plant cell), another smaller ball (for the nucleus), I'm not sure what you could use for mitochondria.... Hit a craft store and get creative. There's plenty of stuff out there just waiting for you to find it. Pom-poms could be used for the vacuoles I guess, and you could coat the larger ball with playdoh for the membrane. I'm sure you'll think of something. Remember this when you're working: hot glue guns are your friends.\nJust remember to include all the components:\nNucleus, cytoplasm, vacuoles, mitochondria, cell membrane, endoplasmic reticulum, and the two extra plant parts: chloroplasts and that extra thick wall whose name in English I cannot recall... xD\nIf I can make a sponge cake into an animal cell with some Fuzzy Peaches, Rockets, jelly beans and chocolate sprinkles, I'm sure you can make a styrofoam ball into something just as good or better. Best of luck!

http://www.chembio.uoguelph.ca/educmat/Chm258/enzplots.htm\n\nsee if that site helps any.  If not.  I can give you a very confused book answer from my Biochemical Calculations text.  It might be hard to explain online though, sorry.  The text I use (as a graduate student--biotechnology) is Biochemical Calculation 2nd Ed. by Irwin H. Segel, it's a great book.
