      Hi, I have a question regarding fat levels in plants. I was wondering why is it that plants have much lower levels of fat than animals. Could it be because plants do not have chlolesterol?

      If anyone could please reply to me with some insights, that would be great. Thanks!

      Maybee because plants are more efficient at creating energy?

      think about the roles that fats play in animals, and ask yourself if that would make sense in a plant…

      But the strange thing again…why plant fats is always have a double bond of the carbon chain while animal fats are always single bond??

      I think we can’t answer this question.
      We can answer why FAME is that. It is universal truth

      That’s not entirely true, coconuts have some of the highest concentration of saturated fats.

      Soy and mushrooms are used for replacement of meat in vegetarian diets.
      Is that because of the proteins or fats they contain?

      Mushrooms provide vitamin B. I don’t think they’re that good a source of protein.

      quote mithrilhack:

      But at least there must be a double chain in the carbon chain..

      Dr. S.M. Alam and Rizwan Manzoor said:
      Mushrooms are used as food as well as medicine since time immemorial. The edible variety contains a high percentage of protein, all indispensable amino acids, and vitamins B-complex and other biochemical compounds. This vegetable is also a food source of dietary fibre whose quantity present is much higher than the crude fibre. The protein value of mushroom is double that of cabbage, potatoes and asparagus, four times that of tomatoes and carrot and six times that of oranges.
      Now we return the topic “fatty acids in plant tissue”
      Why they accumulate most in seed?

      I guess it depends on the mushrooms, I’m referring from the package of white mushrooms from my grocery store.


      @victor

      If it’s a saturated fat, there’s no double bonds according to the definition. All carbon atoms will have the maximum number of hydrogen attached.

      Certainly the nutrition s’ concentration depend on genus .
      Do you know some FAME s’ database?

      Plants acumulate energy under the form of starch. Only a small number of plants acumulate fats and that is only in their seeds(example: sun-flower). Something like 99% of the fat from a plant is in the membranes of cells.
      Animals accumulate energy under the form of glycogen. If they eat too much or eat too many lipids however, and the glycogen capacity is exceded, the body “stockpiles” energy under the form of tryglicerides in adipose tissue. Some animals have learned too use this function-ex:bears eat much more than they consume during summer in order to get fat and to able to hibernate all winter.
      Or something like that…. 😆

      Why do you say “Something like 99% of the fat from a plant is in the membranes of cells”. Please give the references if you don’t know exactly

      do you mean that animals have fat as storage, and plants have got starchy parts (like potatoplants have potatoes) to do the same job?
      (just a summary for the less educated among us… 😳 )

      @har0bed1813
      No, animals have glycogen. only if the glycogen capacity is exceded, the energy is stored into lipids
      @mothroc
      No, i don’t have the reference. I have read about 20 botany books in my life, and looked around another 20-25…

      For the same reason as in animals, plant embryo of spermatophytes (seed plants) doesnt do photosynthesis and doesnt make own organic compounds for chemical energy thus to germinate it draws chemical energy and material for own from organic compounds like lipids or proteins which are in the reserve tissues. In other words tissues in seeds have evolved (endosperm, perisperm or own embryo tissue too in matter of fact) in order to nourish plant embryo during its germination before the plants start to make organic compounds from anorganic by the photosynthesis.
