Yes. It serves as a Humectant.
There is no definite answer to this question since Lecithin (which is an emulsifier) may be derived form either plant (i.e. soy lecithin) - or animal source. Here in Germany it is specifically written if the lecithin is derived from soy beans (= soy lecithin). If only "lecithin" is written on the product, one has to ensure (f.e. by contacting the producer) whether its derived from animal or plant-source. See more here: http://en.wikipedia.org/wiki/Lecithin
Lecithin can come from two main sources; soy or eggs. Clearly if you have a soy allergy, eating soy lecithin is unwise. Luckily, if lecithin is from soy, it must be labelled "soy lecithin" on the packaging. Eating egg lecithin should present no problems. I should point out that the vast majority of regular chocolate bars contain soy lecithin rather than egg; lecithin-free chocolate is a specialty product which can sometimes be found in specialist chocolateries or health-food stores.
Lecithin supplements are either sold in a liquid or granular form. Lecithin has a mild light taste that is not offensive when eaten alone.
Lecithin is a combination of phospholipids that naturally occur in soybeans. Lecithin gums are obtained from soy oil after the oil has been extracted from the soybean flakes. Lecithin is removed from the soybean oil using a steam precipitation process. Precipitate is spray dryed to be transformed into Lecithin powder for use as ingredient in dry foods and it has the same applications as the liquid Soya Lecithin
many studies of the effects of lecithin had faulty methods, and the few good studies proved that lecithin was not effective in lowering cholesterol.

I have noticed that when I take lecithin granules at night I do not have my regular morning movement.
Although lecithin is made from oils, animal fat may also be used.
