### Is soy lecithin the same as peanut lecithin?

The most different point is the composition of lecithin.
Peanut lecithin contain:
- PC (phosphatidyl choline)=49 %
- PE (phosphatidyl inositol)=16 %
- PI (phosphatidyl ethanolamine)=22 %
Soybean lecithin contain: PC=21 %, PE=22, PI=19 %, PA
(phosphatidic acid)=10 %,
PS (phosphatidyl serine)=1 %, Glycolipid=12 %
This is a simple answer.
The chemical composition of lecithin is dependent on the source;
soy lecithin and peanut lecithin are not identical.

### Which is the recursive formula for the nth term in a geometric sequence?

You need to know two numbers to completely describe the
geometric sequence: the starting number, and the ratio between each
number and the previous one.
When you use recursion, you always need a "base case",
otherwise, the recursion will repeat without end.
In words, if "n" is 1, the result is the starting term.
Otherwise, it is the ratio times the "n-1"th term.
The following version is appropriate for a programming language
(written here in pseudocode, i.e., not for a specific
language):
function geometric(starting_number, ratio, term)
if term = 1:
result = starting_number
else:
result = ratio * geometric(starting_number, ratio, term - 1)

### How many different types of Phospholipids are there?

Phospholipids are classified according to alcohol they possess
so they are classified into three categories:
1) Glycerophosphatides (Glycerol-alcohol based
phospholipids):
a) Phosphatidic acid (phosphate) (PA)
b) phosphatidylcholine (lecithin) (PC)
c) phosphatidylinositol (PI) &
d) phosphatidylethanolamine (cephalin) (PE),
2)Phospho-inositides (inositol-alcohol based phospholipids):
a) phosphatidylinositol phosphate (PIP)
b) phosphatidylinositol bisphosphate (PIP2) &
c) phosphatidylinositol triphosphate (PIP3),
3) Phospho-sphingosides (sphingol-alcohol based
phospholipids):
a) Ceramide phosphorylcholine (Sphingomyelin) (SPH)
b) Ceramide phosphorylethanolamine (Sphingomyelin) &
c) Ceramide phosphorylglycerol (Cer-PE).
