Question

How many nitrogen atoms are present in Lecithin?​

Answer 1

Answer:

It's molecular formula is C55H66NO7P

Explanation:

There fore it will have one nitrogen atom

Answer 2

0.2% of the nitrogen in lecithin is present in this fatty acid form.

• N's top shell has 5 electrons.
• We all know that the most stable arrangement is an octet, which has 8 electrons in the outermost shell.
• Lecithin is generally neutral, thus if N has four covalent bonds, it must have precisely four electrons in its outermost shell, which indicates that it should be N+.
• An example of phosphatidylcholine is shown in the structure (a lecithin phospholipid). To find the "R-groups," you may compare the overall structure with the one shown in the figure. The charge on the nitrogen is unaffected by the "R-groups," though.
• The proton leaves the OH group bound to the phosphorus, creating a negative charge on the oxygen in its place, and is attracted to the nitrogen, creating the positive charge on nitrogen (due to the basic character of nitrogen). Lecithin is an example of a zwitter ion, which is a neutral substance containing positive and negative charges on distinct atoms of the same molecule.
