Another type of organic compound is lipid. It has the same function of carbohydrates which is store energy. However, it has other functions like carries messages and forms cell membrane. Actually, it also consists with a small unit called fatty acids.
Protein is a paramount organic compound as well. It is constitute by amino acids. The major functions of it is help cell keep shape, make up muscle, speed up chemical reactions, and a function that is the quite similar with lipids which is carry messages or material.
The last kind of organic compound I want to introduce is nucleic acids. A familiar example of it is DNA and RNA. Right, it is a significant material to passes instructions from parents to offspring. Nucleic acids are building up with nucleotides which have three smaller molecules called sugar, phosphate group, and nitrogen base. On the other hand, nucleic acids help make proteins and contain instructions for proteins.
These are four kinds of organic compound I want to recommend. It is the foremost organic compounds we have to know and remember.
