5.3 Summary

Lipids are inablitiy to mix with water and it is a typical of the class of water, which they avoid compounds.

In 5.3 it talks about how lipids includes fats and steriods. In 5.3 it also talks about the characteristics of lipids, fats, and steriods. As you already know lipids are inablitiy to mix with water and it is a typical of the class of water, which they avoid compounds. And also hydrophobic means water-fearing, which water-avoiding molecules.

Fats include three-carbon backbone which is called glycerold. Glycerold is also attached to three fatty acids, the three fatty acids contain a long hydrocarbon chains. Also there are unsaturated fats which are solid at room temperature.

Steroids are a kind of lipid molecule with a carbon skeleton which forms four fused rings. Steroids have a kind of core set of four ring which makes the different from the of kind of functional groups which are attached to the ring. Therefore steroid are put into a class which they are hydrophobic. Cholesterol is an essential molecule which is found in the membranes that surround the cells in your body.
