What are lipids and what are the major classes of lipids?

A: Covalent-electrons between atoms are sharedIonic-an electrostatic attraction between two oppositely charged atomsHydrogen-a relatively weak bond that holds two or more polar covalent compounds together

B: Organic substances that are relatively insoluble in water and are hydrophobic (water "hating")Fatty acids Triglycerides Phospholipids

C: genetic disease caused by a mutation in the genes that code for the enzymes that either stabilize or make collagen.

D: the way these genes are selected for or against in nature to increase the reproductive survival (or fitness) of a population is NOT at all random
