What knowledge have you connected witht past knowledge?

I have connected many things in biochemistry with my past knowledge. Having the knowledge from science classes I realized that all these courses have something in common that binds them all together. For insistence, saturated and unsaturated fats. Not only in our science courses we hear about these fatty acids but everywhere we go such as, in food we eat, diets, and supermarkets. Saturated fat consists of triglycerides and had all single bonds, it does not have any double bonds. It has a chemical makeup in which the carbon atoms are saturated with hydrogen atoms. Unsaturated fat is a fatty acid in which there is at least one double bond within the fatty acid chain. This fatty acid is made from animal products which lowers LDL cholesterol. Also, there is a hydrogenation process that adds hydrogen's to make double bonds single, making unsaturated fatty acids to saturated.
