Although familial Alzheimer's disease is responsible for a small minority of cases of Alzheimer's disease, it is important, not only for the families with it, but also for what we can learn about all of Alzheimer's disease from it.
Simple syrup. A basic sugar-and-water syrup used by bartenders as a sweetener to make cocktails. Simple syrup is made by stirring granulated sugar into hot water in a saucepan until the sugar is dissolved and then cooling the solution. Generally, the ratio of sugar to water can range anywhere from 1:1 to 2:1 by weight, and similarly by volume due to air in the granulated sugar.
When basic sugar (or sucrose) is inverted, it is broken down into the two basic elements that make it up: glucose and fructose. Inverted sugar syrup is produced either unintentionally, by adding specific ingredients to a recipe, or intentionally to make a sugar syrup that has many advantages in baking. Inverted sugar syrup is often made by using basic sugar syrup, also called simple syrup, which is a mix of water and sugar that is slowly cooked and then boiled for about a minute to produce a liquid.
