Lactose, a sugar in milk, is composed of one glucose molecule joined by a glycosidic linkage to one galactose molecule. Lactose is classified as a disaccharide
It becomes milk sugar or more commonly known as lactose. One glucose monomer and one galactose monomer makes the disaccharide lactose.
Cows milk contains lactose (about 4.7%), which is a sugar molecule comprising one glucose molecule linked to one galactose molecule. Lactose is unique to milk. So, in one ounce of milk, approximately 1/20th of it would be 'sugar', i.e. lactose, about 1.5 g.
One synonym for glucose is blood sugar.
Glucose is the main sugar produced in photosynthesis.
== == Monosaccharides are one-molecule sugars and those commonly found in food are: Glucose (dextrose or blood sugar) Fructose (fruit sugar) Galactose (occurs mainly in milk) Polysaccarides (complex carbs) are made up of simple sugars (monosaccharides) or their derivatives linked together in different ways. Starch is an example of polysaccharide or complex carbohydrate. Let's not forget those Disaccharides! Disaccharides are two monosaccharides linked together. Those common to food always contain at least one glucose molecule. Sucrose (table sugar) = glucose + fructose Lactose (milk sugar) = glucose + galactose Maltose (malt sugar) = glucose + glucose
Sugar is a broad term that refers to a group of carbohydrates, including simple sugars like glucose, fructose, and sucrose. Glucose is a type of sugar that is the main source of energy for the body's cells and is found in many foods. So, all glucose is sugar, but not all sugar is glucose.
Glucose is the kind of sugar that circulates in the blood. For example, lactose (sugar found in milk), is a disaccharide (ie two linked sugar molecules) made up of one glucose molecule and one galactose molecule. Galactose is almost like glucose, but it will be changed into glucose in the liver and then released into the blood. All carbohydrates, including starches and grains, eventually get broken down and converted into glucose molecules, which are then released into the blood.
One tiny bit of glucose is equal to a whole bowl of sugar. They are the same thing but glucose is worse for you.
Aspartame is not a naturally occurring sugar. It is a low-calorie artificial sweetener used as a sugar substitute in many foods and beverages.
Lactose and glucose are not the same. Glucose is a mono-saccharide (composed of one sugar molecule) while lactose is a di-saccharide (2 sugar molecules; one of which is a glucose molecule).
A single glucose molecule is called monosaccharide.
