True or False If a linear monosaccharide is designated as beta this means that the OH group on the anomeric carbon is on the same side as the last carbon of the molecule?

False cuz alpha and beta are only assigned to cyclic molecules...

What is an anomeric carbon?
In cyclic form of monosaccharide two forms are possible depending upon the position of -OH group,if it is present below the plane it is known as alpha position and if it is above the plane ,it is known as beta position. The two diastereomers are called anomers.the hemiacetal or hemiketal carbon is called as anomeric carbon.for examplein glucose, C-1 carbon is known as anomeric carbon.
What do monosaccharide and monosaccharide makes?
Carbon, hydrogen and oxygen
How many carbon molecule are there in a molecule of glucose?
Glucose (C6H12O6) is a monosaccharide that contains twelve hydrogen atoms, six carbon atoms and six oxygen atoms. A glucose and fructose molecule combine to create a sucrose molecule.
What is monosacchrides?
When the number of carbon atoms in a molecule is low (from three to seven), then the carbohydrate is a simple sugar, or monosaccharide.
How many atoms are carbon in a molecule of glucose?
Glucose (C6H12O6) is a monosaccharide that contains twelve hydrogen atoms, six carbon atoms and six oxygen atoms. A glucose and fructose molecule combine to create a sucrose molecule.
What is a monosaccharide structure?
Monosaccharide's consist of only one sugar molecule. (Its the basic molecular unit of all Carbohydrates). Most of them have a carbon backbone that ranges between three to seven carbon atoms. Those carbon atoms also have a hydrogen and a hydroxyl group linked to them.
Structure of monosaccharides?
C6h12o6 Sex carbon atom, twelve hydrogen and six oxygen atoms are united to form one molecule of a monosaccharide
What is alpha and beta linkage in the joining of sugars in a carbohydrate?
The beta linkage indicates that the OH group of the anomeric carbon of the cyclic hemiacetal lies on the same side of the ring as the CH2OH group. The alpha linkage indicates exactly the opposite - the OH group of the anomeric carbon lies on the opposite side of the ring as the CH2OH group. The anomeric carbon refers to the carbon group where the new steriocenter was created to form the ring. (generally carbon 1 in a ring).
What is the functional group on the anomeric carbon of glucose when it is in the open chain form?
Carbonyl group
What is a reducing group?
The reducing end of a carbohydrate is found at the anomeric carbon. For glucose, this would be Carbon #1 (C-1).
How many ATP molecules need to be converted to ADP to link two glucose molecules?
None. Here we are talking of the synthesis of disaccharides. The biological mechanism entails the reaction known as "condensation", where two monosaccharide molecules, as glucose, join together to form a disaccharide. Condensation reaction involves the loss of a water molecule per two monosaccharides in a chemical reaction. Two OH groups, one from each sugar molecule, come together to release a water molecule and form an oxygen bridge between sugar molecules. One of the OH groups is attached to the anomeric carbon (the carbon that has 2 oxygens bonded to it).
How many atoms of carbons are in galactose?
Glucose (C6H12O6) is a monosaccharide that contains twelve hydrogen atoms, six carbon atoms and six oxygen atoms. A glucose and fructose molecule combine to create a sucrose molecule.
