Is a nucleotide consisting of an adenine base three phosphate groups and a sugar?
ATP is a nucleotide consisting of an adenine base attached to a ribose sugar, which is attached to three phosphate groups. These three phosphate groups are linked to one another by two high-energy bonds called phosphoanhydride bonds.
What are the cells key information carrying molecules?
Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are important information-carrying molecules. In all living cells, DNA holds genetic information and RNA transfers genetic information from DNA to the ribosomes. Ribosomes are formed from RNA and proteins.
Is a polymer of glucose quizlet?
Starch is a polymer of glucose, cellulose is not. Starch and cellulose are both made from glucose but have different linkages.
What characteristic is shared by sucrose and maltose?
What is one characteristic shared by sucrose and maltose? They are all disaccharides.
Is a glucose polymer found in animals stored form of glucose?
The polysaccharide storage form of glucose in animals is glycogen whereas in plants it is starch Both if these are polymers of glucose with l4 glycosidic.
What is nucleotides polymer?
A nucleotide is the basic building block of nucleic acids. RNA and DNA are polymers made of long chains of nucleotides. A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base.
What are the four types of biological macromolecules?
There are four major classes of biological macromolecules:
- carbohydrates.
- lipids.
- proteins.
- nucleic acids.
What is a polymer of glucose?
Polymers of glucose are known as the glucans. These glucans are types of homopolysaccharides. Amylose, cellulose, and glycogen are examples of polymers of glucose.
Is cellulose a polymer of glucose?
Cellulose is a linear polymer glucan and is composed of glucose units (> 10 000), which are linked by β-(1–4)-glycosidic bonds. The regular arrangement of the hydroxyl groups along the cellulose chain leads to the formation of H-bridges and therefore to a fibrillar structure with crystalline properties.
What characteristic do glucose fructose and galactose share?
Glucose, galactose, and fructose are monosaccharide isomers, which means they all have the same chemical formula but differ structurally and chemically. Disaccharides form when two monosaccharides undergo a dehydration reaction (a condensation reaction); they are held together by a covalent bond.
Is Lactose a disaccharide?
Lactose is a disaccharide that can be hydrolyzed by the lactase enzyme lactase-phlorizin hydrolase (LPH) into glucose and galactose, which are actively absorbed in the small intestine (Fig. 21.1).
