What are the 4 carbohydrates?

Carbohydrates are divided into four types: monosaccharides, disaccharides, oligosaccharides, and polysaccharides.

Is ribose a sugar?

ribose, also called D-ribose, five-carbon sugar found in RNA (ribonucleic acid), where it alternates with phosphate groups to form the “backbone” of the RNA polymer and binds to nitrogenous bases.

What do you mean by deoxyribose sugar?

Definition of deoxyribose : a pentose sugar C5H10O4 that is a structural element of DNA.

What are the two deoxyribose sugar?

Deoxyribose, also known as D-Deoxyribose and 2-deoxyribose, is a pentose sugar (monosaccharide containing five carbon atoms) that is a key component of the nucleic acid deoxyribonucleic acid (DNA). It is derived from the pentose sugar ribose.

Is deoxyribose a hexose sugar?

For most hexoses, the six-member ring is the most common, whereas a five-member ring is characteristic of pentoses, such as ribose and deoxyribose. The most common hexoses are glucose, galactose, mannose, and fructose.

What is the difference between deoxyribose and ribose quizlet?

ribose is a pentose sugar, whereas deoxyribose is a hexose sugar. deoxyribose is found in RNA, whereas ribose is found in DNA. ribose binds a phosphate at the 3′ position, whereas deoxyribose binds a phosphate at the 2′ position. deoxyribose has one less oxygen molecule than ribose.

What element is in adenine that is not in carbohydrates?

Adenine is a molecule made of carbon, nitrogen, and hydrogen atoms. Its chemical formula is C5H5N5. When a base such as adenine attaches to ribose and phosphate, it forms a nucleotide. Adenine belongs to a nucleotide group called purines.

Is deoxyribose a reducing sugar?
