Which macromolecule is the 5 carbon Deoxyribose?
nucleotides
A nucleic acid is a polymeric macromolecule made up of repeated units of monomeric ‘nucleotides’ composed of a nitrogenous heterocyclic base which is either a purine or a pyrimidine, a pentose (five carbon) sugar (either ribose or 2′-deoxyribose), and one to three phosphate groups.
Which type of biomolecule has a carbon ring structure?
Monosaccharides
Monosaccharides may exist as a linear chain or as ring-shaped molecules; in aqueous solutions, they are usually found in the ring form. The chemical formula for glucose is C6H12O6. In most living species, glucose is an important source of energy.
What lipids are in DNA?
DNA forms TC with three main lipids: phosphatidylcholine (PC), phosphatidylethanolamine (PE) and sphingomyeline (SM), the addition of other lipids increases or decreases these interactions [26].
Does lipids have a ring like structure?
Cholesterol is a member of the sterol family, the only lipid classified as a ring structure. In fact, it has a ring “system” of tetracycline elements; one of the rings joins back on itself in a double bond, thus fortifying the steroid properties of the element.
Is deoxyribose a macromolecule?
Nucleic acids are macromolecules that store, transmit and express the genetic information of a cell. DNA is the stored genetic material. The sugars in RNA are ribose, and in DNA are deoxyribose.
How many carbons are in deoxyribose?
five-carbon
deoxyribose, also called d-2-deoxyribose, five-carbon sugar component of DNA (q.v.; deoxyribonucleic acid), where it alternates with phosphate groups to form the “backbone” of the DNA polymer and binds to nitrogenous bases.
Do lipids have a carbon backbone?
They have a glycerol or sphingosine backbone to which two fatty acid chains and a phosphate-containing group are attached. Steroids are another class of lipids. Their basic structure has four fused carbon rings.
Is fatty acid a lipid?
Fatty acids are common components of complex lipids, and these differ according to chain length and the presence, number and position of double bonds in the hydrocarbon chain. Fatty acids and complex lipids exhibit a variety of structural variations that influence their metabolism and their functional effects.
What are monomers of a lipid?
Glycerol and fatty acids are the monomers of lipids. Lipids include waxes, oils and fats. Some are used for energy storage.
Are lipids composed of carbon rings?
Phospholipids make up the matrix of membranes. They have a glycerol or sphingosine backbone to which two fatty acid chains and a phosphate-containing group are attached. Steroids are another class of lipids. Their basic structure has four fused carbon rings.
Which lipid structure contains carbon rings quizlet?
Steroids are composed of a backbone of four fused carbon rings and are formed from a cholesterol precursor in body cells.
What is the difference between 1′ and 5′ carbons in a deoxyribose?
As a convention, the carbons in a deoxyribose are numbered with primes to differentiate between them. The 1’ carbon (said as “the one prime carbon”) is the carbon that will be bonded to the nitrogenous (nucleic acid) base. The 5’ carbon will be on the opposite side of the ring, and is not part of the ring structure.
What is the structure of deoxyribose in DNA?
In DNA, deoxyribose exists as a five-membered ring. As seen in the graphic, deoxyribose has lost an oxygen molecule form one of the carbons in the ring. While this may seem like a simple change, it drastically affects DNA’s resistance to being broken down by hydrolysis.
What is the difference between deoxyribose and pentose ribose?
Ribose – A pentose molecule bound to 5 oxygen molecules, 1 more than deoxyribose. DNA – A nucleic acid polymer made from many individual nucleotides linked by phosphodiester bonds. Nucleic Acid Base – The purine or pyrimidine attached to deoxyribose or ribose that create a nucleotide.
How many cholesterol molecules are in the lipid bilayer?
This illustration shows five cholesterol molecules (the black structures with four conjoined rings) inserted into the lipid bilayer. Most of the cholesterol molecule in non-polar and therefore associations with the non-polar fatty acid tails of the phospholipids.
