what is The helix that forms in a protein chain as a result of hydrogen bonds and other weak forces is an example of?
Secondary Structure of protein
What bond holds the bases together in a DNA molecule?
Base pairs in DNA are attached to each other via hydrogen bonds. The base pairs are attached to the backbone by covalent bonds.
Do saturated fatty acids have the maximum number of hydrogen atoms?
It depends on the length of the fatty acid chain. A fatty acid that has the maximum number of hydrogen atoms is saturated. The maximum number of hydrogen atoms will occur when the carbon atoms are all single-bonded to one another (no double bonds).
If one fatty acid is more saturated than another fatty acid of equal chain length it has?
It has more hydrogen atoms and fewer double bonds between carbon atoms.
Gas needed for electron transport chain?
The "gas" needed for the electron transport chain is Hydrogen. In the electron transport chain its not Hydrogen gas H2 but a Hydrogen Ion H negative that flows across the membrane to produce engery.
What kind of bonds hold the chain of building blocks together?
The atomic covalent bonds that keep the building blocks joined together are of the same type as those that keep the chain-links linked.
Why there are no hydrogen bonds present in RNA?
There are no hydrogen bonds present because RNA consists of a single stranded nucleotide chain.
What is the difference between interchain and intrachain hydrogen bonds in the secondary structure of proteins?
IntrAchain H-bonds stabalize bonds between the same polypeptide chain (alpha-helices). IntErchain- H-bonds stablized between different polypeptide chain. (beta- structures)
What kind of fatty acid has only single bonds?
In saturated fatty acids are there only single bonds in the carbon chain.
Why is the number of hydrogen atoms in cylcohexane two less than in a hexane?
Cyclo prefix indicates that the carbons are not a straight chain but is in a circle. the bonds between carbons to form the circle requires 2 less possible bonds for hydrogen.
What is the difference between a saturaded and unsaturaded fatty acid?
The difference between a saturated and unsaturated fatty acid are the number of hydrogen atoms and double carbon bonds in the fatty acid chain. A saturated fatty acid has no carbon double bonds, two hydrogen atoms for each carbon atom along the chain and three for the carbon atom at each end. In an unsaturated fatty acid chain some of the hydrogen atoms are replaced by a double bond between neighboring carbon atoms. Mon-unsaturated and poly-unsaturated fatty acids differ in the number of double carbon bonds in the chain, and thus the total number of hydrogen atoms.
Hydrogen bonds between different parts of the polypeptide chain result in which level of protein structure?
Tertiary structure

Secondary Structure of protein
What bond holds the bases together in a DNA molecule?
Base pairs in DNA are attached to each other via hydrogen bonds. The base pairs are attached to the backbone by covalent bonds.
A fat is called what if all the fatty acid chains are single bonded to two other carbons and two hydrogens?
If a fatty acid has a completely single-bonded carbon chain with as many hydrogen atoms as possible bound to the chain, it is refered to as a "saturated" fat. It is literally saturated with hydrogen atoms. If the chain has one or more double bonds, those double bonds reduce the number of hydrogen atoms, and so that is an "unsaturated" fat.
Differentiate between secondary and tertiary structure by describing the parts of the polypeptide chain that participates in the bonds that hold together each level of structure?
Secondary tertiary is the R groups interactions that are ionic. The polypeptide chain also has disulfide bond, and hydrophobic interactions.
What is saturated margerine?
Margarine is vegetable oil which has been hydrogenated. Oil is is unsaturated which means that the hydrocarbon chain has double bonds which can be broken and hydrogen added making the molecule saturated. Double bonds cause the molecule to be kinked which means when many of these molecules are present, they can not pack as tightly together causing oil to be liquid. Once the double bonds are broken, and hydrogen takes those spots, the molecules becomes straight. When the molecules become straight they can pack together much more tightly. This results in the oil becoming solid which is why margarine is a solid.
