What is adenine and guanine held together with?
The Cytosine, Guanine, Adenine and Thymine bases present in DNA are molecules that are held together by intermolecular hydrogen bonds. This bond occurs between an electronegative atom (known as a hydrogen bond acceptor) and a hydrogen atom attached to another electronegative atom (known as a hydrogen bond donor).
What inorganic molecules make up glucose?
Inorganic molecules are usually defined as any molecule that doesn't contain the element carbon. There are some exceptions, such as carbon dioxide, which is usually defined as inorganic, even though it contains carbon and is a product of some biological reactions.
Does KF form a hydrogen bond?
No - hydrogen needs to be present and bonded to a very electronegative element for hydrogen bonding to occur.
Is lipids present in food?
Lipids are present in vegetable oil, olive oil, and others of biological origin. But they are not present in petroleum, which consists mostly of hydrocarbons.
How many molecules of sulfur tetrafluoride are present in 2.13 moles of this compound?
There are 1.28x10^24 molecules of SF4. 2.13 mol * 6.022x10^23 molecules/mol = 1.28x10^24 molecules.
Are fats used as parts of biological membranes?
Proteins are a major constituent of biomembranes, accounting for as much as 50% of the volume. The primary molecules found in biological membranes around cells are lipids (biological fat or wax molecules).
What is adenine and guanine held together with?
The Cytosine, Guanine, Adenine and Thymine bases present in DNA are molecules that are held together by intermolecular hydrogen bonds. This bond occurs between an electronegative atom (known as a hydrogen bond acceptor) and a hydrogen atom attached to another electronegative atom (known as a hydrogen bond donor).
What type of chemical bond must be present for present for most chemists to define molecules?
Molecules typically refer to atoms that are bound together by covalent bonds. This is the sharing of an electron pair between two nonmetal atoms.
