Yes hydrogen is present in protein back bone and peptide side chains. In addition proteins are rich in Carbon hence known as organic molecule. Traces of sulfur also their in aminoacids such as serine and threionine
No; proteins can contain other elements, such as sulfur.
Yes
Compounds that contain ONLY carbon and hydrogen are named as 'hydrocarbons'. Some examples;_ Methane, Ethene, Octane. Alcohols and carboxylic acids are NOT hydrocarbons, because they also contain oxygen.
... called "hydrocarbons".
For example, all hydrocarbons.
Compounds that contain carbon-hydrogen bonding are collectively termed organic compounds. These are simply compounds that would contain hydrogen and carbon elements.
hydrocarbons hydrocarbons is a good answer but they may also contain elements other than carbon and hydrogen such as nitrogen and oxygen
Organic Compound (ie Carbohydrates, Lipids, Proteins) all contain Carbon and Hydrogen.
The elements that hydrocarbons contain are: -Hydrogen -Carbons
of the choices: proteins starches nucleotides lipids nucleotides are not macromolecules
Hydrocarbons contain carbon and hydrogen.
Saturated hydrocarbons contain only single bonds, such as hexane. Unsaturated hydrocarbons contain either double or triple bonds, such as hexene and hexyne.
Compounds are called Hydrocarbons.They should only contain C and H.
Hydrocarbons are organic because they contain carbon and hydrogen.
carbon and hydrogen
No, all hydrocarbons contain carbon.
They are not proteins, but they contain proteins.
... called "hydrocarbons".
Yes, it is correct.
