All protein molecules are heterogeneous unbranched chains of amino acids. So basically they're related in that protein molecules are pretty much made up of amino acids.

The four chemical elements present in amino acids, I think, are Hydrogen (H), Oxygen (O), Carbon (C), and Nitrogen (N)

I hope i helped... I havent studied this stuff in a while and i have short term memory x__x

Hmm, well i know that the four chemical elements in Amino acids are Hydrogen, Oxygen, Carbon, Nitrogen

I know that Protein molecules have Hyrdrogen, Oxygen and Carbon elements..but the relationship between them I'm not sure..

i think that In both amino acids and proteins one end of each molecule is a carboxyl end which is COOH, and the other end is just an -OH ending..

To combine Protein molecules to other protein molecules, and to combine amino acids to other amino acids, you have to take a Hydrogen element off one end and a Oxygen and Hyrdrogen off the other end to put them together, and thats called Dehydration synthesis

I'm learning about this now, i'm tyring to think of what all i can remember about it, if i remember more i'll edit my answer for you good luck!
