Covalent Bonds form large biological molecules
Biochirality is the chirality - of biological molecules, especially the study of the genesis of such chirality - the phenomenon by which two biological molecules are symmetrical.
Proteins are probably the largest class of biological molecules that always contain nitrogen.
Carbon
Oxidising - reducing reactions are important for the synthesis and breakdown of biological molecules?
carbon
Organic molecules contain carbon.
Carbon
enzymes are protein molecules that act as biological catalysts
The large diversity of shapes of biological molecules is possible because of carbon.
To see if biological compounds could form spontaneously on early Earth To see if simple molecules can combine spontaneously. To find out how biological molecules could have first formed How life can evolve from nonliving matter
