steroids two covalent the number of double bonds chemical groups 2 male female effects proteins shapes and chemical characteristics Because carbon has a valence of 4, it can form four covalent bonds with other atoms. Such versatility of carbon allows for building the skeletons of organic molecules, including important biomolecules. For example, carbon skeletons in the shape of four fused rings make up some of which are sex hormones. Estradiol, a sex hormone, and testosterone, a It leads to different sex hormone, are very similar in structure, differing only in two allowing them to bind to molecules on the surface of different target such as the differences between the lions in the photo. cells and result in different

The naturally-occurring amino acid L-serine (NH2-CH(COOH)-CH2-OH, dry form) shares all of the following features with the naturally-occurring amino acid D-serine, except: the same three-dimensional arrangement of covalent bonds the same stoichiometry the same number of covalent bonds the exact same atoms the same number of atoms
