I'm looking for a table or another kind of schema where I can find which type of carbon atoms (sp3, sp2 etc.) are present in each amino-acid. In my biochemistry books these informations are not available.

I looked also on pubchem (e.g. glycine), and I found some information about alanine, aspartic acid, methionine.

    $\begingroup$ I didn't downvote you but it is beneficial if you put how much work you have been done so far. Also, please clarify your info (e.g., see Nisarg Bhavsar's comment elsewhere). $\endgroup$

    $\begingroup$ For instance, carboxylic carbon and carbonyl oxygen in glycine is $\mathrm{sp^2}$. The rest of the atoms in the molecule is $\mathrm{sp^3}$ ($\ce{C,N,O}$. It is more complicated than that but for your level of knowledge, this is good enough $\endgroup$

    $\begingroup$ Also remember, the oxygens on carbonyl groups in both structures (alanine and aspartic acid) you have just put are $\mathrm{sp^2}$. $\endgroup$

    $\begingroup$ It is not tabulated because you should be able to figure it out for yourself if you ever need to. If you pick up a good general chemistry textbook somewhere it will explain hybridisation. And there are lots of resources on the Internet to learn from, too. Mathew's comments are pretty much it, actually. $\endgroup$
