Choose the correct statement regarding the stereochemistry of amino acid

1. 16 amino acid except (Thr, Ile, Cys, Gly) L Fischer projection is equal to S and D is equal to R configuration 

2. Thr, Ile is special case because of two chiral center exist in L – Ile/Thr – 2S,3R and D-Ile/Thr–2R,3S configuration  

3. Cys exiest in L- Cys – R & D- Cys – S configuration 

4. Gly is optically inactive
