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
