BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The chirality of an amino acid results from the fact that its alpha carbon: C) is bonded to four different chemical groups.

Detailed explanation-2: -Chirality is a property of an item that cannot be superimposed on its mirror image, as seen in the left and right hands. Most biological molecules, such as amino acids, are chiral. Cells can also be chiral if they have LR asymmetry and apico-basal polarity.

Detailed explanation-3: -An interesting aspect of most amino acids is that they exist in left and right handed forms, and this is called chirality. Life on Earth is made of left handed amino acids, and this may be a result of how these molecules formed in space.

Detailed explanation-4: -The amino acids are all chiral, with the exception of glycine, whose side chain is H. As with lipids, biochemists use the L and D nomenclature. All naturally occuring proteins from all living organisms consist of L amino acids.

Detailed explanation-5: -All the 20 standard amino acids contain at least one chiral carbon, except for glycine, because it contains two hydrogen atoms attached to its -carbon atom. Amino acid isoleucine and threonine contain two chiral carbons.
