Racemic crystallography is a technique used in structural biology where crystals of a protein molecule are developed from an equimolar mixture of an L-protein molecule of natural chirality and its D-protein mirror image. L-protein molecules consist of 'left-handed' L-amino acids and the achiral amino acid glycine, whereas the mirror image D-protein molecules consist of 'right-handed' D-amino acids and glycine. Typically, both the L-protein and the D-protein are prepared by total chemical synthesis. (Wikipedia).

Isolating a logarithm and using the power rule to solve
π Learn how to solve logarithmic equations. Logarithmic equations are equations with logarithms in them. To solve a logarithmic equation, we first isolate the logarithm part of the equation. After we have isolated the logarithm part of the equation, we then get rid of the logarithm. This i
