PHARMA RACEMATES. "About 25% of common drugs are racemates, i.e., mixtures of their optical or spatial isomers (stereoisomers or enantiomers). The currently available evidence suggests that for the enantiomers of many chiral drugs there are clear functional differences between the constituent enantiomers and the racemate." https://lnkd.in/ef9kgYu View in LinkedIn

"20 MILLION CHEMICAL COMPOUNDS are known and a number of them are the so-called isomers. Isomers in chemistry are compounds with identical molecular formulas but differing in the nature of the sequence of the bonding of their atoms in space." https://lnkd.in/ef9kgYu View in LinkedIn

MOLECULAR FLEXIBILITY. "An examination of a very large number of enantiomer pairs...shows a general rule: the members of an enantiomer pair will smell alike when the molecules are rigid, and will smell different when they are flexible." https://lnkd.in/eenjdnB View in LinkedIn

D-AMINO ACIDS IN METEORITES. "Murchison contains common amino acids such as glycine, alanine and glutamic acid as well as unusual ones like isovaline and pseudoleucine. A complex mixture of alkanes was isolated as well, similar to that found in the Miller–Urey experiment." https://lnkd.in/e6T2vir View in LinkedIn

ENANTIOMERS are opposite chiral pairs, one left- and the other right-handed. "The most surprising phenomena in the perception of smell are connected with optical isomerism...chiral differentiation was also considered one of the primary principles of smell perception...enantiomers may differ in aroma." https://lnkd.in/enRqV7d View in LinkedIn

CREATING CHIRALS. "It is possible to create "asymmetrical molecules of life" in space-like conditions from a mixture that does not contain any chiral substances...lends further weight to the idea that chiral asymmetry originates in space." https://lnkd.in/e_DRbaG View in LinkedIn

FLAVOR AND AROMA CHIRALITY. Three factors are true in gustation. "High similarity of aromas between different compounds with very dissimilar chemical structures; differing character of aroma between molecules of chemical compounds with very similar structures; the phenomenon of isomerism, occurring only in organic chemistry." https://lnkd.in/enRqV7d View in LinkedIn

AUTHENTICITY assessments of food flavors and essential oils has spawned a significant literature. https://lnkd.in/e7dadSh View in LinkedIn

CHIRAL MOLECULES AND METEORITES. "Specifically, they found a 1.3% reduction...in the amount of left-handed alanine...is of the same order of magnitude as the asymmetric fraction of amino acids discovered in primitive meteorites." https://lnkd.in/e_DRbaG View in LinkedIn
