WebEphedrine is a non-catecholamine sympathomimetic with cardiovascular effects similar to those of epinephrine: increased blood pressure, heart rate and contractility.Like pseudoephedrine it is a bronchodilator, with pseudoephedrine having considerably less effect.. Ephedrine may decrease motion sickness, but it has mainly been used to … WebAn amino acid has the general formula H₂N-CH (R)-COOH, where R stands for the different acids. Notice that the central C atom is chiral — it has four different groups attached — so the molecule can exist as a pair of enantiomers (nonsuperimposable mirror images). One of these is the D isomer, and the other is L (i.e. a pair of R/S isomers).
