The similarities and differences between the structure of ethynyl estradiol and norethindrone have to be explained. The similarities between the structure of ethynyl estradiol and estradiol and progesterone and norethindrone have to be explained. Concept Introduction: Steroid: Steroids are a type of organic compound having a molecular structure with four rings connected to each other. There are three types of steroids. They are mineralocorticoids, glucocorticoids and sex hormones. There are mainly three female sex hormones namely estrone, estradiol and progesterone. Estrone and estradiol are called estrogens which help in regulating menstrual cycle as well as developing the secondary sex characteristics in a female. Progesterone helps in preparing the uterus for conception. Ethynyl estradiol is a synthetic estrogen whereas norethindrone is a synthetic progestin. Most of the birth control pills are a mixture of ethynyl estradiol and norethindrone.

The carbon-nitrogen peptide bond is rigid, but rotation can take place about the bond between the nitrogen and a-carbon atoms and the bond between the a-carbon and the carbonyl carbon atom. These bond angles define the conformation of the peptide chain.

Please give an intuitive explanation of the difference, if any, between toxicokinetics and pharmacokinetics.

A protein biochemist attempted to determine the amino acid sequence of a decapeptide. The results from the trypsin, chymotrypsin, and cyanogen bromide treatments are shown: ⚫ Trypsin digestion gave two fragments with multiple residues (not in order): • T1: Ala, Arg, Phe, Gly, Thr, Trp, Tyr o T2: Lys, Met, Val Chymotrypsin digestion gave four fragments with multiple residues (not in order): • CT1: Ala, Phe • CT2: Thr, Trp • CT3: Lys, Met, Tyr, Val 。 CT4: Arg, Gly ⚫ Treatment with cyanogen bromide yielded a single amino acid, methionine, and a nonapeptide. What is a possible sequence of the decapeptide? Use three-letter abbreviations in your answer, and add a dash between each residue.
