Define an amino acid. What is the difference between essential and non essential amino acid? In the biosynthesis of serotonin, what is the functional group produced upon nucleophilic addition of the primary amine to the aldehydic portion of pyridoxyl phosphate? (a) Oxime (b) Enamine (c) I...
Aniline isa benzene derivative with the chemical formula of C6H5NH2. It is an aromatic amine also known asaminobenzeneorphenylamine. Aniline is acolorless to brownliquidwith a characteristicpungent odor. It is aflammable, slightly water soluble and it isoily. Itsmelting point and boiling pointar...
There is a carbonyl centre in a thioester that is reactive towards the nucleophiles, including water. Therefore, these chemical compounds are common intermediates of the conversion of alkyl halides into alkyl thiols. Moreover, a thioester can combine with an amine to give an amide. ...
aThis structural difference accounts for the outcome of their enzymatic acylation. Due to the steric hindrance around the amine group of 1 that acts as the nucleophile attacking the acyl enzyme intermediate to form the amide, 这个结构区别占他们的酶酰化产物的结果。 由于位的妨碍在作为nucleophile攻击...
Pauling (1948) proposed a relationship between the "ionic character" of a bond and the difference in electronegativities of the two elements. Electronegativity is the tendency of an atom to attract electrons toward itself. Table 2(a) shows the electronegativity values for elements in the first ...
The main difference between nylon and polyamide is that polyamide is a general term for a family of synthetic polymers that feature amide linkages in their molecular structure, while nylon is a specific type of polyamide. Reference: 1. “Polyamide.” Encyclopedia Britannica. ...
Naltrexone is an inhibitor that is used in the management of alcohol and opiate dependence. The functional group indicated by the arrow is classified as a ___ amine. (A) primary (B) secondary (C) tertiary (D) quaternary The difference between amino acids is normally due...
Acylation forms esters or amides depending on the nucleophile (alcohol or amine), while acetylation always forms an ester or amide with an acetyl group. Specificity Acylation is less specific and can add various acyl groups, whereas acetylation is more specific and always adds an acetyl group. ...
Amide" is an organic compound containing a carbonyl group linked to nitrogen, while "Amine" is an organic compound derived from ammonia by replacement of one or more hydrogen atoms by organic groups. Difference Between Amide and Amine Table of Contents ...
(organic compound) Any of a class of organic compounds consisting of various numbers of amino acids in which the amine of one is reacted with the carboxylic acid of the next to form an amide bond. Enzyme (biochemistry) A globular protein that catalyses a biological chemical reaction. Peptide...
