Question: Alanine is the only alpha-amino acid that does not have a chiral carbon. (a) True (b) False Alanine:- Alanine is an alpha amino acid that helps in biosynthesis of proteins. It contains an amine group and a carboxylic acid group, both attached to central...
Ketone (n.) One of a large class of organic substances resembling the aldehydes, obtained by the distillation of certain salts of organic acids and consisting of carbonyl (CO) united with two hydrocarbon radicals. In general the ketones are colorless volatile liquids having a pungent ethereal odor...
Ketone bodies are the three carbonyl compounds that the body produces under starvation conditions when glucose is not readily available. They are Acetone, 3-B-hydroxybutyrate (3HB), and acetoacetate. Answer and Explanation:1 Diabetic ketoacidosis is very serious. This is because it can result in ...
Ketone: A ketone is considered as a functional group that comprises a carbonyl group with two carbons attached to it. Because the electronegativity of oxygen is significantly higher as compared to carbon in the carbonyl group, the carbonyl group shows nucleophilic reactions. ...
In organic chemistry, an "enamine" is the rearrangement product of an imine, itself the reaction product of a carbonyl compound — an aldehyde or ketone — with either ammonia or an amine — primary or secondary. Derivation of the term is from the words "alkene" and "amine" — the two ...
