Document Summary
In weak acid that is a polypro tic acid, there are more possible in ection points and other kinds of in ection points. In this case, ph doesn"t always equal pka. Stereoisomers: d and l forms: d form is chiral carbon with oh on right, l form is chiral carbon with oh on left, generally, only encounter d form in biological systems so we will focus on that. Monosaccharides nomenclature conventions: numbering and d/l forms. Alcohol -> aldehyde -> carboxylic acid: esteri cation, phosphorylation, glycoside formation. Two monosaccharides linked by a glycosidic bond. Linkages are named by - or -conformation and by which carbons are connected: ex. Can have linear and branched connections: unique to carbohydrates. Reducing end contains anomeric carbon that can form carbonyl if linearized: non-reducing end does not contain this. N-h group of amines substitute for oh group. Oh group on anomeric carbon interacts with molecule containing an amino group. Oh on anomeric carbon was beta since.
