identifying everything

its over

monosaccharide: (linear) fructose/levulose

steroid: cholesterol

nitrogenous base (purine): guanine

monosaccharide: (ring) beta-galactose

nitrogenous base (pyramidine): uracil 

monosaccharide: (ring) beta-fructose

• drawn like this when bonding w/ glucose to create sucrose

steroid: estradiol

monosaccharide: (linear) galactose

monosaccharide: (ring) beta-fructose

• drawn like this in isolation

monosaccharide: (ring) alpha-galactose

monosaccharide: (ring) alpha-fructose

• note: only beta-fructose forms glycosidic bonds w/ alpha-glucose to create sucrose

• lowkey i dont think she’s gonna test us on alpha-fructose

monosaccharide: (ring) beta-glucose

monosaccharide: (ring) alpha-glucose 

nitrogenous base (purine): adenine

monosaccharide: (linear) glucose

monosaccharide: (ring) alpha-fructose

• lowkey i dont think she’s gonna test us on alpha-fructose

nitrogenous base (pyramidine): thymine

steroid: testosterone

nitrogenous base (pyramidine): cytosine

deoxyribose

alpha-glucose + alpha-glucose → alpha-maltose + water

maltose has alpha-1,4 glycosidic bond

alpha-glucose + beta-glucose → beta-maltose + water

maltose has alpha-1,4 glycosidic bond still

beta-galactose + alpha-glucose → alpha-lactose + water

lactose has beta-1,4 glycosidic bond

beta-galactose + beta-glucose → beta-lactose + water

lactose has beta-1,4 glycosidic bond

beta-glucose + beta-glucose → cellobiose + water

cellobiose has beta-1,4 glycosidic/glucosidic bond

alpha-glucose + beta-fructose → sucrose + water

sucrose has alpha,beta-1,2 glycosidic bond (this makes more sense if you used the uhh greek letters)

ribose

cellulose

beta-1,4 glycosidic bonds

starch

amylose: alpha-1,4 (no branching)

amylopectin: alpha-1,4 (no branching), alpha-1,6 (yes branching)

glycogen

alpha-1,4 (no branching), alpha-1,6 (yes branching)

i just wanted to look at this slide more lowkey

chitin

similar to cellulose, modified glucose units to include -nh- (amine) group, still beta-1,4 glycosidic bonds?
