How do $\alpha-D-$glucose and $\beta-D-$glucose differ from each other with respect to the $C-1$ carbon?

$A$ carbohydrate that cannot be hydrolysed to simpler forms is called:

$(i) \ CHO-(CHOH)_3-CH_2OH \xrightarrow{4HIO_4} \text{Product}$
$(ii) \ CH_2OH-(CHOH)_4-CH_2OH \xrightarrow{5HIO_4} \text{Product}$
\text{The ratio of moles of formic acid obtained in reaction } $(i)$ \text{ and reaction } (ii) \text{ is:}
