a.properties

molecular formula	c6h13no2
molar mass	131.17 g mol−1
acidity (pka)	2.36 (carboxyl), 9.60 (amino)

b.description

as an essential amino acid, leucine cannot be synthesised by animals. consequently, it must be ingested, usually as a component of proteins. in plants and microorganisms, leucine is synthesised from pyruvic acid by a series of enzymes:

acetolactate synthase
acetohydroxy acid isomeroreductase
dihydroxyacid dehydratase
α-isopropylmalate synthase
α-isopropylmalate isomerase
leucine aminotransferase

synthesis of the small, hydrophobic amino acid valine also includes the initial part of this pathway.
