and.Racine.2010)..In.another.study.done.in.1948,.Cardinal.and.Hedrick.found.
that.amino.acids.together.with.ammonia.account.for.more.than.95%.of.the.
total.nitrogen.concentration.in.the.CSL..The.highest.amino.acids.presented.
were.alanine,.glutamic.acid,.and.arginine.(Cardinal.and.Hedrick.1947)..This.
is.in.accordance.with.Saha.and.Racine.(2010),.who.also.demonstrated.large.
amounts.of.these.amino.acids.
