Lactic acid and alanine were shown to be oxyand amino-propionic acids respectively; glycollic acid and glycocoll, oxyand amino-acetic acids; salicylic and benzamic acids, oxyand amino-benzoic acids.
These decomposition products include: glycocoll or aminoacetic acid, NH 2 CH 2 Oooh, alanine d ucts.
T' rhos, horse, o15pov, urine), benzoyl glycocoll or benzoyl amidoacetic acid, C 9 H 9 NO 3 or C 6 H 5 CO NH CH 2 CO 2 H, an organic acid found in the urine of horses and other herbivorae.
It is also formed by heating benzoic anhydride with glycocoll (Th.
The first aliphatic diazo compound to be isolated was diazoacetic ester, CH N2 CO 2 C 2 H 5 i which is prepared by the action of potassium nitrite on the ethyl ester of glycocoll hydrochloride,HCl NH2 CH2 C02C2H 5 -1-KNO 2 =CHN 2 CO 2 C 2 H 5+ KCI+2H 2 O.
On reduction it yields ammonia and glycocoll (aminoacetic acid).
By direct union with glycocoll acid, it yields glycocyamine, NH2 (HN): C NH CH 2 CO 2 H, whilst with methyl glycocoll (sarcosine) it forms creatine, NH2 (NH): C N(CH3) CH2 C02H.
On heating with hydrochloric acid at 180-200° C. it is decomposed; the products of the reaction being glycocoll, ammonia, formic acid and carbon dioxide.
