The effects of age and sex on the plasma free amino acid pattern of healthy men and women aged from 80 to 100 years were compared with those in younger adults (20 to 45 years old). Plasma amino acid concentrations were determined by ion-exchange chromatography on a 6300 Beckman analyzer. The plasma concentrations of valine, leucine, isoleucine, proline, glutamine + glutamic acid and phenylalanine were higher in males than in females. Citrulline, half-cystine, histidine, glutamine+glutamic acid, lysine, ornithine and phenylalanine plasma concentrations and the total plasma amino acids were higher in elderly than in younger subjects.
将80至100岁健康男性和女性的血浆游离氨基酸模式的年龄和性别影响与年轻成年人（20至45岁）进行了比较。血浆氨基酸浓度通过在贝克曼6300分析仪上的离子交换色谱法测定。缬氨酸、亮氨酸、异亮氨酸、脯氨酸、谷氨酰胺+谷氨酸和苯丙氨酸的血浆浓度男性高于女性。老年人的瓜氨酸、半胱氨酸、组氨酸、谷氨酰胺+谷氨酸、赖氨酸、鸟氨酸和苯丙氨酸血浆浓度以及总血浆氨基酸高于年轻受试者。
