+'''タンパク質'''は、[[human body/ja|人体]]にとって不可欠な[[nutrient/ja|栄養素]]である。体組織の構成要素の一つであり、燃料源としても機能する。燃料として、タンパク質は[[carbohydrate/ja|炭水化物]]と同じくらいの[[energy density/ja|エネルギー密度]]を提供する： 1グラムあたり4[[:en:Calories|kcal]]（17[[:en:Joule|kJ]]）であるのに対し、[[lipid/ja|脂質]]は1グラムあたり9kcal（37kJ）である。 栄養学的見地から見たタンパク質の最も重要な側面と特徴は、その[[amino acid/ja|アミノ酸]]組成である。
