A [[~~hormone~~]] ~~is any of a class of~~ [[~~cell signaling~~|~~signaling molecules~~]] ~~produced by cells in~~ [[gland]]~~s in~~ [[~~multicellular organism~~]]~~s that are transported by the~~ [[~~circulatory system~~]] ~~to target distant organs to regulate~~ [[~~physiology~~]] ~~and~~ [[~~behaviour~~]]~~. Hormones have diverse chemical structures, mainly of 3 classes:~~ [[eicosanoid]]s, [[steroid]]~~s, and~~ [[amino acid]]/[[protein]] ~~derivatives (~~[[amine]]s, [[peptide]]~~s, and~~ [[protein]]~~s). The glands that secrete hormones comprise the endocrine system. The term hormone is sometimes extended to include chemicals produced by cells that affect the same cell (~~[[autocrine signaling|~~autocrine~~]] or [[intracrine|~~intracrine signalling~~]]~~) or nearby cells (~~[[paracrine signalling]]).

+[[Hormone/ja|ホルモン]]とは、[[multicellular organism/ja|多細胞生物]]の[[gland/ja|腺]]の細胞によって産生され、[[circulatory system/ja|循環系]]によって遠くの臓器に運ばれて[[physiology/ja|生理]]や[[behaviour/ja|行動]]を調節する[[cell signaling/ja|シグナル伝達分子]]の一種である。ホルモンは多様な化学構造を持ち、主に3つのクラスに分類される： [[eicosanoid/ja|エイコサノイド]]類、[[steroid/ja|ステロイド]]類、および[[amino acid/ja|アミノ酸]]/[[protein/ja|タンパク質]]誘導体（[[amine/ja|アミン]]類、[[peptide/ja|ペプチド]]類、[[protein/ja|タンパク質]]類）である。ホルモンを分泌する腺は内分泌系を構成する。ホルモンという用語は、同じ細胞（[[autocrine signaling/ja|自己分泌]]または[[intracrine/ja|細胞内シグナル伝達]]）または近くの細胞（[[paracrine signalling/ja|パラクリンシグナル]]）に影響を与える細胞によって産生される化学物質を含むように拡張されることもある。
