Brit.

/ˌpantəˈθɛnɪk/, U.S.

/ˌpæn(t)oʊˈθɛnɪk/

Origin: A borrowing from Greek, combined with an English element. Etymons: Greek πάντοθεν , -ic suffix.

Etymology: < ancient Greek πάντοθεν from every side ( < παντο- panto- comb. form + -θεν , suffix forming adverbs indicating motion from) + -ic suffix (see quot. 1933 for pantothenic acid n.).

Biochemistry.

pantothenic acid n. an oily, liquid carboxylic acid whose molecule consists of β-alanine linked to a pantoyl residue, and which is widely distributed in plant and animal tissues (mainly as a component of coenzyme A) and is essential for normal carbohydrate and fat metabolism; HOCH₂C(CH₃)₂CHOH·CO·NH(CH₂)₂COOH. Also called vitamin B₅.
