A kinin is any of various structurally related polypeptides, such as bradykinin and kallikrein. They are members of the autacoid family.

They act locally to induce vasodilation and contraction of smooth muscle.

It is a component of the kinin-kallikrein system.

Their precursors are kininogen.

In botany, plant hormones cytokinins were first called kinins, but the name was changed to avoid confusion.

Aspirin inhibits the activation of kallenogen by interfering with the formation of kallikrien enzyme which is essential in the process of activation.

Deborah ("Debby") Anne Boone (born September 22, 1956) is an American singer and stage actress. She is best known for her 1977 hit, "You Light Up My Life," which spent a then record ten weeks at No. 1 on the Billboard Hot 100 chart and led to her winning the Grammy Award for Best New Artist the following year. Boone later focused her music career on country music resulting in the 1980 No. 1 country hit, "Are You on the Road to Lovin' Me Again". In the 1980s, she recorded Christian music which garnered her four top 10 Contemporary Christian albums as well as two more Grammys. Throughout her career, Boone has appeared in several musical theater productions and has co-authored many children's books with husband, Gabriel Ferrer.

Debby Boone was born in Hackensack, New Jersey, the third of four daughters born to singer-actor Pat Boone and Shirley Foley Boone, daughter of country music star Red Foley. When Boone was 14 years old, she began touring with her parents and three sisters: Cherry, Lindy and Laury. The sisters first recorded with their parents as The Pat Boone Family and later as the Boones or Boone Girls. They primarily recorded gospel music, although the sisters also released singles for the Motown and Curb labels that were remakes of secular pop music featuring Debby as the lead vocalist.
