enzymatic browning reaction in apples or potatoes, etc. Some preservation methods require foods to be sealed after treatment to prevent recontamination with microbes; others, such as drying, allow food to be stored without any special containment for long periods.
Common methods of applying these processes include drying, spray drying, freeze drying, freezing, vacuum-packing, canning, preservin

a sticky end. One of the earlier enzymes to be used, it is popular for historical reasons, but also because digestion leaves a GATC overhang compatible with many other enzymes. Persistent issues with this specific enzyme spontaneously failing to generate cloneable fragments necessitate aliquoting prior to use. Engineered variants of the enzyme have been created in order to avoid star activity.

1.1. 실험 목적
트립신(Trypsin)은 이자액에서 분비되는 단백질 분해효소로 단백질의 소화에 있어서 펩신과 함께 가장 중요한 효소이다. 효소는 기질과 결합하여 효소-기질 복합체(enzyme-substrate complex)를 형성함으로써 반응의 활성화 에너지(activation energy)를 낮추는 촉매 역할을 한다.

enzyme)라고 부른다. 효소의 기능은 온도, pH (수소이온농도) 등 환경 조건에 따라 영향을 받는다. 효소는 화학적 촉매와 같이 반응 물질의 활성화 에너지(activation energy)를 낮추어 반응 속도를 촉진시킬 뿐, 자신은 화학반응에 직접 참여하지 않는다.
효소는 생체 내에 존재하는 고분자 생물학적 촉매제이
